This calculation has always been suspect. NFSD has never sanity- checked the READDIR count argument, but the old entry encoders managed the problem correctly. With the commits below, entry encoding changed, exposing the underflow to the pointer arithmetic in xdr_reserve_space(). Modern NFS clients attempt to retrieve as much data as possible for each READDIR request.",

A client can force the send buffer to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC message with garbage data is still correctly formed according to the specification and is passed forward to handlers.

"text": "Issue summary: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow. Impact summary: Applications that use the functions DH_generate_key() to generate an X9.42 DH key may experience long delays. Likewise, applications that use DH_check_pub_key(), DH_check_pub_key_ex() or EVP_PKEY_public_check() to check an X9.42 DH key or X9.42 DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service. While DH_check() performs all the necessary checks (as of CVE-2023-3817), DH_check_pub_key() doesn\u0027t make any of these checks, and is therefore vulnerable for excessively large P and Q parameters. Likewise, while DH_generate_key() performs a check for an excessively large P, it doesn\u0027t check for an excessively large Q. An application that calls DH_generate_key() or DH_check_pub_key() and supplies a key or parameters obtained from an untrusted source could be vulnerable to a Denial of Service attack. DH_generate_key() and DH_check_pub_key() are also called by a number of other OpenSSL functions. An application calling any of those other functions may similarly be affected. The other functions affected by this are DH_check_pub_key_ex(), EVP_PKEY_public_check(), and EVP_PKEY_generate(). Also vulnerable are the OpenSSL pkey command line application when using the \"-pubcheck\" option, as well as the OpenSSL genpkey command line application. The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.",

{
"category": "summary",
"text": "Issue summary: Calling the OpenSSL API function SSL_select_next_proto with an empty supported client protocols buffer may cause a crash or memory contents to be sent to the peer. Impact summary: A buffer overread can have a range of potential consequences such as unexpected application beahviour or a crash. In particular this issue could result in up to 255 bytes of arbitrary private data from memory being sent to the peer leading to a loss of confidentiality. However, only applications that directly call the SSL_select_next_proto function with a 0 length list of supported client protocols are affected by this issue. This would normally never be a valid scenario and is typically not under attacker control but may occur by accident in the case of a configuration or programming error in the calling application. The OpenSSL API function SSL_select_next_proto is typically used by TLS applications that support ALPN (Application Layer Protocol Negotiation) or NPN (Next Protocol Negotiation). NPN is older, was never standardised and is deprecated in favour of ALPN. We believe that ALPN is significantly more widely deployed than NPN. The SSL_select_next_proto function accepts a list of protocols from the server and a list of protocols from the client and returns the first protocol that appears in the server list that also appears in the client list. In the case of no overlap between the two lists it returns the first item in the client list. In either case it will signal whether an overlap between the two lists was found. In the case where SSL_select_next_proto is called with a zero length client list it fails to notice this condition and returns the memory immediately following the client list pointer (and reports that there was no overlap in the lists). This function is typically called from a server side application callback for ALPN or a client side application callback for NPN. In the case of ALPN the list of protocols supplied by the client is guaranteed by libssl to never be zero in length. The list of server protocols comes from the application and should never normally be expected to be of zero length. In this case if the SSL_select_next_proto function has been called as expected (with the list supplied by the client passed in the client/client_len parameters), then the application will not be vulnerable to this issue. If the application has accidentally been configured with a zero length server list, and has accidentally passed that zero length server list in the client/client_len parameters, and has additionally failed to correctly handle a \"no overlap\" response (which would normally result in a handshake failure in ALPN) then it will be vulnerable to this problem. In the case of NPN, the protocol permits the client to opportunistically select a protocol when there is no overlap. OpenSSL returns the first client protocol in the no overlap case in support of this. The list of client protocols comes from the application and should never normally be expected to be of zero length. However if the SSL_select_next_proto function is accidentally called with a client_len of 0 then an invalid memory pointer will be returned instead. If the application uses this output as the opportunistic protocol then the loss of confidentiality will occur. This issue has been assessed as Low severity because applications are most likely to be vulnerable if they are using NPN instead of ALPN - but NPN is not widely used. It also requires an application configuration or programming error. Finally, this issue would not typically be under attacker control making active exploitation unlikely. The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue. Due to the low severity of this issue we are not issuing new releases of OpenSSL at this time. The fix will be included in the next releases when they become available.",

Impact summary: Out of bound memory writes can lead to an application crash or even a possibility of a remote code execution, however, in all the protocols involving Elliptic Curve Cryptography that we\u0027re aware of, either only \"named curves\" are supported, or, if explicit curve parameters are supported, they specify an X9.62 encoding of binary (GF(2m)) curves that can\u0027t represent problematic input values. Thus the likelihood of existence of a vulnerable application is low. In particular, the X9.62 encoding is used for ECC keys in X.509 certificates, so problematic inputs cannot occur in the context of processing X.509 certificates. Any problematic use-cases would have to be using an \"exotic\" curve encoding. The affected APIs include: EC_GROUP_new_curve_GF2m(), EC_GROUP_new_from_params(), and various supporting BN_GF2m_*() functions. Applications working with \"exotic\" explicit binary (GF(2m)) curve parameters, that make it possible to represent invalid field polynomials with a zero constant term, via the above or similar APIs, may terminate abruptly as a result of reading or writing outside of array bounds.

"text": "In the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbpf: Fix DEVMAP_HASH overflow check on 32-bit arches\r\n\r\nThe devmap code allocates a number hash buckets equal to the next power\r\nof two of the max_entries value provided when creating the map. When\r\nrounding up to the next power of two, the 32-bit variable storing the\r\nnumber of buckets can overflow, and the code checks for overflow by\r\nchecking if the truncated 32-bit value is equal to 0. However, on 32-bit\r\narches the rounding up itself can overflow mid-way through, because it\r\nends up doing a left-shift of 32 bits on an unsigned long value. If the\r\nsize of an unsigned long is four bytes, this is undefined behaviour, so\r\nthere is no guarantee that we\u0027ll end up with a nice and tidy 0-value at\r\nthe end.\r\n\r\nSyzbot managed to turn this into a crash on arm32 by creating a\r\nDEVMAP_HASH with max_entries \u003e 0x80000000 and then trying to update it.\r\nFix this by moving the overflow check to before the rounding up\r\noperation.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\r\n\r\nudp: do not accept non-tunnel GSO skbs landing in a tunnel\r\n\r\nWhen rx-udp-gro-forwarding is enabled UDP packets might be GROed when\r\nbeing forwarded. If such packets might land in a tunnel this can cause\r\nvarious issues and udp_gro_receive makes sure this isn\u0027t the case by\r\nlooking for a matching socket. This is performed in\r\nudp4/6_gro_lookup_skb but only in the current netns. This is an issue\r\nwith tunneled packets when the endpoint is in another netns. In such\r\ncases the packets will be GROed at the UDP level, which leads to various\r\nissues later on. The same thing can happen with rx-gro-list.\r\n\r\nWe saw this with geneve packets being GROed at the UDP level. In such\r\ncase gso_size is set; later the packet goes through the geneve rx path,\r\nthe geneve header is pulled, the offset are adjusted and frag_list skbs\r\nare not adjusted with regard to geneve. When those skbs hit\r\nskb_fragment, it will misbehave. Different outcomes are possible\r\ndepending on what the GROed skbs look like; from corrupted packets to\r\nkernel crashes.\r\n\r\nOne example is a BUG_ON[1] triggered in skb_segment while processing the\r\nfrag_list.

"text": "In the Linux kernel, the following vulnerability has been resolved: tcp: properly terminate timers for kernel sockets We had various syzbot reports about tcp timers firing after the corresponding netns has been dismantled. Fortunately Josef Bacik could trigger the issue more often, and could test a patch I wrote two years ago. When TCP sockets are closed, we call inet_csk_clear_xmit_timers() to \u0027stop\u0027 the timers. inet_csk_clear_xmit_timers() can be called from any context, including when socket lock is held. This is the reason it uses sk_stop_timer(), aka del_timer(). This means that ongoing timers might finish much later. For user sockets, this is fine because each running timer holds a reference on the socket, and the user socket holds a reference on the netns. For kernel sockets, we risk that the netns is freed before timer can complete, because kernel sockets do not hold reference on the netns. This patch adds inet_csk_clear_xmit_timers_sync() function that using sk_stop_timer_sync() to make sure all timers are terminated before the kernel socket is released. Modules using kernel sockets close them in their netns exit() handler. Also add sock_not_owned_by_me() helper to get LOCKDEP support : inet_csk_clear_xmit_timers_sync() must not be called while socket lock is held. It is very possible we can revert in the future commit 3a58f13a881e (\"net: rds: acquire refcount on TCP sockets\") which attempted to solve the issue in rds only. (net/smc/af_smc.c and net/mptcp/subflow.c have similar code) We probably can remove the check_net() tests from tcp_out_of_resources() and __tcp_close() in the future.",

To do so, it polls the\nconfig space of the first child device on the secondary bus. If that\nchild device is concurrently removed, accesses to its struct pci_dev\ncause the kernel to oops.\n\nThat\u0027s because pci_bridge_wait_for_secondary_bus() neglects to hold a\nreference on the child device. Before v6.3, the function was only\ncalled on resume from system sleep or on runtime resume. Holding a\nreference wasn\u0027t necessary back then because the pciehp IRQ thread\ncould never run concurrently. (On resume from system sleep, IRQs are\nnot enabled until after the resume_noirq phase. And runtime resume is\nalways awaited before a PCI device is removed.)\n\nHowever starting with v6.3, pci_bridge_wait_for_secondary_bus() is also\ncalled on a DPC event. Commit 53b54ad074de (\"PCI/DPC: Await readiness\nof secondary bus after reset\"), which introduced that, failed to\nappreciate that pci_bridge_wait_for_secondary_bus() now needs to hold a\nreference on the child device because dpc_handler() and pciehp may\nindeed run concurrently. The commit was backported to v5.10+ stable\nkernels, so that\u0027s the oldest one affected.\n\nAdd the missing reference acquisition.\n\nAbridged stack trace:\n\n BUG: unable to handle page fault for address: 00000000091400c0\n CPU: 15 PID: 2464 Comm: irq/53-pcie-dpc 6.9.0\n RIP: pci_bus_read_config_dword+0x17/0x50\n pci_dev_wait()\n pci_bridge_wait_for_secondary_bus()\n dpc_reset_link()\n pcie_do_recovery()\n dpc_handler()",

While this allocation failure is handled properly and request is rejected, it results in syzkaller reports. Additionally, such request may put undue burden on the system which will try to free a lot of memory for a bogus request. Fix it by limiting allowed number of slots to 100. This can easily be extended if we see devices that can track more than 100 contacts.",

Hence __fsnotify_update_child_dentry_flags() function can take a significant amount of time. Since the bulk of this function happens under inode-\u003ei_lock this causes a significant contention on the lock when we remove the watch from the directory as the __fsnotify_update_child_dentry_flags() call from fsnotify_recalc_mask() races with __fsnotify_update_child_dentry_flags() calls from __fsnotify_parent() happening on children. This can lead upto softlockup reports reported by users. Fix the problem by calling fsnotify_update_children_dentry_flags() to set PARENT_WATCHED flags only when parent starts watching children. When parent stops watching children, clear false positive PARENT_WATCHED flags lazily in __fsnotify_parent() for each accessed child.",

This was modified to handle the specific case of -ENXIO separately, allowing the function to proceed without logging the error in this case. However, this change unintentionally left a path where md_autodetect_dev() could be called without confirming that part is a valid pointer.\r\n\r\nThis commit separates the error handling logic by splitting the initial if-condition, improving code readability and handling specific error scenarios explicitly. The function now distinguishes the general error case from -ENXIO without altering the existing behavior of md_autodetect_dev() calls.",

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: reduce rtnl pressure in smc_pnet_create_pnetids_list()
Many syzbot reports show extreme rtnl pressure, and many of them hint
that smc acquires rtnl in netns creation for no good reason [1]
This patch returns early from smc_pnet_net_init()
if there is no netdevice yet.
I am not even sure why smc_pnet_create_pnetids_list() even exists,
because smc_pnet_netdev_event() is also calling
smc_pnet_add_base_pnetid() when handling NETDEV_UP event.
[1] extract of typical syzbot reports

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix bpf_sk_select_reuseport() memory leak
As pointed out in the original comment, lookup in sockmap can return a TCP
ESTABLISHED socket. Such TCP socket may have had SO_ATTACH_REUSEPORT_EBPF
set before it was ESTABLISHED. In other words, a non-NULL sk_reuseport_cb
does not imply a non-refcounted socket.
Drop sk's reference in both error paths.

Summary
In the Linux kernel, the following vulnerability has been resolved:
exfat: fix the infinite loop in exfat_readdir()
If the file system is corrupted so that a cluster is linked to
itself in the cluster chain, and there is an unused directory
entry in the cluster, 'dentry' will not be incremented, causing
condition 'dentry < max_dentries' unable to prevent an infinite
loop.
This infinite loop causes s_lock not to be released, and other
tasks will hang, such as exfat_sync_fs().
This commit stops traversing the cluster chain when there is unused
directory entry in the cluster to avoid this infinite loop.

Summary
In the Linux kernel, the following vulnerability has been resolved:
udp: do not accept non-tunnel GSO skbs landing in a tunnel
When rx-udp-gro-forwarding is enabled UDP packets might be GROed when
being forwarded. If such packets might land in a tunnel this can cause
various issues and udp_gro_receive makes sure this isn't the case by
looking for a matching socket. This is performed in
udp4/6_gro_lookup_skb but only in the current netns. This is an issue
with tunneled packets when the endpoint is in another netns. In such
cases the packets will be GROed at the UDP level, which leads to various
issues later on. The same thing can happen with rx-gro-list.
We saw this with geneve packets being GROed at the UDP level. In such
case gso_size is set; later the packet goes through the geneve rx path,
the geneve header is pulled, the offset are adjusted and frag_list skbs
are not adjusted with regard to geneve. When those skbs hit
skb_fragment, it will misbehave. Different outcomes are possible
depending on what the GROed skbs look like; from corrupted packets to
kernel crashes.
One example is a BUG_ON[1] triggered in skb_segment while processing the
frag_list. Because gso_size is wrong (geneve header was pulled)
skb_segment thinks there is "geneve header size" of data in frag_list,
although it's in fact the next packet. The BUG_ON itself has nothing to
do with the issue. This is only one of the potential issues.
Looking up for a matching socket in udp_gro_receive is fragile: the
lookup could be extended to all netns (not speaking about performances)
but nothing prevents those packets from being modified in between and we
could still not find a matching socket. It's OK to keep the current
logic there as it should cover most cases but we also need to make sure
we handle tunnel packets being GROed too early.
This is done by extending the checks in udp_unexpected_gso: GSO packets
lacking the SKB_GSO_UDP_TUNNEL/_CSUM bits and landing in a tunnel must
be segmented.

This is only one of the potential issues.\n\nLooking up for a matching socket in udp_gro_receive is fragile: the\nlookup could be extended to all netns (not speaking about performances)\nbut nothing prevents those packets from being modified in between and we\ncould still not find a matching socket. It\u0027s OK to keep the current\nlogic there as it should cover most cases but we also need to make sure\nwe handle tunnel packets being GROed too early.\n\nThis is done by extending the checks in udp_unexpected_gso: GSO packets\nlacking the SKB_GSO_UDP_TUNNEL/_CSUM bits and landing in a tunnel must\nbe segmented.\n\n[1] kernel BUG at net/core/skbuff.c:4408!\n RIP: 0010:skb_segment+0xd2a/0xf70\n __udp_gso_segment+0xaa/0x560"

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: sysfs: Fix reference leak in sysfs_break_active_protection()
The sysfs_break_active_protection() routine has an obvious reference
leak in its error path. If the call to kernfs_find_and_get() fails then
kn will be NULL, so the companion sysfs_unbreak_active_protection()
routine won't get called (and would only cause an access violation by
trying to dereference kn->parent if it was called). As a result, the
reference to kobj acquired at the start of the function will never be
released.
Fix the leak by adding an explicit kobject_put() call when kn is NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Defer the free of inner map when necessary
When updating or deleting an inner map in map array or map htab, the map
may still be accessed by non-sleepable program or sleepable program.
However bpf_map_fd_put_ptr() decreases the ref-counter of the inner map
directly through bpf_map_put(), if the ref-counter is the last one
(which is true for most cases), the inner map will be freed by
ops->map_free() in a kworker. But for now, most .map_free() callbacks
don't use synchronize_rcu() or its variants to wait for the elapse of a
RCU grace period, so after the invocation of ops->map_free completes,
the bpf program which is accessing the inner map may incur
use-after-free problem.
Fix the free of inner map by invoking bpf_map_free_deferred() after both
one RCU grace period and one tasks trace RCU grace period if the inner
map has been removed from the outer map before. The deferment is
accomplished by using call_rcu() or call_rcu_tasks_trace() when
releasing the last ref-counter of bpf map. The newly-added rcu_head
field in bpf_map shares the same storage space with work field to
reduce the size of bpf_map.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fat: fix uninitialized field in nostale filehandles
When fat_encode_fh_nostale() encodes file handle without a parent it
stores only first 10 bytes of the file handle. However the length of the
file handle must be a multiple of 4 so the file handle is actually 12
bytes long and the last two bytes remain uninitialized. This is not
great at we potentially leak uninitialized information with the handle
to userspace. Properly initialize the full handle length.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: mesh: Fix leak of mesh_preq_queue objects
The hwmp code use objects of type mesh_preq_queue, added to a list in
ieee80211_if_mesh, to keep track of mpath we need to resolve. If the mpath
gets deleted, ex mesh interface is removed, the entries in that list will
never get cleaned. Fix this by flushing all corresponding items of the
preq_queue in mesh_path_flush_pending().
This should take care of KASAN reports like this:
unreferenced object 0xffff00000668d800 (size 128):

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: wilc1000: fix RCU usage in connect path
With lockdep enabled, calls to the connect function from cfg802.11 layer
lead to the following warning:
=============================

This warning is emitted because in the connect path, when trying to parse
target BSS parameters, we dereference a RCU pointer whithout being in RCU
critical section.
Fix RCU dereference usage by moving it to a RCU read critical section. To
avoid wrapping the whole wilc_parse_join_bss_param under the critical
section, just use the critical section to copy ies data

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: core: reject skb_copy(_expand) for fraglist GSO skbs
SKB_GSO_FRAGLIST skbs must not be linearized, otherwise they become
invalid. Return NULL if such an skb is passed to skb_copy or
skb_copy_expand, in order to prevent a crash on a potential later
call to skb_gso_segment.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Consider the NULL character when validating the event length
strlen() returns a string length excluding the null byte. If the string
length equals to the maximum buffer length, the buffer will have no
space for the NULL terminating character.
This commit checks this condition and returns failure for it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix incorrect list API usage
Both the function that migrates all the chunks within a region and the
function that migrates all the entries within a chunk call
list_first_entry() on the respective lists without checking that the
lists are not empty. This is incorrect usage of the API, which leads to
the following warning [1].
Fix by returning if the lists are empty as there is nothing to migrate
in this case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - resolve race condition during AER recovery
During the PCI AER system's error recovery process, the kernel driver
may encounter a race condition with freeing the reset_data structure's
memory. If the device restart will take more than 10 seconds the function
scheduling that restart will exit due to a timeout, and the reset_data
structure will be freed. However, this data structure is used for
completion notification after the restart is completed, which leads
to a UAF bug.
This results in a KFENCE bug notice.
BUG: KFENCE: use-after-free read in adf_device_reset_worker+0x38/0xa0 [intel_qat]
Use-after-free read at 0x00000000bc56fddf (in kfence-#142):
adf_device_reset_worker+0x38/0xa0 [intel_qat]
process_one_work+0x173/0x340
To resolve this race condition, the memory associated to the container
of the work_struct is freed on the worker if the timeout expired,
otherwise on the function that schedules the worker.
The timeout detection can be done by checking if the caller is
still waiting for completion or not by using completion_done() function.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: don't read past the mfuart notifcation
In case the firmware sends a notification that claims it has more data
than it has, we will read past that was allocated for the notification.
Remove the print of the buffer, we won't see it by default. If needed,
we can see the content with tracing.
This was reported by KFENCE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: avoid potential underflow in qdisc_pkt_len_init() with UFO
After commit 7c6d2ecbda83 ("net: be more gentle about silly gso
requests coming from user") virtio_net_hdr_to_skb() had sanity check
to detect malicious attempts from user space to cook a bad GSO packet.
Then commit cf9acc90c80ec ("net: virtio_net_hdr_to_skb: count
transport header in UFO") while fixing one issue, allowed user space
to cook a GSO packet with the following characteristic :
IPv4 SKB_GSO_UDP, gso_size=3, skb->len = 28.
When this packet arrives in qdisc_pkt_len_init(), we end up
with hdr_len = 28 (IPv4 header + UDP header), matching skb->len
Then the following sets gso_segs to 0 :
gso_segs = DIV_ROUND_UP(skb->len - hdr_len,
shinfo->gso_size);
Then later we set qdisc_skb_cb(skb)->pkt_len to back to zero :/
qdisc_skb_cb(skb)->pkt_len += (gso_segs - 1) * hdr_len;
This leads to the following crash in fq_codel [1]
qdisc_pkt_len_init() is best effort, we only want an estimation
of the bytes sent on the wire, not crashing the kernel.
This patch is fixing this particular issue, a following one
adds more sanity checks for another potential bug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: handle chunk tree lookup error in btrfs_relocate_sys_chunks()
The unhandled case in btrfs_relocate_sys_chunks() loop is a corruption,
as it could be caused only by two impossible conditions:
- at first the search key is set up to look for a chunk tree item, with
offset -1, this is an inexact search and the key->offset will contain
the correct offset upon a successful search, a valid chunk tree item
cannot have an offset -1
- after first successful search, the found_key corresponds to a chunk
item, the offset is decremented by 1 before the next loop, it's
impossible to find a chunk item there due to alignment and size
constraints

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm thin: make get_first_thin use rcu-safe list first function
The documentation in rculist.h explains the absence of list_empty_rcu()
and cautions programmers against relying on a list_empty() ->
list_first() sequence in RCU safe code. This is because each of these
functions performs its own READ_ONCE() of the list head. This can lead
to a situation where the list_empty() sees a valid list entry, but the
subsequent list_first() sees a different view of list head state after a
modification.
In the case of dm-thin, this author had a production box crash from a GP
fault in the process_deferred_bios path. This function saw a valid list
head in get_first_thin() but when it subsequently dereferenced that and
turned it into a thin_c, it got the inside of the struct pool, since the
list was now empty and referring to itself. The kernel on which this
occurred printed both a warning about a refcount_t being saturated, and
a UBSAN error for an out-of-bounds cpuid access in the queued spinlock,
prior to the fault itself. When the resulting kdump was examined, it
was possible to see another thread patiently waiting in thin_dtr's
synchronize_rcu.
The thin_dtr call managed to pull the thin_c out of the active thins
list (and have it be the last entry in the active_thins list) at just
the wrong moment which lead to this crash.
Fortunately, the fix here is straight forward. Switch get_first_thin()
function to use list_first_or_null_rcu() which performs just a single
READ_ONCE() and returns NULL if the list is already empty.
This was run against the devicemapper test suite's thin-provisioning
suites for delete and suspend and no regressions were observed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cpu: Re-enable CPU mitigations by default for !X86 architectures
Rename x86's to CPU_MITIGATIONS, define it in generic code, and force it
on for all architectures exception x86. A recent commit to turn
mitigations off by default if SPECULATION_MITIGATIONS=n kinda sorta
missed that "cpu_mitigations" is completely generic, whereas
SPECULATION_MITIGATIONS is x86-specific.
Rename x86's SPECULATIVE_MITIGATIONS instead of keeping both and have it
select CPU_MITIGATIONS, as having two configs for the same thing is
unnecessary and confusing. This will also allow x86 to use the knob to
manage mitigations that aren't strictly related to speculative
execution.
Use another Kconfig to communicate to common code that CPU_MITIGATIONS
is already defined instead of having x86's menu depend on the common
CPU_MITIGATIONS. This allows keeping a single point of contact for all
of x86's mitigations, and it's not clear that other architectures *want*
to allow disabling mitigations at compile-time.

Summary
In the Linux kernel, the following vulnerability has been resolved:
igb: Do not bring the device up after non-fatal error
Commit 004d25060c78 ("igb: Fix igb_down hung on surprise removal")
changed igb_io_error_detected() to ignore non-fatal pcie errors in order
to avoid hung task that can happen when igb_down() is called multiple
times. This caused an issue when processing transient non-fatal errors.
igb_io_resume(), which is called after igb_io_error_detected(), assumes
that device is brought down by igb_io_error_detected() if the interface
is up. This resulted in panic with stacktrace below.

To fix this issue igb_io_resume() checks if the interface is running and
the device is not down this means igb_io_error_detected() did not bring
the device down and there is no need to bring it up.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv4: check for NULL idev in ip_route_use_hint()
syzbot was able to trigger a NULL deref in fib_validate_source()
in an old tree [1].
It appears the bug exists in latest trees.
All calls to __in_dev_get_rcu() must be checked for a NULL result.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Properly link new fs rules into the tree
Previously, add_rule_fg would only add newly created rules from the
handle into the tree when they had a refcount of 1. On the other hand,
create_flow_handle tries hard to find and reference already existing
identical rules instead of creating new ones.
These two behaviors can result in a situation where create_flow_handle
1) creates a new rule and references it, then
2) in a subsequent step during the same handle creation references it
again,
resulting in a rule with a refcount of 2 that is not linked into the
tree, will have a NULL parent and root and will result in a crash when
the flow group is deleted because del_sw_hw_rule, invoked on rule
deletion, assumes node->parent is != NULL.
This happened in the wild, due to another bug related to incorrect
handling of duplicate pkt_reformat ids, which lead to the code in
create_flow_handle incorrectly referencing a just-added rule in the same
flow handle, resulting in the problem described above. Full details are
at [1].
This patch changes add_rule_fg to add new rules without parents into
the tree, properly initializing them and avoiding the crash. This makes
it more consistent with how rules are added to an FTE in
create_flow_handle.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xdp: fix invalid wait context of page_pool_destroy()
If the driver uses a page pool, it creates a page pool with
page_pool_create().
The reference count of page pool is 1 as default.
A page pool will be destroyed only when a reference count reaches 0.
page_pool_destroy() is used to destroy page pool, it decreases a
reference count.
When a page pool is destroyed, ->disconnect() is called, which is
mem_allocator_disconnect().
This function internally acquires mutex_lock().
If the driver uses XDP, it registers a memory model with
xdp_rxq_info_reg_mem_model().
The xdp_rxq_info_reg_mem_model() internally increases a page pool
reference count if a memory model is a page pool.
Now the reference count is 2.
To destroy a page pool, the driver should call both page_pool_destroy()
and xdp_unreg_mem_model().
The xdp_unreg_mem_model() internally calls page_pool_destroy().
Only page_pool_destroy() decreases a reference count.
If a driver calls page_pool_destroy() then xdp_unreg_mem_model(), we
will face an invalid wait context warning.
Because xdp_unreg_mem_model() calls page_pool_destroy() with
rcu_read_lock().
The page_pool_destroy() internally acquires mutex_lock().
Splat looks like:

To fix this problem, it uses rhashtable_lookup_fast() instead of
rhashtable_lookup() with rcu_read_lock().
Using xa without rcu_read_lock() here is safe.
xa is freed by __xdp_mem_allocator_rcu_free() and this is called by
call_rcu() of mem_xa_remove().
The mem_xa_remove() is called by page_pool_destroy() if a reference
count reaches 0.
The xa is already protected by the reference count mechanism well in the
control plane.
So removing rcu_read_lock() for page_pool_destroy() is safe.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ethtool: check device is present when getting link settings
A sysfs reader can race with a device reset or removal, attempting to
read device state when the device is not actually present. eg:
[exception RIP: qed_get_current_link+17]
#8 [ffffb9e4f2907c48] qede_get_link_ksettings at ffffffffc07a994a [qede]
#9 [ffffb9e4f2907cd8] __rh_call_get_link_ksettings at ffffffff992b01a3
#10 [ffffb9e4f2907d38] __ethtool_get_link_ksettings at ffffffff992b04e4
#11 [ffffb9e4f2907d90] duplex_show at ffffffff99260300
#12 [ffffb9e4f2907e38] dev_attr_show at ffffffff9905a01c
#13 [ffffb9e4f2907e50] sysfs_kf_seq_show at ffffffff98e0145b
#14 [ffffb9e4f2907e68] seq_read at ffffffff98d902e3
#15 [ffffb9e4f2907ec8] vfs_read at ffffffff98d657d1
#16 [ffffb9e4f2907f00] ksys_read at ffffffff98d65c3f
#17 [ffffb9e4f2907f38] do_syscall_64 at ffffffff98a052fb
crash> struct net_device.state ffff9a9d21336000
state = 5,
state 5 is __LINK_STATE_START (0b1) and __LINK_STATE_NOCARRIER (0b100).
The device is not present, note lack of __LINK_STATE_PRESENT (0b10).
This is the same sort of panic as observed in commit 4224cfd7fb65
("net-sysfs: add check for netdevice being present to speed_show").
There are many other callers of __ethtool_get_link_ksettings() which
don't have a device presence check.
Move this check into ethtool to protect all callers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: handle 2x996 RU allocation in cfg80211_calculate_bitrate_he()
Currently NL80211_RATE_INFO_HE_RU_ALLOC_2x996 is not handled in
cfg80211_calculate_bitrate_he(), leading to below warning:
kernel: invalid HE MCS: bw:6, ru:6
kernel: WARNING: CPU: 0 PID: 2312 at net/wireless/util.c:1501 cfg80211_calculate_bitrate_he+0x22b/0x270 [cfg80211]
Fix it by handling 2x996 RU allocation in the same way as 160 MHz bandwidth.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: mmci: stm32: fix DMA API overlapping mappings warning
Turning on CONFIG_DMA_API_DEBUG_SG results in the following warning:
DMA-API: mmci-pl18x 48220000.mmc: cacheline tracking EEXIST,
overlapping mappings aren't supported
WARNING: CPU: 1 PID: 51 at kernel/dma/debug.c:568
add_dma_entry+0x234/0x2f4
Modules linked in:
CPU: 1 PID: 51 Comm: kworker/1:2 Not tainted 6.1.28 #1
Hardware name: STMicroelectronics STM32MP257F-EV1 Evaluation Board (DT)
Workqueue: events_freezable mmc_rescan

DMA API debug brings to light leaking dma-mappings as dma_map_sg and
dma_unmap_sg are not correctly balanced.
If an error occurs in mmci_cmd_irq function, only mmci_dma_error
function is called and as this API is not managed on stm32 variant,
dma_unmap_sg is never called in this error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix shift-out-of-bounds in dctcp_update_alpha().
In dctcp_update_alpha(), we use a module parameter dctcp_shift_g
as follows:
alpha -= min_not_zero(alpha, alpha >> dctcp_shift_g);
...
delivered_ce <<= (10 - dctcp_shift_g);
It seems syzkaller started fuzzing module parameters and triggered
shift-out-of-bounds [0] by setting 100 to dctcp_shift_g:
memcpy((void*)0x20000080,
"/sys/module/tcp_dctcp/parameters/dctcp_shift_g\000", 47);
res = syscall(__NR_openat, /*fd=*/0xffffffffffffff9cul, /*file=*/0x20000080ul,
/*flags=*/2ul, /*mode=*/0ul);
memcpy((void*)0x20000000, "100\000", 4);
syscall(__NR_write, /*fd=*/r[0], /*val=*/0x20000000ul, /*len=*/4ul);
Let's limit the max value of dctcp_shift_g by param_set_uint_minmax().
With this patch:
# echo 10 > /sys/module/tcp_dctcp/parameters/dctcp_shift_g
# cat /sys/module/tcp_dctcp/parameters/dctcp_shift_g
10
# echo 11 > /sys/module/tcp_dctcp/parameters/dctcp_shift_g
-bash: echo: write error: Invalid argument
[0]:

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: avoid OOB when system.data xattr changes underneath the filesystem
When looking up for an entry in an inlined directory, if e_value_offs is
changed underneath the filesystem by some change in the block device, it
will lead to an out-of-bounds access that KASAN detects as an UAF.
EXT4-fs (loop0): mounted filesystem 00000000-0000-0000-0000-000000000000 r/w without journal. Quota mode: none.
loop0: detected capacity change from 2048 to 2047

Calling ext4_xattr_ibody_find right after reading the inode with
ext4_get_inode_loc will lead to a check of the validity of the xattrs,
avoiding this problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wireguard: netlink: check for dangling peer via is_dead instead of empty list
If all peers are removed via wg_peer_remove_all(), rather than setting
peer_list to empty, the peer is added to a temporary list with a head on
the stack of wg_peer_remove_all(). If a netlink dump is resumed and the
cursored peer is one that has been removed via wg_peer_remove_all(), it
will iterate from that peer and then attempt to dump freed peers.
Fix this by instead checking peer->is_dead, which was explictly created
for this purpose. Also move up the device_update_lock lockdep assertion,
since reading is_dead relies on that.
It can be reproduced by a small script like:
echo "Setting config..."
ip link add dev wg0 type wireguard
wg setconf wg0 /big-config
(
while true; do
echo "Showing config..."
wg showconf wg0 > /dev/null
done
) &
sleep 4
wg setconf wg0 <(printf "[Peer]\nPublicKey=$(wg genkey)\n")
Resulting in:

Summary
In the Linux kernel, the following vulnerability has been resolved:
slip: make slhc_remember() more robust against malicious packets
syzbot found that slhc_remember() was missing checks against
malicious packets [1].
slhc_remember() only checked the size of the packet was at least 20,
which is not good enough.
We need to make sure the packet includes the IPv4 and TCP header
that are supposed to be carried.
Add iph and th pointers to make the code more readable.
[1]

Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix warning during rehash
As previously explained, the rehash delayed work migrates filters from
one region to another. This is done by iterating over all chunks (all
the filters with the same priority) in the region and in each chunk
iterating over all the filters.
When the work runs out of credits it stores the current chunk and entry
as markers in the per-work context so that it would know where to resume
the migration from the next time the work is scheduled.
Upon error, the chunk marker is reset to NULL, but without resetting the
entry markers despite being relative to it. This can result in migration
being resumed from an entry that does not belong to the chunk being
migrated. In turn, this will eventually lead to a chunk being iterated
over as if it is an entry. Because of how the two structures happen to
be defined, this does not lead to KASAN splats, but to warnings such as
[1].
Fix by creating a helper that resets all the markers and call it from
all the places the currently only reset the chunk marker. For good
measures also call it when starting a completely new rehash. Add a
warning to avoid future cases.

Add a\nwarning to avoid future cases.\n\n[1]\nWARNING: CPU: 7 PID: 1076 at drivers/net/ethernet/mellanox/mlxsw/core_acl_flex_keys.c:407 mlxsw_afk_encode+0x242/0x2f0\nModules linked in:\nCPU: 7 PID: 1076 Comm: kworker/7:24 Tainted: G W 6.9.0-rc3-custom-00880-g29e61d91b77b #29\nHardware name: Mellanox Technologies Ltd.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: don't wait for tx queues if firmware is dead
There is a WARNING in iwl_trans_wait_tx_queues_empty() (that was
recently converted from just a message), that can be hit if we
wait for TX queues to become empty after firmware died. Clearly,
we can't expect anything from the firmware after it's declared dead.
Don't call iwl_trans_wait_tx_queues_empty() in this case. While it could
be a good idea to stop the flow earlier, the flush functions do some
maintenance work that is not related to the firmware, so keep that part
of the code running even when the firmware is not running.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_core: Fix possible buffer overflow
struct hci_dev_info has a fixed size name[8] field so in the event that
hdev->name is bigger than that strcpy would attempt to write past its
size, so this fixes this problem by switching to use strscpy.

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: core: check uartclk for zero to avoid divide by zero
Calling ioctl TIOCSSERIAL with an invalid baud_base can
result in uartclk being zero, which will result in a
divide by zero error in uart_get_divisor(). The check for
uartclk being zero in uart_set_info() needs to be done
before other settings are made as subsequent calls to
ioctl TIOCSSERIAL for the same port would be impacted if
the uartclk check was done where uartclk gets set.
Oops: divide error: 0000 PREEMPT SMP KASAN PTI

Summary
In the Linux kernel, the following vulnerability has been resolved:
enic: Validate length of nl attributes in enic_set_vf_port
enic_set_vf_port assumes that the nl attribute IFLA_PORT_PROFILE
is of length PORT_PROFILE_MAX and that the nl attributes
IFLA_PORT_INSTANCE_UUID, IFLA_PORT_HOST_UUID are of length PORT_UUID_MAX.
These attributes are validated (in the function do_setlink in rtnetlink.c)
using the nla_policy ifla_port_policy. The policy defines IFLA_PORT_PROFILE
as NLA_STRING, IFLA_PORT_INSTANCE_UUID as NLA_BINARY and
IFLA_PORT_HOST_UUID as NLA_STRING. That means that the length validation
using the policy is for the max size of the attributes and not on exact
size so the length of these attributes might be less than the sizes that
enic_set_vf_port expects. This might cause an out of bands
read access in the memcpys of the data of these
attributes in enic_set_vf_port.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Use refcount_inc_not_zero() in tcp_twsk_unique().
Anderson Nascimento reported a use-after-free splat in tcp_twsk_unique()
with nice analysis.
Since commit ec94c2696f0b ("tcp/dccp: avoid one atomic operation for
timewait hashdance"), inet_twsk_hashdance() sets TIME-WAIT socket's
sk_refcnt after putting it into ehash and releasing the bucket lock.
Thus, there is a small race window where other threads could try to
reuse the port during connect() and call sock_hold() in tcp_twsk_unique()
for the TIME-WAIT socket with zero refcnt.
If that happens, the refcnt taken by tcp_twsk_unique() is overwritten
and sock_put() will cause underflow, triggering a real use-after-free
somewhere else.
To avoid the use-after-free, we need to use refcount_inc_not_zero() in
tcp_twsk_unique() and give up on reusing the port if it returns false.
[0]:
refcount_t: addition on 0; use-after-free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
quota: Fix potential NULL pointer dereference
Below race may cause NULL pointer dereference
P1 P2
dquot_free_inode quota_off
drop_dquot_ref
remove_dquot_ref
dquots = i_dquot(inode)
dquots = i_dquot(inode)
srcu_read_lock
dquots[cnt]) != NULL (1)
dquots[type] = NULL (2)
spin_lock(&dquots[cnt]->dq_dqb_lock) (3)
....
If dquot_free_inode(or other routines) checks inode's quota pointers (1)
before quota_off sets it to NULL(2) and use it (3) after that, NULL pointer
dereference will be triggered.
So let's fix it by using a temporary pointer to avoid this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: Fix race between namespace cleanup and gc in the list:set type
Lion Ackermann reported that there is a race condition between namespace cleanup
in ipset and the garbage collection of the list:set type. The namespace
cleanup can destroy the list:set type of sets while the gc of the set type is
waiting to run in rcu cleanup. The latter uses data from the destroyed set which
thus leads use after free. The patch contains the following parts:
- When destroying all sets, first remove the garbage collectors, then wait
if needed and then destroy the sets.
- Fix the badly ordered "wait then remove gc" for the destroy a single set
case.
- Fix the missing rcu locking in the list:set type in the userspace test
case.
- Use proper RCU list handlings in the list:set type.
The patch depends on c1193d9bbbd3 (netfilter: ipset: Add list flush to cancel_gc).

The namespace\ncleanup can destroy the list:set type of sets while the gc of the set type is\nwaiting to run in rcu cleanup.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netpoll: Fix race condition in netpoll_owner_active
KCSAN detected a race condition in netpoll:
BUG: KCSAN: data-race in net_rx_action / netpoll_send_skb
write (marked) to 0xffff8881164168b0 of 4 bytes by interrupt on cpu 10:
net_rx_action (./include/linux/netpoll.h:90 net/core/dev.c:6712 net/core/dev.c:6822)
<snip>
read to 0xffff8881164168b0 of 4 bytes by task 1 on cpu 2:
netpoll_send_skb (net/core/netpoll.c:319 net/core/netpoll.c:345 net/core/netpoll.c:393)
netpoll_send_udp (net/core/netpoll.c:?)
<snip>
value changed: 0x0000000a -> 0xffffffff
This happens because netpoll_owner_active() needs to check if the
current CPU is the owner of the lock, touching napi->poll_owner
non atomically. The ->poll_owner field contains the current CPU holding
the lock.
Use an atomic read to check if the poll owner is the current CPU.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry()
xattr in ocfs2 maybe 'non-indexed', which saved with additional space
requested. It's better to check if the memory is out of bound before
memcmp, although this possibility mainly comes from crafted poisonous
images.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: fully validate NFT_DATA_VALUE on store to data registers
register store validation for NFT_DATA_VALUE is conditional, however,
the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This
only requires a new helper function to infer the register type from the
set datatype so this conditional check can be removed. Otherwise,
pointer to chain object can be leaked through the registers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: Fix response handling in iwl_mvm_send_recovery_cmd()
1. The size of the response packet is not validated.
2. The response buffer is not freed.
Resolve these issues by switching to iwl_mvm_send_cmd_status(),
which handles both size validation and frees the buffer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jfs: Fix uninit-value access of new_ea in ea_buffer
syzbot reports that lzo1x_1_do_compress is using uninit-value:
=====================================================
BUG: KMSAN: uninit-value in lzo1x_1_do_compress+0x19f9/0x2510 lib/lzo/lzo1x_compress.c:178
...
Uninit was stored to memory at:
ea_put fs/jfs/xattr.c:639 [inline]
...
Local variable ea_buf created at:
__jfs_setxattr+0x5d/0x1ae0 fs/jfs/xattr.c:662
__jfs_xattr_set+0xe6/0x1f0 fs/jfs/xattr.c:934
=====================================================
The reason is ea_buf->new_ea is not initialized properly.
Fix this by using memset to empty its content at the beginning
in ea_get().

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: uinput - reject requests with unreasonable number of slots
When exercising uinput interface syzkaller may try setting up device
with a really large number of slots, which causes memory allocation
failure in input_mt_init_slots(). While this allocation failure is
handled properly and request is rejected, it results in syzkaller
reports. Additionally, such request may put undue burden on the
system which will try to free a lot of memory for a bogus request.
Fix it by limiting allowed number of slots to 100. This can easily
be extended if we see devices that can track more than 100 contacts.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: Do not use WQ_MEM_RECLAIM flag for workqueue
Issue reported by customer during SRIOV testing, call trace:
When both i40e and the i40iw driver are loaded, a warning
in check_flush_dependency is being triggered. This seems
to be because of the i40e driver workqueue is allocated with
the WQ_MEM_RECLAIM flag, and the i40iw one is not.
Similar error was encountered on ice too and it was fixed by
removing the flag. Do the same for i40e too.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cpumap: Zero-initialise xdp_rxq_info struct before running XDP program
When running an XDP program that is attached to a cpumap entry, we don't
initialise the xdp_rxq_info data structure being used in the xdp_buff
that backs the XDP program invocation. Tobias noticed that this leads to
random values being returned as the xdp_md->rx_queue_index value for XDP
programs running in a cpumap.
This means we're basically returning the contents of the uninitialised
memory, which is bad. Fix this by zero-initialising the rxq data
structure before running the XDP program.

Summary
In the Linux kernel, the following vulnerability has been resolved:
do_sys_name_to_handle(): use kzalloc() to fix kernel-infoleak
syzbot identified a kernel information leak vulnerability in
do_sys_name_to_handle() and issued the following report [1].

Memory access of size 20 starts at ffff888128a46380
Data copied to user address 0000000020000240"
Per Chuck Lever's suggestion, use kzalloc() instead of kmalloc() to
solve the problem.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV sockets
TCP_SYN_RECV state is really special, it is only used by
cross-syn connections, mostly used by fuzzers.
In the following crash [1], syzbot managed to trigger a divide
by zero in tcp_rcv_space_adjust()
A socket makes the following state transitions,
without ever calling tcp_init_transfer(),
meaning tcp_init_buffer_space() is also not called.
TCP_CLOSE
connect()
TCP_SYN_SENT
TCP_SYN_RECV
shutdown() -> tcp_shutdown(sk, SEND_SHUTDOWN)
TCP_FIN_WAIT1
To fix this issue, change tcp_shutdown() to not
perform a TCP_SYN_RECV -> TCP_FIN_WAIT1 transition,
which makes no sense anyway.
When tcp_rcv_state_process() later changes socket state
from TCP_SYN_RECV to TCP_ESTABLISH, then look at
sk->sk_shutdown to finally enter TCP_FIN_WAIT1 state,
and send a FIN packet from a sane socket state.
This means tcp_send_fin() can now be called from BH
context, and must use GFP_ATOMIC allocations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix OOBs when building SMB2_IOCTL request
When using encryption, either enforced by the server or when using
'seal' mount option, the client will squash all compound request buffers
down for encryption into a single iov in smb2_set_next_command().
SMB2_ioctl_init() allocates a small buffer (448 bytes) to hold the
SMB2_IOCTL request in the first iov, and if the user passes an input
buffer that is greater than 328 bytes, smb2_set_next_command() will
end up writing off the end of @rqst->iov[0].iov_base as shown below:
mount.cifs //srv/share /mnt -o ...,seal
ln -s $(perl -e "print('a')for 1..1024") /mnt/link

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: fix potential invalid pointer dereference in blk_add_partition
The blk_add_partition() function initially used a single if-condition
(IS_ERR(part)) to check for errors when adding a partition. This was
modified to handle the specific case of -ENXIO separately, allowing the
function to proceed without logging the error in this case. However,
this change unintentionally left a path where md_autodetect_dev()
could be called without confirming that part is a valid pointer.
This commit separates the error handling logic by splitting the
initial if-condition, improving code readability and handling specific
error scenarios explicitly. The function now distinguishes the general
error case from -ENXIO without altering the existing behavior of
md_autodetect_dev() calls.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: firewire-lib: Avoid division by zero in apply_constraint_to_size()
The step variable is initialized to zero. It is changed in the loop,
but if it's not changed it will remain zero. Add a variable check
before the division.
The observed behavior was introduced by commit 826b5de90c0b
("ALSA: firewire-lib: fix insufficient PCM rule for period/buffer size"),
and it is difficult to show that any of the interval parameters will
satisfy the snd_interval_test() condition with data from the
amdtp_rate_table[] table.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gtp: Destroy device along with udp socket's netns dismantle.
gtp_newlink() links the device to a list in dev_net(dev) instead of
src_net, where a udp tunnel socket is created.
Even when src_net is removed, the device stays alive on dev_net(dev).
Then, removing src_net triggers the splat below. [0]
In this example, gtp0 is created in ns2, and the udp socket is created
in ns1.
ip netns add ns1
ip netns add ns2
ip -n ns1 link add netns ns2 name gtp0 type gtp role sgsn
ip netns del ns1
Let's link the device to the socket's netns instead.
Now, gtp_net_exit_batch_rtnl() needs another netdev iteration to remove
all gtp devices in the netns.
[0]:

Summary
In the Linux kernel, the following vulnerability has been resolved:
tun: limit printing rate when illegal packet received by tun dev
vhost_worker will call tun call backs to receive packets. If too many
illegal packets arrives, tun_do_read will keep dumping packet contents.
When console is enabled, it will costs much more cpu time to dump
packet and soft lockup will be detected.
net_ratelimit mechanism can be used to limit the dumping rate.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/iwcm: Fix WARNING:at_kernel/workqueue.c:#check_flush_dependency
In the commit aee2424246f9 ("RDMA/iwcm: Fix a use-after-free related to
destroying CM IDs"), the function flush_workqueue is invoked to flush the
work queue iwcm_wq.
But at that time, the work queue iwcm_wq was created via the function
alloc_ordered_workqueue without the flag WQ_MEM_RECLAIM.
Because the current process is trying to flush the whole iwcm_wq, if
iwcm_wq doesn't have the flag WQ_MEM_RECLAIM, verify that the current
process is not reclaiming memory or running on a workqueue which doesn't
have the flag WQ_MEM_RECLAIM as that can break forward-progress guarantee
leading to a deadlock.
The call trace is as below:

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_payload: sanitize offset and length before calling skb_checksum()
If access to offset + length is larger than the skbuff length, then
skb_checksum() triggers BUG_ON().
skb_checksum() internally subtracts the length parameter while iterating
over skbuff, BUG_ON(len) at the end of it checks that the expected
length to be included in the checksum calculation is fully consumed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix garbage collector racing against connect()
Garbage collector does not take into account the risk of embryo getting
enqueued during the garbage collection. If such embryo has a peer that
carries SCM_RIGHTS, two consecutive passes of scan_children() may see a
different set of children. Leading to an incorrectly elevated inflight
count, and then a dangling pointer within the gc_inflight_list.
sockets are AF_UNIX/SOCK_STREAM
S is an unconnected socket
L is a listening in-flight socket bound to addr, not in fdtable
V's fd will be passed via sendmsg(), gets inflight count bumped
connect(S, addr) sendmsg(S, [V]); close(V) __unix_gc()
---------------- ------------------------- -----------
NS = unix_create1()
skb1 = sock_wmalloc(NS)
L = unix_find_other(addr)
unix_state_lock(L)
unix_peer(S) = NS
// V count=1 inflight=0
NS = unix_peer(S)
skb2 = sock_alloc()
skb_queue_tail(NS, skb2[V])
// V became in-flight
// V count=2 inflight=1
close(V)
// V count=1 inflight=1
// GC candidate condition met
for u in gc_inflight_list:
if (total_refs == inflight_refs)
add u to gc_candidates
// gc_candidates={L, V}
for u in gc_candidates:
scan_children(u, dec_inflight)
// embryo (skb1) was not
// reachable from L yet, so V's
// inflight remains unchanged
__skb_queue_tail(L, skb1)
unix_state_unlock(L)
for u in gc_candidates:
if (u.inflight)
scan_children(u, inc_inflight_move_tail)
// V count=1 inflight=2 (!)
If there is a GC-candidate listening socket, lock/unlock its state. This
makes GC wait until the end of any ongoing connect() to that socket. After
flipping the lock, a possibly SCM-laden embryo is already enqueued. And if
there is another embryo coming, it can not possibly carry SCM_RIGHTS. At
this point, unix_inflight() can not happen because unix_gc_lock is already
taken. Inflight graph remains unaffected.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netem: fix return value if duplicate enqueue fails
There is a bug in netem_enqueue() introduced by
commit 5845f706388a ("net: netem: fix skb length BUG_ON in __skb_to_sgvec")
that can lead to a use-after-free.
This commit made netem_enqueue() always return NET_XMIT_SUCCESS
when a packet is duplicated, which can cause the parent qdisc's q.qlen
to be mistakenly incremented. When this happens qlen_notify() may be
skipped on the parent during destruction, leaving a dangling pointer
for some classful qdiscs like DRR.
There are two ways for the bug happen:
- If the duplicated packet is dropped by rootq->enqueue() and then
the original packet is also dropped.
- If rootq->enqueue() sends the duplicated packet to a different qdisc
and the original packet is dropped.
In both cases NET_XMIT_SUCCESS is returned even though no packets
are enqueued at the netem qdisc.
The fix is to defer the enqueue of the duplicate packet until after
the original packet has been guaranteed to return NET_XMIT_SUCCESS.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: Fix suspicious rcu_dereference_protected()
When destroying all sets, we are either in pernet exit phase or
are executing a "destroy all sets command" from userspace. The latter
was taken into account in ip_set_dereference() (nfnetlink mutex is held),
but the former was not. The patch adds the required check to
rcu_dereference_protected() in ip_set_dereference().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: Fix infinite recursion in fib6_dump_done().
syzkaller reported infinite recursive calls of fib6_dump_done() during
netlink socket destruction. [1]
From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then
the response was generated. The following recvmmsg() resumed the dump
for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due
to the fault injection. [0]
12:01:34 executing program 3:
r0 = socket$nl_route(0x10, 0x3, 0x0)
sendmsg$nl_route(r0, ... snip ...)
recvmmsg(r0, ... snip ...) (fail_nth: 8)
Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call
of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped
receiving the response halfway through, and finally netlink_sock_destruct()
called nlk_sk(sk)->cb.done().
fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it
is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by
nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling
itself recursively and hitting the stack guard page.
To avoid the issue, let's set the destructor after kzalloc().

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Fix NFSv3 SETATTR/CREATE's handling of large file sizes
iattr::ia_size is a loff_t, so these NFSv3 procedures must be
careful to deal with incoming client size values that are larger
than s64_max without corrupting the value.
Silently capping the value results in storing a different value
than the client passed in which is unexpected behavior, so remove
the min_t() check in decode_sattr3().
Note that RFC 1813 permits only the WRITE procedure to return
NFS3ERR_FBIG. We believe that NFSv3 reference implementations
also return NFS3ERR_FBIG when ia_size is too large.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qedi: Fix crash while reading debugfs attribute
The qedi_dbg_do_not_recover_cmd_read() function invokes sprintf() directly
on a __user pointer, which results into the crash.
To fix this issue, use a small local stack buffer for sprintf() and then
call simple_read_from_buffer(), which in turns make the copy_to_user()
call.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: sg: Fix slab-use-after-free read in sg_release()
Fix a use-after-free bug in sg_release(), detected by syzbot with KASAN:
BUG: KASAN: slab-use-after-free in lock_release+0x151/0xa30
kernel/locking/lockdep.c:5838
__mutex_unlock_slowpath+0xe2/0x750 kernel/locking/mutex.c:912
sg_release+0x1f4/0x2e0 drivers/scsi/sg.c:407
In sg_release(), the function kref_put(&sfp->f_ref, sg_remove_sfp) is
called before releasing the open_rel_lock mutex. The kref_put() call may
decrement the reference count of sfp to zero, triggering its cleanup
through sg_remove_sfp(). This cleanup includes scheduling deferred work
via sg_remove_sfp_usercontext(), which ultimately frees sfp.
After kref_put(), sg_release() continues to unlock open_rel_lock and may
reference sfp or sdp. If sfp has already been freed, this results in a
slab-use-after-free error.
Move the kref_put(&sfp->f_ref, sg_remove_sfp) call after unlocking the
open_rel_lock mutex. This ensures:
- No references to sfp or sdp occur after the reference count is
decremented.
- Cleanup functions such as sg_remove_sfp() and
sg_remove_sfp_usercontext() can safely execute without impacting the
mutex handling in sg_release().
The fix has been tested and validated by syzbot. This patch closes the
bug reported at the following syzkaller link and ensures proper
sequencing of resource cleanup and mutex operations, eliminating the
risk of use-after-free errors in sg_release().

Summary
In the Linux kernel, the following vulnerability has been resolved:
md: fix resync softlockup when bitmap size is less than array size
Is is reported that for dm-raid10, lvextend + lvchange --syncaction will
trigger following softlockup:
kernel:watchdog: BUG: soft lockup - CPU#3 stuck for 26s! [mdX_resync:6976]
CPU: 7 PID: 3588 Comm: mdX_resync Kdump: loaded Not tainted 6.9.0-rc4-next-20240419 #1
RIP: 0010:_raw_spin_unlock_irq+0x13/0x30
Call Trace:
<TASK>
md_bitmap_start_sync+0x6b/0xf0
raid10_sync_request+0x25c/0x1b40 [raid10]
md_do_sync+0x64b/0x1020
md_thread+0xa7/0x170
kthread+0xcf/0x100
ret_from_fork+0x30/0x50
ret_from_fork_asm+0x1a/0x30
And the detailed process is as follows:
md_do_sync
j = mddev->resync_min
while (j < max_sectors)
sectors = raid10_sync_request(mddev, j, &skipped)
if (!md_bitmap_start_sync(..., &sync_blocks))
// md_bitmap_start_sync set sync_blocks to 0
return sync_blocks + sectors_skippe;
// sectors = 0;
j += sectors;
// j never change
Root cause is that commit 301867b1c168 ("md/raid10: check
slab-out-of-bounds in md_bitmap_get_counter") return early from
md_bitmap_get_counter(), without setting returned blocks.
Fix this problem by always set returned blocks from
md_bitmap_get_counter"(), as it used to be.
Noted that this patch just fix the softlockup problem in kernel, the
case that bitmap size doesn't match array size still need to be fixed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/aio: Check IOCB_AIO_RW before the struct aio_kiocb conversion
The first kiocb_set_cancel_fn() argument may point at a struct kiocb
that is not embedded inside struct aio_kiocb. With the current code,
depending on the compiler, the req->ki_ctx read happens either before
the IOCB_AIO_RW test or after that test. Move the req->ki_ctx read such
that it is guaranteed that the IOCB_AIO_RW test happens first.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm array: fix releasing a faulty array block twice in dm_array_cursor_end
When dm_bm_read_lock() fails due to locking or checksum errors, it
releases the faulty block implicitly while leaving an invalid output
pointer behind. The caller of dm_bm_read_lock() should not operate on
this invalid dm_block pointer, or it will lead to undefined result.
For example, the dm_array_cursor incorrectly caches the invalid pointer
on reading a faulty array block, causing a double release in
dm_array_cursor_end(), then hitting the BUG_ON in dm-bufio cache_put().
Reproduce steps:
1. initialize a cache device
dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"
dmsetup create corig --table "0 524288 linear /dev/sdc $262144"
dd if=/dev/zero of=/dev/mapper/cmeta bs=4k count=1
dmsetup create cache --table "0 524288 cache /dev/mapper/cmeta \
/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
2. wipe the second array block offline
dmsteup remove cache cmeta cdata corig
mapping_root=$(dd if=/dev/sdc bs=1c count=8 skip=192 \
2>/dev/null | hexdump -e '1/8 "%u\n"')
ablock=$(dd if=/dev/sdc bs=1c count=8 skip=$((4096*mapping_root+2056)) \
2>/dev/null | hexdump -e '1/8 "%u\n"')
dd if=/dev/zero of=/dev/sdc bs=4k count=1 seek=$ablock
3. try reopen the cache device
dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"
dmsetup create corig --table "0 524288 linear /dev/sdc $262144"
dmsetup create cache --table "0 524288 cache /dev/mapper/cmeta \
/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
Kernel logs:
(snip)
device-mapper: array: array_block_check failed: blocknr 0 != wanted 10
device-mapper: block manager: array validator check failed for block 10
device-mapper: array: get_ablock failed
device-mapper: cache metadata: dm_array_cursor_next for mapping failed
------------[ cut here ]------------
kernel BUG at drivers/md/dm-bufio.c:638!
Fix by setting the cached block pointer to NULL on errors.
In addition to the reproducer described above, this fix can be
verified using the "array_cursor/damaged" test in dm-unit:
dm-unit run /pdata/array_cursor/damaged --kernel-dir <KERNEL_DIR>

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: flush pending destroy work before exit_net release
Similar to 2c9f0293280e ("netfilter: nf_tables: flush pending destroy
work before netlink notifier") to address a race between exit_net and
the destroy workqueue.
The trace below shows an element to be released via destroy workqueue
while exit_net path (triggered via module removal) has already released
the set that is used in such transaction.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix possible memory leak in lpfc_rcv_padisc()
The call to lpfc_sli4_resume_rpi() in lpfc_rcv_padisc() may return an
unsuccessful status. In such cases, the elsiocb is not issued, the
completion is not called, and thus the elsiocb resource is leaked.
Check return value after calling lpfc_sli4_resume_rpi() and conditionally
release the elsiocb resource.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: usbtv: Remove useless locks in usbtv_video_free()
Remove locks calls in usbtv_video_free() because
are useless and may led to a deadlock as reported here:
https://syzkaller.appspot.com/x/bisect.txt?x=166dc872180000
Also remove usbtv_stop() call since it will be called when
unregistering the device.
Before 'c838530d230b' this issue would only be noticed if you
disconnect while streaming and now it is noticeable even when
disconnecting while not streaming.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ena: Fix incorrect descriptor free behavior
ENA has two types of TX queues:
- queues which only process TX packets arriving from the network stack
- queues which only process TX packets forwarded to it by XDP_REDIRECT
or XDP_TX instructions
The ena_free_tx_bufs() cycles through all descriptors in a TX queue
and unmaps + frees every descriptor that hasn't been acknowledged yet
by the device (uncompleted TX transactions).
The function assumes that the processed TX queue is necessarily from
the first category listed above and ends up using napi_consume_skb()
for descriptors belonging to an XDP specific queue.
This patch solves a bug in which, in case of a VF reset, the
descriptors aren't freed correctly, leading to crashes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path
The commit mutex should not be released during the critical section
between nft_gc_seq_begin() and nft_gc_seq_end(), otherwise, async GC
worker could collect expired objects and get the released commit lock
within the same GC sequence.
nf_tables_module_autoload() temporarily releases the mutex to load
module dependencies, then it goes back to replay the transaction again.
Move it at the end of the abort phase after nft_gc_seq_end() is called.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gt: Reset queue_priority_hint on parking
Originally, with strict in order execution, we could complete execution
only when the queue was empty. Preempt-to-busy allows replacement of an
active request that may complete before the preemption is processed by
HW. If that happens, the request is retired from the queue, but the
queue_priority_hint remains set, preventing direct submission until
after the next CS interrupt is processed.
This preempt-to-busy race can be triggered by the heartbeat, which will
also act as the power-management barrier and upon completion allow us to
idle the HW. We may process the completion of the heartbeat, and begin
parking the engine before the CS event that restores the
queue_priority_hint, causing us to fail the assertion that it is MIN.

If that happens, the request is retired from the queue, but the\nqueue_priority_hint remains set, preventing direct submission until\nafter the next CS interrupt is processed.\n\nThis preempt-to-busy race can be triggered by the heartbeat, which will\nalso act as the power-management barrier and upon completion allow us to\nidle the HW.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: cancel nfsd_shrinker_work using sync mode in nfs4_state_shutdown_net
In the normal case, when we excute `echo 0 > /proc/fs/nfsd/threads`, the
function `nfs4_state_destroy_net` in `nfs4_state_shutdown_net` will
release all resources related to the hashed `nfs4_client`. If the
`nfsd_client_shrinker` is running concurrently, the `expire_client`
function will first unhash this client and then destroy it. This can
lead to the following warning. Additionally, numerous use-after-free
errors may occur as well.
nfsd_client_shrinker echo 0 > /proc/fs/nfsd/threads

Summary
In the Linux kernel, the following vulnerability has been resolved:
aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts
This patch is against CVE-2023-6270. The description of cve is:
A flaw was found in the ATA over Ethernet (AoE) driver in the Linux
kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on
`struct net_device`, and a use-after-free can be triggered by racing
between the free on the struct and the access through the `skbtxq`
global queue. This could lead to a denial of service condition or
potential code execution.
In aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial
code is finished. But the net_device ifp will still be used in
later tx()->dev_queue_xmit() in kthread. Which means that the
dev_put(ifp) should NOT be called in the success path of skb
initial code in aoecmd_cfg_pkts(). Otherwise tx() may run into
use-after-free because the net_device is freed.
This patch removed the dev_put(ifp) in the success path in
aoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx().

The description of cve is:\n\n A flaw was found in the ATA over Ethernet (AoE) driver in the Linux\n kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on\n `struct net_device`, and a use-after-free can be triggered by racing\n between the free on the struct and the access through the `skbtxq`\n global queue. This could lead to a denial of service condition or\n potential code execution.\n\nIn aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial\ncode is finished. But the net_device ifp will still be used in\nlater tx()-\u003edev_queue_xmit() in kthread. Which means that the\ndev_put(ifp) should NOT be called in the success path of skb\ninitial code in aoecmd_cfg_pkts(). Otherwise tx() may run into\nuse-after-free because the net_device is freed.\n\nThis patch removed the dev_put(ifp) in the success path in\naoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx()."

CWE
- CWE-476 - NULL Pointer Dereference
Summary
Issue summary: Processing a maliciously formatted PKCS12 file may lead OpenSSL
to crash leading to a potential Denial of Service attack
Impact summary: Applications loading files in the PKCS12 format from untrusted
sources might terminate abruptly.
A file in PKCS12 format can contain certificates and keys and may come from an
untrusted source. The PKCS12 specification allows certain fields to be NULL, but
OpenSSL does not correctly check for this case. This can lead to a NULL pointer
dereference that results in OpenSSL crashing. If an application processes PKCS12
files from an untrusted source using the OpenSSL APIs then that application will
be vulnerable to this issue.
OpenSSL APIs that are vulnerable to this are: PKCS12_parse(),
PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes()
and PKCS12_newpass().
We have also fixed a similar issue in SMIME_write_PKCS7(). However since this
function is related to writing data we do not consider it security significant.
The FIPS modules in 3.2, 3.1 and 3.0 are not affected by this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: Fix potential data-race in __nft_flowtable_type_get()
nft_unregister_flowtable_type() within nf_flow_inet_module_exit() can
concurrent with __nft_flowtable_type_get() within nf_tables_newflowtable().
And thhere is not any protection when iterate over nf_tables_flowtables
list in __nft_flowtable_type_get(). Therefore, there is pertential
data-race of nf_tables_flowtables list entry.
Use list_for_each_entry_rcu() to iterate over nf_tables_flowtables list
in __nft_flowtable_type_get(), and use rcu_read_lock() in the caller
nft_flowtable_type_get() to protect the entire type query process.

Summary
In the Linux kernel, the following vulnerability has been resolved:
batman-adv: Avoid infinite loop trying to resize local TT
If the MTU of one of an attached interface becomes too small to transmit
the local translation table then it must be resized to fit inside all
fragments (when enabled) or a single packet.
But if the MTU becomes too low to transmit even the header + the VLAN
specific part then the resizing of the local TT will never succeed. This
can for example happen when the usable space is 110 bytes and 11 VLANs are
on top of batman-adv. In this case, at least 116 byte would be needed.
There will just be an endless spam of
batman_adv: batadv0: Forced to purge local tt entries to fit new maximum fragment MTU (110)
in the log but the function will never finish. Problem here is that the
timeout will be halved all the time and will then stagnate at 0 and
therefore never be able to reduce the table even more.
There are other scenarios possible with a similar result. The number of
BATADV_TT_CLIENT_NOPURGE entries in the local TT can for example be too
high to fit inside a packet. Such a scenario can therefore happen also with
only a single VLAN + 7 non-purgable addresses - requiring at least 120
bytes.
While this should be handled proactively when:
* interface with too low MTU is added
* VLAN is added
* non-purgeable local mac is added
* MTU of an attached interface is reduced
* fragmentation setting gets disabled (which most likely requires dropping
attached interfaces)
not all of these scenarios can be prevented because batman-adv is only
consuming events without the the possibility to prevent these actions
(non-purgable MAC address added, MTU of an attached interface is reduced).
It is therefore necessary to also make sure that the code is able to handle
also the situations when there were already incompatible system
configuration are present.

Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: core: delete incorrect free in pinctrl_enable()
The "pctldev" struct is allocated in devm_pinctrl_register_and_init().
It's a devm_ managed pointer that is freed by devm_pinctrl_dev_release(),
so freeing it in pinctrl_enable() will lead to a double free.
The devm_pinctrl_dev_release() function frees the pindescs and destroys
the mutex as well.

CWE
- CWE-416 - Use After Free
Summary
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
The function nft_pipapo_walk did not skip inactive elements during set walk which could lead double deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-after-free.
We recommend upgrading past commit 317eb9685095678f2c9f5a8189de698c5354316a.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix index out of bounds in degamma hardware format translation
Fixes index out of bounds issue in
`cm_helper_translate_curve_to_degamma_hw_format` function. The issue
could occur when the index 'i' exceeds the number of transfer function
points (TRANSFER_FUNC_POINTS).
The fix adds a check to ensure 'i' is within bounds before accessing the
transfer function points. If 'i' is out of bounds the function returns
false to indicate an error.
Reported by smatch:

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4.2: fix nfs4_listxattr kernel BUG at mm/usercopy.c:102
A call to listxattr() with a buffer size = 0 returns the actual
size of the buffer needed for a subsequent call. When size > 0,
nfs4_listxattr() does not return an error because either
generic_listxattr() or nfs4_listxattr_nfs4_label() consumes
exactly all the bytes then size is 0 when calling

Issue is reproduced when generic_listxattr() returns 'system.nfs4_acl',
thus calling lisxattr() with size = 16 will trigger the bug.
Add check on nfs4_listxattr() to return ERANGE error when it is
called with size > 0 and the return value is greater than size.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_fs: Remove WARN_ON in functionfs_bind
This commit addresses an issue related to below kernel panic where
panic_on_warn is enabled. It is caused by the unnecessary use of WARN_ON
in functionsfs_bind, which easily leads to the following scenarios.
1.adb_write in adbd 2. UDC write via configfs
================= =====================
->usb_ffs_open_thread() ->UDC write
->open_functionfs() ->configfs_write_iter()
->adb_open() ->gadget_dev_desc_UDC_store()
->adb_write() ->usb_gadget_register_driver_owner
->driver_register()
->StartMonitor() ->bus_add_driver()
->adb_read() ->gadget_bind_driver()
<times-out without BIND event> ->configfs_composite_bind()
->usb_add_function()
->open_functionfs() ->ffs_func_bind()
->adb_open() ->functionfs_bind()
<ffs->state !=FFS_ACTIVE>
The adb_open, adb_read, and adb_write operations are invoked from the
daemon, but trying to bind the function is a process that is invoked by
UDC write through configfs, which opens up the possibility of a race
condition between the two paths. In this race scenario, the kernel panic
occurs due to the WARN_ON from functionfs_bind when panic_on_warn is
enabled. This commit fixes the kernel panic by removing the unnecessary
WARN_ON.
Kernel panic - not syncing: kernel: panic_on_warn set ...

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: sr: fix memleak in seg6_hmac_init_algo
seg6_hmac_init_algo returns without cleaning up the previous allocations
if one fails, so it's going to leak all that memory and the crypto tfms.
Update seg6_hmac_exit to only free the memory when allocated, so we can
reuse the code directly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: check dot and dotdot of dx_root before making dir indexed
Syzbot reports a issue as follows:

============================================
The immediate cause of this problem is that there is only one valid dentry
for the block to be split during do_split, so split==0 results in out of
bounds accesses to the map triggering the issue.
do_split
unsigned split
dx_make_map
count = 1
split = count/2 = 0;
continued = hash2 == map[split - 1].hash;
---> map[4294967295]
The maximum length of a filename is 255 and the minimum block size is 1024,
so it is always guaranteed that the number of entries is greater than or
equal to 2 when do_split() is called.
But syzbot's crafted image has no dot and dotdot in dir, and the dentry
distribution in dirblock is as follows:
bus dentry1 hole dentry2 free
|xx--|xx-------------|...............|xx-------------|...............|
0 12 (8+248)=256 268 256 524 (8+256)=264 788 236 1024
So when renaming dentry1 increases its name_len length by 1, neither hole
nor free is sufficient to hold the new dentry, and make_indexed_dir() is
called.
In make_indexed_dir() it is assumed that the first two entries of the
dirblock must be dot and dotdot, so bus and dentry1 are left in dx_root
because they are treated as dot and dotdot, and only dentry2 is moved
to the new leaf block. That's why count is equal to 1.
Therefore add the ext4_check_dx_root() helper function to add more sanity
checks to dot and dotdot before starting the conversion to avoid the above
issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-mem2mem: fix a memleak in v4l2_m2m_register_entity
The entity->name (i.e. name) is allocated in v4l2_m2m_register_entity
but isn't freed in its following error-handling paths. This patch
adds such deallocation to prevent memleak of entity->name.

Summary
In the Linux kernel, the following vulnerability has been resolved:
soundwire: cadence: fix invalid PDI offset
For some reason, we add an offset to the PDI, presumably to skip the
PDI0 and PDI1 which are reserved for BPT.
This code is however completely wrong and leads to an out-of-bounds
access. We were just lucky so far since we used only a couple of PDIs
and remained within the PDI array bounds.
A Fixes: tag is not provided since there are no known platforms where
the out-of-bounds would be accessed, and the initial code had problems
as well.
A follow-up patch completely removes this useless offset.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: return -EINVAL when namelen is 0
When we have a corrupted main.sqlite in /var/lib/nfs/nfsdcld/, it may
result in namelen being 0, which will cause memdup_user() to return
ZERO_SIZE_PTR.
When we access the name.data that has been assigned the value of
ZERO_SIZE_PTR in nfs4_client_to_reclaim(), null pointer dereference is
triggered.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: fix NULL dereference in nfs3svc_encode_getaclres
In error cases the dentry may be NULL.
Before 20798dfe249a, the encoder also checked dentry and
d_really_is_positive(dentry), but that looks like overkill to me--zero
status should be enough to guarantee a positive dentry.
This isn't the first time we've seen an error-case NULL dereference
hidden in the initialization of a local variable in an xdr encoder. But
I went back through the other recent rewrites and didn't spot any
similar bugs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4: Prevent NULL-pointer dereference in nfs42_complete_copies()
On the node of an NFS client, some files saved in the mountpoint of the
NFS server were copied to another location of the same NFS server.
Accidentally, the nfs42_complete_copies() got a NULL-pointer dereference
crash with the following syslog:
[232064.838881] NFSv4: state recovery failed for open file nfs/pvc-12b5200d-cd0f-46a3-b9f0-af8f4fe0ef64.qcow2, error = -116

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: phy: fix phy_get_internal_delay accessing an empty array
The phy_get_internal_delay function could try to access to an empty
array in the case that the driver is calling phy_get_internal_delay
without defining delay_values and rx-internal-delay-ps or
tx-internal-delay-ps is defined to 0 in the device-tree.
This will lead to "unable to handle kernel NULL pointer dereference at
virtual address 0". To avoid this kernel oops, the test should be delay
>= 0. As there is already delay < 0 test just before, the test could
only be size == 0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_packet: fix vlan_get_tci() vs MSG_PEEK
Blamed commit forgot MSG_PEEK case, allowing a crash [1] as found
by syzbot.
Rework vlan_get_tci() to not touch skb at all,
so that it can be used from many cpus on the same skb.
Add a const qualifier to skb argument.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gem: Fix Virtual Memory mapping boundaries calculation
Calculating the size of the mapped area as the lesser value
between the requested size and the actual size does not consider
the partial mapping offset. This can cause page fault access.
Fix the calculation of the starting and ending addresses, the
total size is now deduced from the difference between the end and
start addresses.
Additionally, the calculations have been rewritten in a clearer
and more understandable form.
[Joonas: Add Requires: tag]
Requires: 60a2066c5005 ("drm/i915/gem: Adjust vma offset for framebuffer mmap offset")
(cherry picked from commit 97b6784753da06d9d40232328efc5c5367e53417)

Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: devicetree: fix refcount leak in pinctrl_dt_to_map()
If we fail to allocate propname buffer, we need to drop the reference
count we just took. Because the pinctrl_dt_free_maps() includes the
droping operation, here we call it directly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dma-buf/sw-sync: don't enable IRQ from sync_print_obj()
Since commit a6aa8fca4d79 ("dma-buf/sw-sync: Reduce irqsave/irqrestore from
known context") by error replaced spin_unlock_irqrestore() with
spin_unlock_irq() for both sync_debugfs_show() and sync_print_obj() despite
sync_print_obj() is called from sync_debugfs_show(), lockdep complains
inconsistent lock state warning.
Use plain spin_{lock,unlock}() for sync_print_obj(), for
sync_debugfs_show() is already using spin_{lock,unlock}_irq().

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: discard table flag update with pending basechain deletion
Hook unregistration is deferred to the commit phase, same occurs with
hook updates triggered by the table dormant flag. When both commands are
combined, this results in deleting a basechain while leaving its hook
still registered in the core.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netrom: Fix a memory leak in nr_heartbeat_expiry()
syzbot reported a memory leak in nr_create() [0].
Commit 409db27e3a2e ("netrom: Fix use-after-free of a listening socket.")
added sock_hold() to the nr_heartbeat_expiry() function, where
a) a socket has a SOCK_DESTROY flag or
b) a listening socket has a SOCK_DEAD flag.
But in the case "a," when the SOCK_DESTROY flag is set, the file descriptor
has already been closed and the nr_release() function has been called.
So it makes no sense to hold the reference count because no one will
call another nr_destroy_socket() and put it as in the case "b."
nr_connect
nr_establish_data_link
nr_start_heartbeat
nr_release
switch (nr->state)
case NR_STATE_3
nr->state = NR_STATE_2
sock_set_flag(sk, SOCK_DESTROY);
nr_rx_frame
nr_process_rx_frame
switch (nr->state)
case NR_STATE_2
nr_state2_machine()
nr_disconnect()
nr_sk(sk)->state = NR_STATE_0
sock_set_flag(sk, SOCK_DEAD)
nr_heartbeat_expiry
switch (nr->state)
case NR_STATE_0
if (sock_flag(sk, SOCK_DESTROY) ||
(sk->sk_state == TCP_LISTEN
&& sock_flag(sk, SOCK_DEAD)))
sock_hold() // ( !!! )
nr_destroy_socket()
To fix the memory leak, let's call sock_hold() only for a listening socket.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: validate user input for expected length
I got multiple syzbot reports showing old bugs exposed
by BPF after commit 20f2505fb436 ("bpf: Try to avoid kzalloc
in cgroup/{s,g}etsockopt")
setsockopt() @optlen argument should be taken into account
before copying data.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Prevent lock inversion deadlock in map delete elem
syzkaller started using corpuses where a BPF tracing program deletes
elements from a sockmap/sockhash map. Because BPF tracing programs can be
invoked from any interrupt context, locks taken during a map_delete_elem
operation must be hardirq-safe. Otherwise a deadlock due to lock inversion
is possible, as reported by lockdep:
CPU0 CPU1
---- ----
lock(&htab->buckets[i].lock);
local_irq_disable();
lock(&host->lock);
lock(&htab->buckets[i].lock);
<Interrupt>
lock(&host->lock);
Locks in sockmap are hardirq-unsafe by design. We expects elements to be
deleted from sockmap/sockhash only in task (normal) context with interrupts
enabled, or in softirq context.
Detect when map_delete_elem operation is invoked from a context which is
_not_ hardirq-unsafe, that is interrupts are disabled, and bail out with an

Note that map updates are not affected by this issue. BPF verifier does not
allow updating sockmap/sockhash from a BPF tracing program today.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu: Return right value in iommu_sva_bind_device()
iommu_sva_bind_device() should return either a sva bond handle or an
ERR_PTR value in error cases. Existing drivers (idxd and uacce) only
check the return value with IS_ERR(). This could potentially lead to
a kernel NULL pointer dereference issue if the function returns NULL
instead of an error pointer.
In reality, this doesn't cause any problems because iommu_sva_bind_device()
only returns NULL when the kernel is not configured with CONFIG_IOMMU_SVA.
In this case, iommu_dev_enable_feature(dev, IOMMU_DEV_FEAT_SVA) will
return an error, and the device drivers won't call iommu_sva_bind_device()
at all.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mac802154: fix llsec key resources release in mac802154_llsec_key_del
mac802154_llsec_key_del() can free resources of a key directly without
following the RCU rules for waiting before the end of a grace period. This
may lead to use-after-free in case llsec_lookup_key() is traversing the
list of keys in parallel with a key deletion:
refcount_t: addition on 0; use-after-free.

Handle the proper resource release in the RCU callback function
mac802154_llsec_key_del_rcu().
Note that if llsec_lookup_key() finds a key, it gets a refcount via
llsec_key_get() and locally copies key id from key_entry (which is a
list element). So it's safe to call llsec_key_put() and free the list
entry after the RCU grace period elapses.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: sanity check symbolic link size
Syzkiller reports a "KMSAN: uninit-value in pick_link" bug.
This is caused by an uninitialised page, which is ultimately caused
by a corrupted symbolic link size read from disk.
The reason why the corrupted symlink size causes an uninitialised
page is due to the following sequence of events:
1. squashfs_read_inode() is called to read the symbolic
link from disk. This assigns the corrupted value
3875536935 to inode->i_size.
2. Later squashfs_symlink_read_folio() is called, which assigns
this corrupted value to the length variable, which being a
signed int, overflows producing a negative number.
3. The following loop that fills in the page contents checks that
the copied bytes is less than length, which being negative means
the loop is skipped, producing an uninitialised page.
This patch adds a sanity check which checks that the symbolic
link size is not larger than expected.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: phy: dp83869: fix memory corruption when enabling fiber
When configuring the fiber port, the DP83869 PHY driver incorrectly
calls linkmode_set_bit() with a bit mask (1 << 10) rather than a bit
number (10). This corrupts some other memory location -- in case of
arm64 the priv pointer in the same structure.
Since the advertising flags are updated from supported at the end of the
function the incorrect line isn't needed at all and can be removed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
udf: Avoid using corrupted block bitmap buffer
When the filesystem block bitmap is corrupted, we detect the corruption
while loading the bitmap and fail the allocation with error. However the
next allocation from the same bitmap will notice the bitmap buffer is
already loaded and tries to allocate from the bitmap with mixed results
(depending on the exact nature of the bitmap corruption). Fix the
problem by using BH_verified bit to indicate whether the bitmap is valid
or not.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_reject_ipv6: fix nf_reject_ip6_tcphdr_put()
syzbot reported that nf_reject_ip6_tcphdr_put() was possibly sending
garbage on the four reserved tcp bits (th->res1)
Use skb_put_zero() to clear the whole TCP header,
as done in nf_reject_ip_tcphdr_put()

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: add check that partition length needs to be aligned with block size
Before calling add partition or resize partition, there is no check
on whether the length is aligned with the logical block size.
If the logical block size of the disk is larger than 512 bytes,
then the partition size maybe not the multiple of the logical block size,
and when the last sector is read, bio_truncate() will adjust the bio size,
resulting in an IO error if the size of the read command is smaller than
the logical block size.If integrity data is supported, this will also
result in a null pointer dereference when calling bio_integrity_free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: complete validation of user input
In my recent commit, I missed that do_replace() handlers
use copy_from_sockptr() (which I fixed), followed
by unsafe copy_from_sockptr_offset() calls.
In all functions, we can perform the @optlen validation
before even calling xt_alloc_table_info() with the following
check:
if ((u64)optlen < (u64)tmp.size + sizeof(tmp))
return -EINVAL;

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: check skb is non-NULL in tcp_rto_delta_us()
We have some machines running stock Ubuntu 20.04.6 which is their 5.4.0-174-generic
kernel that are running ceph and recently hit a null ptr dereference in
tcp_rearm_rto(). Initially hitting it from the TLP path, but then later we also
saw it getting hit from the RACK case as well. Here are examples of the oops
messages we saw in each of those cases:

Summary
Issue summary: Calling the OpenSSL API function SSL_select_next_proto with an
empty supported client protocols buffer may cause a crash or memory contents to
be sent to the peer.
Impact summary: A buffer overread can have a range of potential consequences
such as unexpected application beahviour or a crash. In particular this issue
could result in up to 255 bytes of arbitrary private data from memory being sent
to the peer leading to a loss of confidentiality. However, only applications
that directly call the SSL_select_next_proto function with a 0 length list of
supported client protocols are affected by this issue. This would normally never
be a valid scenario and is typically not under attacker control but may occur by
accident in the case of a configuration or programming error in the calling
application.
The OpenSSL API function SSL_select_next_proto is typically used by TLS
applications that support ALPN (Application Layer Protocol Negotiation) or NPN
(Next Protocol Negotiation). NPN is older, was never standardised and
is deprecated in favour of ALPN. We believe that ALPN is significantly more
widely deployed than NPN. The SSL_select_next_proto function accepts a list of
protocols from the server and a list of protocols from the client and returns
the first protocol that appears in the server list that also appears in the
client list. In the case of no overlap between the two lists it returns the
first item in the client list. In either case it will signal whether an overlap
between the two lists was found. In the case where SSL_select_next_proto is
called with a zero length client list it fails to notice this condition and
returns the memory immediately following the client list pointer (and reports
that there was no overlap in the lists).
This function is typically called from a server side application callback for
ALPN or a client side application callback for NPN. In the case of ALPN the list
of protocols supplied by the client is guaranteed by libssl to never be zero in
length. The list of server protocols comes from the application and should never
normally be expected to be of zero length. In this case if the
SSL_select_next_proto function has been called as expected (with the list
supplied by the client passed in the client/client_len parameters), then the
application will not be vulnerable to this issue. If the application has
accidentally been configured with a zero length server list, and has
accidentally passed that zero length server list in the client/client_len
parameters, and has additionally failed to correctly handle a "no overlap"
response (which would normally result in a handshake failure in ALPN) then it
will be vulnerable to this problem.
In the case of NPN, the protocol permits the client to opportunistically select
a protocol when there is no overlap. OpenSSL returns the first client protocol
in the no overlap case in support of this. The list of client protocols comes
from the application and should never normally be expected to be of zero length.
However if the SSL_select_next_proto function is accidentally called with a
client_len of 0 then an invalid memory pointer will be returned instead. If the
application uses this output as the opportunistic protocol then the loss of
confidentiality will occur.
This issue has been assessed as Low severity because applications are most
likely to be vulnerable if they are using NPN instead of ALPN - but NPN is not
widely used. It also requires an application configuration or programming error.
Finally, this issue would not typically be under attacker control making active
exploitation unlikely.
The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.
Due to the low severity of this issue we are not issuing new releases of
OpenSSL at this time. The fix will be included in the next releases when they
become available.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix error path in multi-packet WQE transmit
Remove the erroneous unmap in case no DMA mapping was established
The multi-packet WQE transmit code attempts to obtain a DMA mapping for
the skb. This could fail, e.g. under memory pressure, when the IOMMU
driver just can't allocate more memory for page tables. While the code
tries to handle this in the path below the err_unmap label it erroneously
unmaps one entry from the sq's FIFO list of active mappings. Since the
current map attempt failed this unmap is removing some random DMA mapping
that might still be required. If the PCI function now presents that IOVA,
the IOMMU may assumes a rogue DMA access and e.g. on s390 puts the PCI
function in error state.
The erroneous behavior was seen in a stress-test environment that created
memory pressure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix i_data_sem unlock order in ext4_ind_migrate()
Fuzzing reports a possible deadlock in jbd2_log_wait_commit.
This issue is triggered when an EXT4_IOC_MIGRATE ioctl is set to require
synchronous updates because the file descriptor is opened with O_SYNC.
This can lead to the jbd2_journal_stop() function calling
jbd2_might_wait_for_commit(), potentially causing a deadlock if the
EXT4_IOC_MIGRATE call races with a write(2) system call.
This problem only arises when CONFIG_PROVE_LOCKING is enabled. In this
case, the jbd2_might_wait_for_commit macro locks jbd2_handle in the
jbd2_journal_stop function while i_data_sem is locked. This triggers
lockdep because the jbd2_journal_start function might also lock the same
jbd2_handle simultaneously.
Found by Linux Verification Center (linuxtesting.org) with syzkaller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-iocost: avoid out of bounds shift
UBSAN catches undefined behavior in blk-iocost, where sometimes
iocg->delay is shifted right by a number that is too large,
resulting in undefined behavior on some architectures.
[ 186.556576] ------------[ cut here ]------------
UBSAN: shift-out-of-bounds in block/blk-iocost.c:1366:23
shift exponent 64 is too large for 64-bit type 'u64' (aka 'unsigned long long')
CPU: 16 PID: 0 Comm: swapper/16 Tainted: G S E N 6.9.0-0_fbk700_debug_rc2_kbuilder_0_gc85af715cac0 #1
Hardware name: Quanta Twin Lakes MP/Twin Lakes Passive MP, BIOS F09_3A23 12/08/2020
Call Trace:
<IRQ>
dump_stack_lvl+0x8f/0xe0
__ubsan_handle_shift_out_of_bounds+0x22c/0x280
iocg_kick_delay+0x30b/0x310
ioc_timer_fn+0x2fb/0x1f80
__run_timer_base+0x1b6/0x250
...
Avoid that undefined behavior by simply taking the
"delay = 0" branch if the shift is too large.
I am not sure what the symptoms of an undefined value
delay will be, but I suspect it could be more than a
little annoying to debug.

Summary
In the Linux kernel, the following vulnerability has been resolved:
protect the fetch of ->fd[fd] in do_dup2() from mispredictions
both callers have verified that fd is not greater than ->max_fds;
however, misprediction might end up with
tofree = fdt->fd[fd];
being speculatively executed. That's wrong for the same reasons
why it's wrong in close_fd()/file_close_fd_locked(); the same
solution applies - array_index_nospec(fd, fdt->max_fds) could differ
from fd only in case of speculative execution on mispredicted path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock: prevent null-ptr-deref in vsock_*[has_data|has_space]
Recent reports have shown how we sometimes call vsock_*_has_data()
when a vsock socket has been de-assigned from a transport (see attached
links), but we shouldn't.
Previous commits should have solved the real problems, but we may have
more in the future, so to avoid null-ptr-deref, we can return 0
(no space, no data available) but with a warning.
This way the code should continue to run in a nearly consistent state
and have a warning that allows us to debug future problems.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix DEVMAP_HASH overflow check on 32-bit arches
The devmap code allocates a number hash buckets equal to the next power
of two of the max_entries value provided when creating the map. When
rounding up to the next power of two, the 32-bit variable storing the
number of buckets can overflow, and the code checks for overflow by
checking if the truncated 32-bit value is equal to 0. However, on 32-bit
arches the rounding up itself can overflow mid-way through, because it
ends up doing a left-shift of 32 bits on an unsigned long value. If the
size of an unsigned long is four bytes, this is undefined behaviour, so
there is no guarantee that we'll end up with a nice and tidy 0-value at
the end.
Syzbot managed to turn this into a crash on arm32 by creating a
DEVMAP_HASH with max_entries > 0x80000000 and then trying to update it.
Fix this by moving the overflow check to before the rounding up
operation.

When\nrounding up to the next power of two, the 32-bit variable storing the\nnumber of buckets can overflow, and the code checks for overflow by\nchecking if the truncated 32-bit value is equal to 0. However, on 32-bit\narches the rounding up itself can overflow mid-way through, because it\nends up doing a left-shift of 32 bits on an unsigned long value. If the\nsize of an unsigned long is four bytes, this is undefined behaviour, so\nthere is no guarantee that we\u0027ll end up with a nice and tidy 0-value at\nthe end.\n\nSyzbot managed to turn this into a crash on arm32 by creating a\nDEVMAP_HASH with max_entries \u003e 0x80000000 and then trying to update it.\nFix this by moving the overflow check to before the rounding up\noperation."

Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: Fix clk_core_get NULL dereference
It is possible for clk_core_get to dereference a NULL in the following
sequence:
clk_core_get()
of_clk_get_hw_from_clkspec()
__of_clk_get_hw_from_provider()
__clk_get_hw()
__clk_get_hw() can return NULL which is dereferenced by clk_core_get() at
hw->core.
Prior to commit dde4eff47c82 ("clk: Look for parents with clkdev based
clk_lookups") the check IS_ERR_OR_NULL() was performed which would have
caught the NULL.
Reading the description of this function it talks about returning NULL but
that cannot be so at the moment.
Update the function to check for hw before dereferencing it and return NULL
if hw is NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: restrict NL80211_ATTR_TXQ_QUANTUM values
syzbot is able to trigger softlockups, setting NL80211_ATTR_TXQ_QUANTUM
to 2^31.
We had a similar issue in sch_fq, fixed with commit
d9e15a273306 ("pkt_sched: fq: do not accept silly TCA_FQ_QUANTUM")
watchdog: BUG: soft lockup - CPU#1 stuck for 26s! [kworker/1:0:24]

Summary
In the Linux kernel, the following vulnerability has been resolved:
sysctl: always initialize i_uid/i_gid
Always initialize i_uid/i_gid inside the sysfs core so set_ownership()
can safely skip setting them.
Commit 5ec27ec735ba ("fs/proc/proc_sysctl.c: fix the default values of
i_uid/i_gid on /proc/sys inodes.") added defaults for i_uid/i_gid when
set_ownership() was not implemented. It also missed adjusting
net_ctl_set_ownership() to use the same default values in case the
computation of a better value failed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: Fix null pointer dereference in svc_rqst_free()
When alloc_pages_node() returns null in svc_rqst_alloc(), the
null rq_scratch_page pointer will be dereferenced when calling
put_page() in svc_rqst_free(). Fix it by adding a null check.
Addresses-Coverity: ("Dereference after null check")

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86, relocs: Ignore relocations in .notes section
When building with CONFIG_XEN_PV=y, .text symbols are emitted into
the .notes section so that Xen can find the "startup_xen" entry point.
This information is used prior to booting the kernel, so relocations
are not useful. In fact, performing relocations against the .notes
section means that the KASLR base is exposed since /sys/kernel/notes
is world-readable.
To avoid leaking the KASLR base without breaking unprivileged tools that
are expecting to read /sys/kernel/notes, skip performing relocations in
the .notes section. The values readable in .notes are then identical to
those found in System.map.

Summary
Issue summary: Generating excessively long X9.42 DH keys or checking
excessively long X9.42 DH keys or parameters may be very slow.
Impact summary: Applications that use the functions DH_generate_key() to
generate an X9.42 DH key may experience long delays. Likewise, applications
that use DH_check_pub_key(), DH_check_pub_key_ex() or EVP_PKEY_public_check()
to check an X9.42 DH key or X9.42 DH parameters may experience long delays.
Where the key or parameters that are being checked have been obtained from
an untrusted source this may lead to a Denial of Service.
While DH_check() performs all the necessary checks (as of CVE-2023-3817),
DH_check_pub_key() doesn't make any of these checks, and is therefore
vulnerable for excessively large P and Q parameters.
Likewise, while DH_generate_key() performs a check for an excessively large
P, it doesn't check for an excessively large Q.
An application that calls DH_generate_key() or DH_check_pub_key() and
supplies a key or parameters obtained from an untrusted source could be
vulnerable to a Denial of Service attack.
DH_generate_key() and DH_check_pub_key() are also called by a number of
other OpenSSL functions. An application calling any of those other
functions may similarly be affected. The other functions affected by this
are DH_check_pub_key_ex(), EVP_PKEY_public_check(), and EVP_PKEY_generate().
Also vulnerable are the OpenSSL pkey command line application when using the
"-pubcheck" option, as well as the OpenSSL genpkey command line application.
The OpenSSL SSL/TLS implementation is not affected by this issue.
The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers: media: dvb-frontends/rtl2830: fix an out-of-bounds write error
Ensure index in rtl2830_pid_filter does not exceed 31 to prevent
out-of-bounds access.
dev->filters is a 32-bit value, so set_bit and clear_bit functions should
only operate on indices from 0 to 31. If index is 32, it will attempt to
access a non-existent 33rd bit, leading to out-of-bounds access.
Change the boundary check from index > 32 to index >= 32 to resolve this
issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: act_api: fix possible infinite loop in tcf_idr_check_alloc()
syzbot found hanging tasks waiting on rtnl_lock [1]
A reproducer is available in the syzbot bug.
When a request to add multiple actions with the same index is sent, the
second request will block forever on the first request. This holds
rtnl_lock, and causes tasks to hang.
Return -EAGAIN to prevent infinite looping, while keeping documented
behavior.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: use timestamp to check for set element timeout
Add a timestamp field at the beginning of the transaction, store it
in the nftables per-netns area.
Update set backend .insert, .deactivate and sync gc path to use the
timestamp, this avoids that an element expires while control plane
transaction is still unfinished.
.lookup and .update, which are used from packet path, still use the
current time to check if the element has expired. And .get path and dump
also since this runs lockless under rcu read size lock. Then, there is
async gc which also needs to check the current time since it runs
asynchronously from a workqueue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: Fix potential data-race in __nft_expr_type_get()
nft_unregister_expr() can concurrent with __nft_expr_type_get(),
and there is not any protection when iterate over nf_tables_expressions
list in __nft_expr_type_get(). Therefore, there is potential data-race
of nf_tables_expressions list entry.
Use list_for_each_entry_rcu() to iterate over nf_tables_expressions
list in __nft_expr_type_get(), and use rcu_read_lock() in the caller
nft_expr_type_get() to protect the entire type query process.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Fix READDIR buffer overflow
If a client sends a READDIR count argument that is too small (say,
zero), then the buffer size calculation in the new init_dirlist
helper functions results in an underflow, allowing the XDR stream
functions to write beyond the actual buffer.
This calculation has always been suspect. NFSD has never sanity-
checked the READDIR count argument, but the old entry encoders
managed the problem correctly.
With the commits below, entry encoding changed, exposing the
underflow to the pointer arithmetic in xdr_reserve_space().
Modern NFS clients attempt to retrieve as much data as possible
for each READDIR request. Also, we have no unit tests that
exercise the behavior of READDIR at the lower bound of @count
values. Thus this case was missed during testing.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: fix missing memory barrier in tls_init
In tls_init(), a write memory barrier is missing, and store-store
reordering may cause NULL dereference in tls_{setsockopt,getsockopt}.
CPU0 CPU1
----- -----
// In tls_init()
// In tls_ctx_create()
ctx = kzalloc()
ctx->sk_proto = READ_ONCE(sk->sk_prot) -(1)
// In update_sk_prot()
WRITE_ONCE(sk->sk_prot, tls_prots) -(2)
// In sock_common_setsockopt()
READ_ONCE(sk->sk_prot)->setsockopt()
// In tls_{setsockopt,getsockopt}()
ctx->sk_proto->setsockopt() -(3)
In the above scenario, when (1) and (2) are reordered, (3) can observe
the NULL value of ctx->sk_proto, causing NULL dereference.
To fix it, we rely on rcu_assign_pointer() which implies the release
barrier semantic. By moving rcu_assign_pointer() after ctx->sk_proto is
initialized, we can ensure that ctx->sk_proto are visible when
changing sk->sk_prot.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: conntrack: clamp maximum hashtable size to INT_MAX
Use INT_MAX as maximum size for the conntrack hashtable. Otherwise, it
is possible to hit WARN_ON_ONCE in __kvmalloc_node_noprof() when
resizing hashtable because __GFP_NOWARN is unset. See:
0708a0afe291 ("mm: Consider __GFP_NOWARN flag for oversized kvmalloc() calls")
Note: hashtable resize is only possible from init_netns.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: use two-phase skb reclamation in ieee80211_do_stop()
Since '__dev_queue_xmit()' should be called with interrupts enabled,
the following backtrace:
ieee80211_do_stop()
...
spin_lock_irqsave(&local->queue_stop_reason_lock, flags)
...

__dev_queue_xmit() ; with IRQS disabled
...
spin_unlock_irqrestore(&local->queue_stop_reason_lock, flags)
issues the warning (as reported by syzbot reproducer):
WARNING: CPU: 2 PID: 5128 at kernel/softirq.c:362 __local_bh_enable_ip+0xc3/0x120
Fix this by implementing a two-phase skb reclamation in
'ieee80211_do_stop()', where actual work is performed
outside of a section with interrupts disabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix potential index out of bounds in color transformation function
Fixes index out of bounds issue in the color transformation function.
The issue could occur when the index 'i' exceeds the number of transfer
function points (TRANSFER_FUNC_POINTS).
The fix adds a check to ensure 'i' is within bounds before accessing the
transfer function points. If 'i' is out of bounds, an error message is
logged and the function returns false to indicate an error.
Reported by smatch:

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/client: Fully protect modes[] with dev->mode_config.mutex
The modes[] array contains pointers to modes on the connectors'
mode lists, which are protected by dev->mode_config.mutex.
Thus we need to extend modes[] the same protection or by the
time we use it the elements may already be pointing to
freed/reused memory.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ip_tunnel: make sure to pull inner header in ip_tunnel_rcv()
Apply the same fix than ones found in :
8d975c15c0cd ("ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()")
1ca1ba465e55 ("geneve: make sure to pull inner header in geneve_rx()")
We have to save skb->network_header in a temporary variable
in order to be able to recompute the network_header pointer
after a pskb_inet_may_pull() call.
pskb_inet_may_pull() makes sure the needed headers are in skb->head.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jfs: fix out-of-bounds in dbNextAG() and diAlloc()
In dbNextAG() , there is no check for the case where bmp->db_numag is
greater or same than MAXAG due to a polluted image, which causes an
out-of-bounds. Therefore, a bounds check should be added in dbMount().
And in dbNextAG(), a check for the case where agpref is greater than
bmp->db_numag should be added, so an out-of-bounds exception should be
prevented.
Additionally, a check for the case where agno is greater or same than
MAXAG should be added in diAlloc() to prevent out-of-bounds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: smbus: fix NULL function pointer dereference
Baruch reported an OOPS when using the designware controller as target
only. Target-only modes break the assumption of one transfer function
always being available. Fix this by always checking the pointer in
__i2c_transfer.
[wsa: dropped the simplification in core-smbus to avoid theoretical regressions]

Summary
In the Linux kernel, the following vulnerability has been resolved:
bcache: fix variable length array abuse in btree_iter
btree_iter is used in two ways: either allocated on the stack with a
fixed size MAX_BSETS, or from a mempool with a dynamic size based on the
specific cache set. Previously, the struct had a fixed-length array of
size MAX_BSETS which was indexed out-of-bounds for the dynamically-sized
iterators, which causes UBSAN to complain.
This patch uses the same approach as in bcachefs's sort_iter and splits
the iterator into a btree_iter with a flexible array member and a
btree_iter_stack which embeds a btree_iter as well as a fixed-length
data array.

Previously, the struct had a fixed-length array of\nsize MAX_BSETS which was indexed out-of-bounds for the dynamically-sized\niterators, which causes UBSAN to complain.\n\nThis patch uses the same approach as in bcachefs\u0027s sort_iter and splits\nthe iterator into a btree_iter with a flexible array member and a\nbtree_iter_stack which embeds a btree_iter as well as a fixed-length\ndata array."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/ipv6: avoid possible UAF in ip6_route_mpath_notify()
syzbot found another use-after-free in ip6_route_mpath_notify() [1]
Commit f7225172f25a ("net/ipv6: prevent use after free in
ip6_route_mpath_notify") was not able to fix the root cause.
We need to defer the fib6_info_release() calls after
ip6_route_mpath_notify(), in the cleanup phase.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: fix vf may be used uninitialized in this function warning
To fix the regression introduced by commit 52424f974bc5, which causes
servers hang in very hard to reproduce conditions with resets races.
Using two sources for the information is the root cause.
In this function before the fix bumping v didn't mean bumping vf
pointer. But the code used this variables interchangeably, so stale vf
could point to different/not intended vf.
Remove redundant "v" variable and iterate via single VF pointer across
whole function instead to guarantee VF pointer validity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: rfcomm: Fix null-ptr-deref in rfcomm_check_security
During our fuzz testing of the connection and disconnection process at the
RFCOMM layer, we discovered this bug. By comparing the packets from a
normal connection and disconnection process with the testcase that
triggered a KASAN report. We analyzed the cause of this bug as follows:
1. In the packets captured during a normal connection, the host sends a
`Read Encryption Key Size` type of `HCI_CMD` packet
(Command Opcode: 0x1408) to the controller to inquire the length of
encryption key.After receiving this packet, the controller immediately
replies with a Command Completepacket (Event Code: 0x0e) to return the
Encryption Key Size.
2. In our fuzz test case, the timing of the controller's response to this
packet was delayed to an unexpected point: after the RFCOMM and L2CAP
layers had disconnected but before the HCI layer had disconnected.
3. After receiving the Encryption Key Size Response at the time described
in point 2, the host still called the rfcomm_check_security function.
However, by this time `struct l2cap_conn *conn = l2cap_pi(sk)->chan->conn;`
had already been released, and when the function executed
`return hci_conn_security(conn->hcon, d->sec_level, auth_type, d->out);`,
specifically when accessing `conn->hcon`, a null-ptr-deref error occurred.
To fix this bug, check if `sk->sk_state` is BT_CLOSED before calling
rfcomm_recv_frame in rfcomm_process_rx.

In the packets captured during a normal connection, the host sends a\n`Read Encryption Key Size` type of `HCI_CMD` packet\n(Command Opcode: 0x1408) to the controller to inquire the length of\nencryption key.After receiving this packet, the controller immediately\nreplies with a Command Completepacket (Event Code: 0x0e) to return the\nEncryption Key Size.\n\n2. In our fuzz test case, the timing of the controller\u0027s response to this\npacket was delayed to an unexpected point: after the RFCOMM and L2CAP\nlayers had disconnected but before the HCI layer had disconnected.\n\n3. After receiving the Encryption Key Size Response at the time described\nin point 2, the host still called the rfcomm_check_security function.\nHowever, by this time `struct l2cap_conn *conn = l2cap_pi(sk)-\u003echan-\u003econn;`\nhad already been released, and when the function executed\n`return hci_conn_security(conn-\u003ehcon, d-\u003esec_level, auth_type, d-\u003eout);`,\nspecifically when accessing `conn-\u003ehcon`, a null-ptr-deref error occurred.\n\nTo fix this bug, check if `sk-\u003esk_state` is BT_CLOSED before calling\nrfcomm_recv_frame in rfcomm_process_rx."

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix potential null-ptr-deref in nilfs_btree_insert()
Patch series "nilfs2: fix potential issues with empty b-tree nodes".
This series addresses three potential issues with empty b-tree nodes that
can occur with corrupted filesystem images, including one recently
discovered by syzbot.
This patch (of 3):
If a b-tree is broken on the device, and the b-tree height is greater than
2 (the level of the root node is greater than 1) even if the number of
child nodes of the b-tree root is 0, a NULL pointer dereference occurs in
nilfs_btree_prepare_insert(), which is called from nilfs_btree_insert().
This is because, when the number of child nodes of the b-tree root is 0,
nilfs_btree_do_lookup() does not set the block buffer head in any of
path[x].bp_bh, leaving it as the initial value of NULL, but if the level
of the b-tree root node is greater than 1, nilfs_btree_get_nonroot_node(),
which accesses the buffer memory of path[x].bp_bh, is called.
Fix this issue by adding a check to nilfs_btree_root_broken(), which
performs sanity checks when reading the root node from the device, to
detect this inconsistency.
Thanks to Lizhi Xu for trying to solve the bug and clarifying the cause
early on.

wifi: wilc1000: prevent use-after-free on vif when cleaning up all interfaces
wilc_netdev_cleanup currently triggers a KASAN warning, which can be
observed on interface registration error path, or simply by
removing the module/unbinding device from driver:
echo spi0.1 > /sys/bus/spi/drivers/wilc1000_spi/unbind

David Mosberger-Tan initial investigation [1] showed that this
use-after-free is due to netdevice unregistration during vif list
traversal. When unregistering a net device, since the needs_free_netdev has
been set to true during registration, the netdevice object is also freed,
and as a consequence, the corresponding vif object too, since it is
attached to it as private netdevice data. The next occurrence of the loop
then tries to access freed vif pointer to the list to move forward in the
list.
Fix this use-after-free thanks to two mechanisms:
- navigate in the list with list_for_each_entry_safe, which allows to
safely modify the list as we go through each element. For each element,
remove it from the list with list_del_rcu
- make sure to wait for RCU grace period end after each vif removal to make
sure it is safe to free the corresponding vif too (through
unregister_netdev)
Since we are in a RCU "modifier" path (not a "reader" path), and because
such path is expected not to be concurrent to any other modifier (we are
using the vif_mutex lock), we do not need to use RCU list API, that's why
we can benefit from list_for_each_entry_safe.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: Add missing bridge lock to pci_bus_lock()
One of the true positives that the cfg_access_lock lockdep effort
identified is this sequence:
WARNING: CPU: 14 PID: 1 at drivers/pci/pci.c:4886 pci_bridge_secondary_bus_reset+0x5d/0x70
RIP: 0010:pci_bridge_secondary_bus_reset+0x5d/0x70
Call Trace:
<TASK>
? __warn+0x8c/0x190
? pci_bridge_secondary_bus_reset+0x5d/0x70
? report_bug+0x1f8/0x200
? handle_bug+0x3c/0x70

pci_reset_bus+0x1d8/0x270
vmd_probe+0x778/0xa10
pci_device_probe+0x95/0x120
Where pci_reset_bus() users are triggering unlocked secondary bus resets.
Ironically pci_bus_reset(), several calls down from pci_reset_bus(), uses
pci_bus_lock() before issuing the reset which locks everything *but* the
bridge itself.
For the same motivation as adding:
bridge = pci_upstream_bridge(dev);
if (bridge)
pci_dev_lock(bridge);
to pci_reset_function() for the "bus" and "cxl_bus" reset cases, add
pci_dev_lock() for @bus->self to pci_bus_lock().

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: bcm - Fix pointer arithmetic
In spu2_dump_omd() value of ptr is increased by ciph_key_len
instead of hash_iv_len which could lead to going beyond the
buffer boundaries.
Fix this bug by changing ciph_key_len to hash_iv_len.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Historically, the signed integer overflow sanitizer did not work in the
kernel due to its interaction with `-fwrapv` but this has since been
changed [1] in the newest version of Clang; It was re-enabled in the
kernel with Commit 557f8c582a9ba8ab ("ubsan: Reintroduce signed overflow
sanitizer").
Let's rework this overflow checking logic to not actually perform an
overflow during the check itself, thus avoiding the UBSAN splat.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bonding: fix xfrm real_dev null pointer dereference
We shouldn't set real_dev to NULL because packets can be in transit and
xfrm might call xdo_dev_offload_ok() in parallel. All callbacks assume
real_dev is set.
Example trace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: protect uart_port_dtr_rts() in uart_shutdown() too
Commit af224ca2df29 (serial: core: Prevent unsafe uart port access, part
3) added few uport == NULL checks. It added one to uart_shutdown(), so
the commit assumes, uport can be NULL in there. But right after that
protection, there is an unprotected "uart_port_dtr_rts(uport, false);"
call. That is invoked only if HUPCL is set, so I assume that is the
reason why we do not see lots of these reports.
Or it cannot be NULL at this point at all for some reason :P.
Until the above is investigated, stay on the safe side and move this
dereference to the if too.
I got this inconsistency from Coverity under CID 1585130. Thanks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: add missing condition check for existence of mapped data
nvme_map_data() is called when request has physical segments, hence
the nvme_unmap_data() should have same condition to avoid dereference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: core: Fix null-ptr-deref in target_alloc_device()
There is a null-ptr-deref issue reported by KASAN:
BUG: KASAN: null-ptr-deref in target_alloc_device+0xbc4/0xbe0 [target_core_mod]
...
kasan_report+0xb9/0xf0
target_alloc_device+0xbc4/0xbe0 [target_core_mod]
core_dev_setup_virtual_lun0+0xef/0x1f0 [target_core_mod]
target_core_init_configfs+0x205/0x420 [target_core_mod]
do_one_initcall+0xdd/0x4e0
...
entry_SYSCALL_64_after_hwframe+0x76/0x7e
In target_alloc_device(), if allocing memory for dev queues fails, then
dev will be freed by dev->transport->free_device(), but dev->transport
is not initialized at that time, which will lead to a null pointer
reference problem.
Fixing this bug by freeing dev with hba->backend->ops->free_device().

Bytes 40-65535 of 65536 are uninitialized
Memory access of size 65536 starts at ffff888045a40000
This happens, because we're copying a 'struct btrfs_data_container' back
to user-space. This btrfs_data_container is allocated in
'init_data_container()' via kvmalloc(), which does not zero-fill the
memory.
Fix this by using kvzalloc() which zeroes out the memory on allocation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Build event generation tests only as modules
The kprobes and synth event generation test modules add events and lock
(get a reference) those event file reference in module init function,
and unlock and delete it in module exit function. This is because those
are designed for playing as modules.
If we make those modules as built-in, those events are left locked in the
kernel, and never be removed. This causes kprobe event self-test failure
as below.

And also, since we can not cleanup dynamic_event file, ftracetest are
failed too.
To avoid these issues, build these tests only as modules.

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: core: Fix deadlock in usb_deauthorize_interface()
Among the attribute file callback routines in
drivers/usb/core/sysfs.c, the interface_authorized_store() function is
the only one which acquires a device lock on an ancestor device: It
calls usb_deauthorize_interface(), which locks the interface's parent
USB device.
The will lead to deadlock if another process already owns that lock
and tries to remove the interface, whether through a configuration
change or because the device has been disconnected. As part of the
removal procedure, device_del() waits for all ongoing sysfs attribute
callbacks to complete. But usb_deauthorize_interface() can't complete
until the device lock has been released, and the lock won't be
released until the removal has finished.
The mechanism provided by sysfs to prevent this kind of deadlock is
to use the sysfs_break_active_protection() function, which tells sysfs
not to wait for the attribute callback.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86: stop playing stack games in profile_pc()
The 'profile_pc()' function is used for timer-based profiling, which
isn't really all that relevant any more to begin with, but it also ends
up making assumptions based on the stack layout that aren't necessarily
valid.
Basically, the code tries to account the time spent in spinlocks to the
caller rather than the spinlock, and while I support that as a concept,
it's not worth the code complexity or the KASAN warnings when no serious
profiling is done using timers anyway these days.
And the code really does depend on stack layout that is only true in the
simplest of cases. We've lost the comment at some point (I think when
the 32-bit and 64-bit code was unified), but it used to say:
Assume the lock function has either no stack frame or a copy
of eflags from PUSHF.
which explains why it just blindly loads a word or two straight off the
stack pointer and then takes a minimal look at the values to just check
if they might be eflags or the return pc:
Eflags always has bits 22 and up cleared unlike kernel addresses
but that basic stack layout assumption assumes that there isn't any lock
debugging etc going on that would complicate the code and cause a stack
frame.
It causes KASAN unhappiness reported for years by syzkaller [1] and
others [2].
With no real practical reason for this any more, just remove the code.
Just for historical interest, here's some background commits relating to
this code from 2006:
0cb91a229364 ("i386: Account spinlocks to the caller during profiling for !FP kernels")
31679f38d886 ("Simplify profile_pc on x86-64")
and a code unification from 2009:
ef4512882dbe ("x86: time_32/64.c unify profile_pc")
but the basics of this thing actually goes back to before the git tree.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: sysctl: rto_min/max: avoid using current->nsproxy
As mentioned in a previous commit of this series, using the 'net'
structure via 'current' is not recommended for different reasons:
- Inconsistency: getting info from the reader's/writer's netns vs only
from the opener's netns.
- current->nsproxy can be NULL in some cases, resulting in an 'Oops'
(null-ptr-deref), e.g. when the current task is exiting, as spotted by
syzbot [1] using acct(2).
The 'net' structure can be obtained from the table->data using
container_of().
Note that table->data could also be used directly, as this is the only
member needed from the 'net' structure, but that would increase the size
of this fix, to use '*data' everywhere 'net->sctp.rto_min/max' is used.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmit
Syzbot points out that skb_trim() has a sanity check on the existing length of
the skb, which can be uninitialised in some error paths. The intent here is
clearly just to reset the length to zero before resubmitting, so switch to
calling __skb_set_length(skb, 0) directly. In addition, __skb_set_length()
already contains a call to skb_reset_tail_pointer(), so remove the redundant
call.
The syzbot report came from ath9k_hif_usb_reg_in_cb(), but there's a similar
usage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we're at it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: Fix zero-division error when disabling tc cbs
The commit b8c43360f6e4 ("net: stmmac: No need to calculate speed divider
when offload is disabled") allows the "port_transmit_rate_kbps" to be
set to a value of 0, which is then passed to the "div_s64" function when
tc-cbs is disabled. This leads to a zero-division error.
When tc-cbs is disabled, the idleslope, sendslope, and credit values the
credit values are not required to be configured. Therefore, adding a return
statement after setting the txQ mode to DCB when tc-cbs is disabled would
prevent a zero-division error.

tun->dev = dev
//ip link set tun0 netns ns1
put_net() //ref is 0
__tun_chr_ioctl() //TUNGETDEVNETNS

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: core: zero-initialize the report buffer
Since the report buffer is used by all kinds of drivers in various ways, let's
zero-initialize it during allocation to make sure that it can't be ever used
to leak kernel memory via specially-crafted report.

purpose of this commit was to stop memory mappings for operation
regions from overlapping page boundaries, as it can trigger warnings
if different page attributes are present.
However, it was found that when this situation arises, mapping
continues until the boundary's end, but there is still an attempt to
read/write the entire length of the map, leading to a NULL pointer
deference. For example, if a four-byte mapping request is made but
only one byte is mapped because it hits the current page boundary's
end, a four-byte read/write attempt is still made, resulting in a NULL
pointer deference.
Instead, map the entire length, as the ACPI specification does not
mandate that it must be within the same page boundary. It is
permissible for it to be mapped across different regions.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: swap: fix race between free_swap_and_cache() and swapoff()
There was previously a theoretical window where swapoff() could run and
teardown a swap_info_struct while a call to free_swap_and_cache() was
running in another thread. This could cause, amongst other bad
possibilities, swap_page_trans_huge_swapped() (called by
free_swap_and_cache()) to access the freed memory for swap_map.
This is a theoretical problem and I haven't been able to provoke it from a
test case. But there has been agreement based on code review that this is
possible (see link below).
Fix it by using get_swap_device()/put_swap_device(), which will stall
swapoff(). There was an extra check in _swap_info_get() to confirm that
the swap entry was not free. This isn't present in get_swap_device()
because it doesn't make sense in general due to the race between getting
the reference and swapoff. So I've added an equivalent check directly in
free_swap_and_cache().
Details of how to provoke one possible issue (thanks to David Hildenbrand
for deriving this):
--8<-----
__swap_entry_free() might be the last user and result in
"count == SWAP_HAS_CACHE".
swapoff->try_to_unuse() will stop as soon as soon as si->inuse_pages==0.
So the question is: could someone reclaim the folio and turn
si->inuse_pages==0, before we completed swap_page_trans_huge_swapped().
Imagine the following: 2 MiB folio in the swapcache. Only 2 subpages are
still references by swap entries.
Process 1 still references subpage 0 via swap entry.
Process 2 still references subpage 1 via swap entry.
Process 1 quits. Calls free_swap_and_cache().
-> count == SWAP_HAS_CACHE
[then, preempted in the hypervisor etc.]
Process 2 quits. Calls free_swap_and_cache().
-> count == SWAP_HAS_CACHE
Process 2 goes ahead, passes swap_page_trans_huge_swapped(), and calls
__try_to_reclaim_swap().
__try_to_reclaim_swap()->folio_free_swap()->delete_from_swap_cache()->
put_swap_folio()->free_swap_slot()->swapcache_free_entries()->
swap_entry_free()->swap_range_free()->
...
WRITE_ONCE(si->inuse_pages, si->inuse_pages - nr_entries);
What stops swapoff to succeed after process 2 reclaimed the swap cache
but before process1 finished its call to swap_page_trans_huge_swapped()?

This could cause, amongst other bad\npossibilities, swap_page_trans_huge_swapped() (called by\nfree_swap_and_cache()) to access the freed memory for swap_map.\n\nThis is a theoretical problem and I haven\u0027t been able to provoke it from a\ntest case. But there has been agreement based on code review that this is\npossible (see link below).\n\nFix it by using get_swap_device()/put_swap_device(), which will stall\nswapoff(). There was an extra check in _swap_info_get() to confirm that\nthe swap entry was not free. This isn\u0027t present in get_swap_device()\nbecause it doesn\u0027t make sense in general due to the race between getting\nthe reference and swapoff. So I\u0027ve added an equivalent check directly in\nfree_swap_and_cache().\n\nDetails of how to provoke one possible issue (thanks to David Hildenbrand\nfor deriving this):\n\n--8\u003c-----\n\n__swap_entry_free() might be the last user and result in\n\"count == SWAP_HAS_CACHE\".\n\nswapoff-\u003etry_to_unuse() will stop as soon as soon as si-\u003einuse_pages==0.\n\nSo the question is: could someone reclaim the folio and turn\nsi-\u003einuse_pages==0, before we completed swap_page_trans_huge_swapped().\n\nImagine the following: 2 MiB folio in the swapcache. Only 2 subpages are\nstill references by swap entries.\n\nProcess 1 still references subpage 0 via swap entry.\nProcess 2 still references subpage 1 via swap entry.\n\nProcess 1 quits. Calls free_swap_and_cache().\n-\u003e count == SWAP_HAS_CACHE\n[then, preempted in the hypervisor etc.]\n\nProcess 2 quits. Calls free_swap_and_cache().\n-\u003e count == SWAP_HAS_CACHE\n\nProcess 2 goes ahead, passes swap_page_trans_huge_swapped(), and calls\n__try_to_reclaim_swap().\n\n__try_to_reclaim_swap()-\u003efolio_free_swap()-\u003edelete_from_swap_cache()-\u003e\nput_swap_folio()-\u003efree_swap_slot()-\u003eswapcache_free_entries()-\u003e\nswap_entry_free()-\u003eswap_range_free()-\u003e\n...\nWRITE_ONCE(si-\u003einuse_pages, si-\u003einuse_pages - nr_entries);\n\nWhat stops swapoff to succeed after process 2 reclaimed the swap cache\nbut before process1 finished its call to swap_page_trans_huge_swapped()?\n\n--8\u003c-----"

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: taprio: always validate TCA_TAPRIO_ATTR_PRIOMAP
If one TCA_TAPRIO_ATTR_PRIOMAP attribute has been provided,
taprio_parse_mqprio_opt() must validate it, or userspace
can inject arbitrary data to the kernel, the second time
taprio_change() is called.
First call (with valid attributes) sets dev->num_tc
to a non zero value.
Second call (with arbitrary mqprio attributes)
returns early from taprio_parse_mqprio_opt()
and bad things can happen.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-tpg: fix some memleaks in tpg_alloc
In tpg_alloc, resources should be deallocated in each and every
error-handling paths, since they are allocated in for statements.
Otherwise there would be memleaks because tpg_free is called only when
tpg_alloc return 0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI/DPC: Fix use-after-free on concurrent DPC and hot-removal
Keith reports a use-after-free when a DPC event occurs concurrently to
hot-removal of the same portion of the hierarchy:
The dpc_handler() awaits readiness of the secondary bus below the
Downstream Port where the DPC event occurred. To do so, it polls the
config space of the first child device on the secondary bus. If that
child device is concurrently removed, accesses to its struct pci_dev
cause the kernel to oops.
That's because pci_bridge_wait_for_secondary_bus() neglects to hold a
reference on the child device. Before v6.3, the function was only
called on resume from system sleep or on runtime resume. Holding a
reference wasn't necessary back then because the pciehp IRQ thread
could never run concurrently. (On resume from system sleep, IRQs are
not enabled until after the resume_noirq phase. And runtime resume is
always awaited before a PCI device is removed.)
However starting with v6.3, pci_bridge_wait_for_secondary_bus() is also
called on a DPC event. Commit 53b54ad074de ("PCI/DPC: Await readiness
of secondary bus after reset"), which introduced that, failed to
appreciate that pci_bridge_wait_for_secondary_bus() now needs to hold a
reference on the child device because dpc_handler() and pciehp may
indeed run concurrently. The commit was backported to v5.10+ stable
kernels, so that's the oldest one affected.
Add the missing reference acquisition.
Abridged stack trace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: stop qdisc_tree_reduce_backlog on TC_H_ROOT
In qdisc_tree_reduce_backlog, Qdiscs with major handle ffff: are assumed
to be either root or ingress. This assumption is bogus since it's valid
to create egress qdiscs with major handle ffff:
Budimir Markovic found that for qdiscs like DRR that maintain an active
class list, it will cause a UAF with a dangling class pointer.
In 066a3b5b2346, the concern was to avoid iterating over the ingress
qdisc since its parent is itself. The proper fix is to stop when parent
TC_H_ROOT is reached because the only way to retrieve ingress is when a
hierarchy which does not contain a ffff: major handle call into
qdisc_lookup with TC_H_MAJ(TC_H_ROOT).
In the scenario where major ffff: is an egress qdisc in any of the tree
levels, the updates will also propagate to TC_H_ROOT, which then the
iteration must stop.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Don't issue ATS Invalidation request when device is disconnected
For those endpoint devices connect to system via hotplug capable ports,
users could request a hot reset to the device by flapping device's link
through setting the slot's link control register, as pciehp_ist() DLLSC
interrupt sequence response, pciehp will unload the device driver and
then power it off. thus cause an IOMMU device-TLB invalidation (Intel
VT-d spec, or ATS Invalidation in PCIe spec r6.1) request for non-existence
target device to be sent and deadly loop to retry that request after ITE
fault triggered in interrupt context.
That would cause following continuous hard lockup warning and system hang
[ 4211.433662] pcieport 0000:17:01.0: pciehp: Slot(108): Link Down

Summary
In the Linux kernel, the following vulnerability has been resolved:
mac802154: check local interfaces before deleting sdata list
syzkaller reported a corrupted list in ieee802154_if_remove. [1]

rdev_del_virtual_intf_deprecated list_del(&sdata->list)
ieee802154_if_remove
list_del_rcu
The net device has been unregistered, since the rcu grace period,
unregistration must be run before ieee802154_if_remove.
To avoid this issue, add a check for local->interfaces before deleting
sdata list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
geneve: fix header validation in geneve[6]_xmit_skb
syzbot is able to trigger an uninit-value in geneve_xmit() [1]
Problem : While most ip tunnel helpers (like ip_tunnel_get_dsfield())
uses skb_protocol(skb, true), pskb_inet_may_pull() is only using
skb->protocol.
If anything else than ETH_P_IPV6 or ETH_P_IP is found in skb->protocol,
pskb_inet_may_pull() does nothing at all.
If a vlan tag was provided by the caller (af_packet in the syzbot case),
the network header might not point to the correct location, and skb
linear part could be smaller than expected.
Add skb_vlan_inet_prepare() to perform a complete mac validation.
Use this in geneve for the moment, I suspect we need to adopt this
more broadly.
v4 - Jakub reported v3 broke l2_tos_ttl_inherit.sh selftest
- Only call __vlan_get_protocol() for vlan types.
v2,v3 - Addressed Sabrina comments on v1 and v2

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfs: Handle error of rpc_proc_register() in nfs_net_init().
syzkaller reported a warning [0] triggered while destroying immature
netns.
rpc_proc_register() was called in init_nfs_fs(), but its error
has been ignored since at least the initial commit 1da177e4c3f4
("Linux-2.6.12-rc2").
Recently, commit d47151b79e32 ("nfs: expose /proc/net/sunrpc/nfs
in net namespaces") converted the procfs to per-netns and made
the problem more visible.
Even when rpc_proc_register() fails, nfs_net_init() could succeed,
and thus nfs_net_exit() will be called while destroying the netns.
Then, remove_proc_entry() will be called for non-existing proc
directory and trigger the warning below.
Let's handle the error of rpc_proc_register() properly in nfs_net_init().

Summary
In the Linux kernel, the following vulnerability has been resolved:
xhci: handle isoc Babble and Buffer Overrun events properly
xHCI 4.9 explicitly forbids assuming that the xHC has released its
ownership of a multi-TRB TD when it reports an error on one of the
early TRBs. Yet the driver makes such assumption and releases the TD,
allowing the remaining TRBs to be freed or overwritten by new TDs.
The xHC should also report completion of the final TRB due to its IOC
flag being set by us, regardless of prior errors. This event cannot
be recognized if the TD has already been freed earlier, resulting in
"Transfer event TRB DMA ptr not part of current TD" error message.
Fix this by reusing the logic for processing isoc Transaction Errors.
This also handles hosts which fail to report the final completion.
Fix transfer length reporting on Babble errors. They may be caused by
device malfunction, no guarantee that the buffer has been filled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xdp: Remove WARN() from __xdp_reg_mem_model()
syzkaller reports a warning in __xdp_reg_mem_model().
The warning occurs only if __mem_id_init_hash_table() returns an error. It
returns the error in two cases:
1. memory allocation fails;
2. rhashtable_init() fails when some fields of rhashtable_params
struct are not initialized properly.
The second case cannot happen since there is a static const rhashtable_params
struct with valid fields. So, warning is only triggered when there is a
problem with memory allocation.
Thus, there is no sense in using WARN() to handle this error and it can be
safely removed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dpaa: Pad packets to ETH_ZLEN
When sending packets under 60 bytes, up to three bytes of the buffer
following the data may be leaked. Avoid this by extending all packets to
ETH_ZLEN, ensuring nothing is leaked in the padding. This bug can be
reproduced by running
$ ping -s 11 destination

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: core: Fix unremoved procfs host directory regression
Commit fc663711b944 ("scsi: core: Remove the /proc/scsi/${proc_name}
directory earlier") fixed a bug related to modules loading/unloading, by
adding a call to scsi_proc_hostdir_rm() on scsi_remove_host(). But that led
to a potential duplicate call to the hostdir_rm() routine, since it's also
called from scsi_host_dev_release(). That triggered a regression report,
which was then fixed by commit be03df3d4bfe ("scsi: core: Fix a procfs host
directory removal regression"). The fix just dropped the hostdir_rm() call
from dev_release().
But it happens that this proc directory is created on scsi_host_alloc(),
and that function "pairs" with scsi_host_dev_release(), while
scsi_remove_host() pairs with scsi_add_host(). In other words, it seems the
reason for removing the proc directory on dev_release() was meant to cover
cases in which a SCSI host structure was allocated, but the call to
scsi_add_host() didn't happen. And that pattern happens to exist in some
error paths, for example.
Syzkaller causes that by using USB raw gadget device, error'ing on
usb-storage driver, at usb_stor_probe2(). By checking that path, we can see
that the BadDevice label leads to a scsi_host_put() after a SCSI host
allocation, but there's no call to scsi_add_host() in such path. That leads
to messages like this in dmesg (and a leak of the SCSI host proc
structure):
usb-storage 4-1:87.51: USB Mass Storage device detected
proc_dir_entry 'scsi/usb-storage' already registered
WARNING: CPU: 1 PID: 3519 at fs/proc/generic.c:377 proc_register+0x347/0x4e0 fs/proc/generic.c:376
The proper fix seems to still call scsi_proc_hostdir_rm() on dev_release(),
but guard that with the state check for SHOST_CREATED; there is even a
comment in scsi_host_dev_release() detailing that: such conditional is
meant for cases where the SCSI host was allocated but there was no calls to
{add,remove}_host(), like the usb-storage case.
This is what we propose here and with that, the error path of usb-storage
does not trigger the warning anymore.

But that led\nto a potential duplicate call to the hostdir_rm() routine, since it\u0027s also\ncalled from scsi_host_dev_release(). That triggered a regression report,\nwhich was then fixed by commit be03df3d4bfe (\"scsi: core: Fix a procfs host\ndirectory removal regression\"). The fix just dropped the hostdir_rm() call\nfrom dev_release().\n\nBut it happens that this proc directory is created on scsi_host_alloc(),\nand that function \"pairs\" with scsi_host_dev_release(), while\nscsi_remove_host() pairs with scsi_add_host(). In other words, it seems the\nreason for removing the proc directory on dev_release() was meant to cover\ncases in which a SCSI host structure was allocated, but the call to\nscsi_add_host() didn\u0027t happen. And that pattern happens to exist in some\nerror paths, for example.\n\nSyzkaller causes that by using USB raw gadget device, error\u0027ing on\nusb-storage driver, at usb_stor_probe2(). By checking that path, we can see\nthat the BadDevice label leads to a scsi_host_put() after a SCSI host\nallocation, but there\u0027s no call to scsi_add_host() in such path. That leads\nto messages like this in dmesg (and a leak of the SCSI host proc\nstructure):\n\nusb-storage 4-1:87.51: USB Mass Storage device detected\nproc_dir_entry \u0027scsi/usb-storage\u0027 already registered\nWARNING: CPU: 1 PID: 3519 at fs/proc/generic.c:377 proc_register+0x347/0x4e0 fs/proc/generic.c:376\n\nThe proper fix seems to still call scsi_proc_hostdir_rm() on dev_release(),\nbut guard that with the state check for SHOST_CREATED; there is even a\ncomment in scsi_host_dev_release() detailing that: such conditional is\nmeant for cases where the SCSI host was allocated but there was no calls to\n{add,remove}_host(), like the usb-storage case.\n\nThis is what we propose here and with that, the error path of usb-storage\ndoes not trigger the warning anymore."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: fix use-after-free in taprio_change()
In 'taprio_change()', 'admin' pointer may become dangling due to sched
switch / removal caused by 'advance_sched()', and critical section
protected by 'q->current_entry_lock' is too small to prevent from such
a scenario (which causes use-after-free detected by KASAN). Fix this
by prefer 'rcu_replace_pointer()' over 'rcu_assign_pointer()' to update
'admin' immediately before an attempt to schedule freeing.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: bfa: Ensure the copied buf is NUL terminated
Currently, we allocate a nbytes-sized kernel buffer and copy nbytes from
userspace to that buffer. Later, we use sscanf on this buffer but we don't
ensure that the string is terminated inside the buffer, this can lead to
OOB read when using sscanf. Fix this issue by using memdup_user_nul instead
of memdup_user.

Summary
In the Linux kernel, the following vulnerability has been resolved:
leds: trigger: Unregister sysfs attributes before calling deactivate()
Triggers which have trigger specific sysfs attributes typically store
related data in trigger-data allocated by the activate() callback and
freed by the deactivate() callback.
Calling device_remove_groups() after calling deactivate() leaves a window
where the sysfs attributes show/store functions could be called after
deactivation and then operate on the just freed trigger-data.
Move the device_remove_groups() call to before deactivate() to close
this race window.
This also makes the deactivation path properly do things in reverse order
of the activation path which calls the activate() callback before calling
device_add_groups().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: add more sanity checks to qdisc_pkt_len_init()
One path takes care of SKB_GSO_DODGY, assuming
skb->len is bigger than hdr_len.
virtio_net_hdr_to_skb() does not fully dissect TCP headers,
it only make sure it is at least 20 bytes.
It is possible for an user to provide a malicious 'GSO' packet,
total length of 80 bytes.
- 20 bytes of IPv4 header
- 60 bytes TCP header
- a small gso_size like 8
virtio_net_hdr_to_skb() would declare this packet as a normal
GSO packet, because it would see 40 bytes of payload,
bigger than gso_size.
We need to make detect this case to not underflow
qdisc_skb_cb(skb)->pkt_len.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr
Although ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it
still means hlist_for_each_entry_rcu can return an item that got removed
from the list. The memory itself of such item is not freed thanks to RCU
but nothing guarantees the actual content of the memory is sane.
In particular, the reference count can be zero. This can happen if
ipv6_del_addr is called in parallel. ipv6_del_addr removes the entry
from inet6_addr_lst (hlist_del_init_rcu(&ifp->addr_lst)) and drops all
references (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough
timing, this can happen:
1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry.
2. Then, the whole ipv6_del_addr is executed for the given entry. The
reference count drops to zero and kfree_rcu is scheduled.
3. ipv6_get_ifaddr continues and tries to increments the reference count
(in6_ifa_hold).
4. The rcu is unlocked and the entry is freed.
5. The freed entry is returned.
Prevent increasing of the reference count in such case. The name
in6_ifa_hold_safe is chosen to mimic the existing fib6_info_hold_safe.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr\n\nAlthough ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it\nstill means hlist_for_each_entry_rcu can return an item that got removed\nfrom the list. The memory itself of such item is not freed thanks to RCU\nbut nothing guarantees the actual content of the memory is sane.\n\nIn particular, the reference count can be zero. This can happen if\nipv6_del_addr is called in parallel. ipv6_del_addr removes the entry\nfrom inet6_addr_lst (hlist_del_init_rcu(\u0026ifp-\u003eaddr_lst)) and drops all\nreferences (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough\ntiming, this can happen:\n\n1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry.\n\n2. Then, the whole ipv6_del_addr is executed for the given entry.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: battery: Fix possible crash when unregistering a battery hook
When a battery hook returns an error when adding a new battery, then
the battery hook is automatically unregistered.
However the battery hook provider cannot know that, so it will later
call battery_hook_unregister() on the already unregistered battery
hook, resulting in a crash.
Fix this by using the list head to mark already unregistered battery
hooks as already being unregistered so that they can be ignored by
battery_hook_unregister().

The first thread is walking the clk tree and calling
clk_pm_runtime_get() to power on devices required to read the clk
hardware via struct clk_ops::is_enabled(). This thread holds the clk
prepare_lock, and is trying to runtime PM resume a device, when it finds
that the device is in the process of resuming so the thread schedule()s
away waiting for the device to finish resuming before continuing. The
second thread is runtime PM resuming the same device, but the runtime
resume callback is calling clk_prepare(), trying to grab the
prepare_lock waiting on the first thread.
This is a classic ABBA deadlock. To properly fix the deadlock, we must
never runtime PM resume or suspend a device with the clk prepare_lock
held. Actually doing that is near impossible today because the global
prepare_lock would have to be dropped in the middle of the tree, the
device runtime PM resumed/suspended, and then the prepare_lock grabbed
again to ensure consistency of the clk tree topology. If anything
changes with the clk tree in the meantime, we've lost and will need to
start the operation all over again.
Luckily, most of the time we're simply incrementing or decrementing the
runtime PM count on an active device, so we don't have the chance to
schedule away with the prepare_lock held. Let's fix this immediate
problem that can be

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: Fix deadlock in ieee80211_sta_ps_deliver_wakeup()
The ieee80211_sta_ps_deliver_wakeup() function takes sta->ps_lock to
synchronizes with ieee80211_tx_h_unicast_ps_buf() which is called from
softirq context. However using only spin_lock() to get sta->ps_lock in
ieee80211_sta_ps_deliver_wakeup() does not prevent softirq to execute
on this same CPU, to run ieee80211_tx_h_unicast_ps_buf() and try to
take this same lock ending in deadlock. Below is an example of rcu stall
that arises in such situation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: accept TCA_STAB only for root qdisc
Most qdiscs maintain their backlog using qdisc_pkt_len(skb)
on the assumption it is invariant between the enqueue()
and dequeue() handlers.
Unfortunately syzbot can crash a host rather easily using
a TBF + SFQ combination, with an STAB on SFQ [1]
We can't support TCA_STAB on arbitrary level, this would
require to maintain per-qdisc storage.

[Analyze]
Task A set disconnect_flag = !0, which resulted in Task B's condition being met
and releasing mp, leading to this issue.
[Fix]
Place the disconnect_flag assignment operation after all code in pvr2_context_disconnect()
to avoid this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ecryptfs: Fix buffer size for tag 66 packet
The 'TAG 66 Packet Format' description is missing the cipher code and
checksum fields that are packed into the message packet. As a result,
the buffer allocated for the packet is 3 bytes too small and
write_tag_66_packet() will write up to 3 bytes past the end of the
buffer.
Fix this by increasing the size of the allocation so the whole packet
will always fit in the buffer.
This fixes the below kasan slab-out-of-bounds bug:
BUG: KASAN: slab-out-of-bounds in ecryptfs_generate_key_packet_set+0x7d6/0xde0

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout
While the rhashtable set gc runs asynchronously, a race allows it to
collect elements from anonymous sets with timeouts while it is being
released from the commit path.
Mingi Cho originally reported this issue in a different path in 6.1.x
with a pipapo set with low timeouts which is not possible upstream since
7395dfacfff6 ("netfilter: nf_tables: use timestamp to check for set
element timeout").
Fix this by setting on the dead flag for anonymous sets to skip async gc
in this case.
According to 08e4c8c5919f ("netfilter: nf_tables: mark newset as dead on
transaction abort"), Florian plans to accelerate abort path by releasing
objects via workqueue, therefore, this sets on the dead flag for abort
path too.

In the Linux kernel, the following vulnerability has been resolved:
ipv6: sr: fix invalid unregister error path
The error path of seg6_init() is wrong in case CONFIG_IPV6_SEG6_LWTUNNEL
is not defined. In that case if seg6_hmac_init() fails, the
genl_unregister_family() isn't called.
This issue exist since commit 46738b1317e1 ("ipv6: sr: add option to control
lwtunnel support"), and commit 5559cea2d5aa ("ipv6: sr: fix possible
use-after-free and null-ptr-deref") replaced unregister_pernet_subsys()
with genl_unregister_family() in this error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hrtimers: Handle CPU state correctly on hotplug
Consider a scenario where a CPU transitions from CPUHP_ONLINE to halfway
through a CPU hotunplug down to CPUHP_HRTIMERS_PREPARE, and then back to
CPUHP_ONLINE:
Since hrtimers_prepare_cpu() does not run, cpu_base.hres_active remains set
to 1 throughout. However, during a CPU unplug operation, the tick and the
clockevents are shut down at CPUHP_AP_TICK_DYING. On return to the online
state, for instance CFS incorrectly assumes that the hrtick is already
active, and the chance of the clockevent device to transition to oneshot
mode is also lost forever for the CPU, unless it goes back to a lower state
than CPUHP_HRTIMERS_PREPARE once.
This round-trip reveals another issue; cpu_base.online is not set to 1
after the transition, which appears as a WARN_ON_ONCE in enqueue_hrtimer().
Aside of that, the bulk of the per CPU state is not reset either, which
means there are dangling pointers in the worst case.
Address this by adding a corresponding startup() callback, which resets the
stale per CPU state and sets the online flag.
[ tglx: Make the new callback unconditionally available, remove the online
modification in the prepare() callback and clear the remaining
state in the starting callback instead of the prepare callback ]

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: delay all of ath9k_wmi_event_tasklet() until init is complete
The ath9k_wmi_event_tasklet() used in ath9k_htc assumes that all the data
structures have been fully initialised by the time it runs. However, because of
the order in which things are initialised, this is not guaranteed to be the
case, because the device is exposed to the USB subsystem before the ath9k driver
initialisation is completed.
We already committed a partial fix for this in commit:
8b3046abc99e ("ath9k_htc: fix NULL pointer dereference at ath9k_htc_tx_get_packet()")
However, that commit only aborted the WMI_TXSTATUS_EVENTID command in the event
tasklet, pairing it with an "initialisation complete" bit in the TX struct. It
seems syzbot managed to trigger the race for one of the other commands as well,
so let's just move the existing synchronisation bit to cover the whole
tasklet (setting it at the end of ath9k_htc_probe_device() instead of inside
ath9k_tx_init()).

Summary
In the Linux kernel, the following vulnerability has been resolved:
gpiolib: cdev: Fix use after free in lineinfo_changed_notify
The use-after-free issue occurs as follows: when the GPIO chip device file
is being closed by invoking gpio_chrdev_release(), watched_lines is freed
by bitmap_free(), but the unregistration of lineinfo_changed_nb notifier
chain failed due to waiting write rwsem. Additionally, one of the GPIO
chip's lines is also in the release process and holds the notifier chain's
read rwsem. Consequently, a race condition leads to the use-after-free of
watched_lines.
Here is the typical stack when issue happened:
[free]
gpio_chrdev_release()
--> bitmap_free(cdev->watched_lines) <-- freed
--> blocking_notifier_chain_unregister()
--> down_write(&nh->rwsem) <-- waiting rwsem
--> __down_write_common()
--> rwsem_down_write_slowpath()
--> schedule_preempt_disabled()
--> schedule()
[use]
st54spi_gpio_dev_release()
--> gpio_free()
--> gpiod_free()
--> gpiod_free_commit()
--> gpiod_line_state_notify()
--> blocking_notifier_call_chain()
--> down_read(&nh->rwsem); <-- held rwsem
--> notifier_call_chain()
--> lineinfo_changed_notify()
--> test_bit(xxxx, cdev->watched_lines) <-- use after free
The side effect of the use-after-free issue is that a GPIO line event is
being generated for userspace where it shouldn't. However, since the chrdev
is being closed, userspace won't have the chance to read that event anyway.
To fix the issue, call the bitmap_free() function after the unregistration
of lineinfo_changed_nb notifier chain.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sched: act_ct: take care of padding in struct zones_ht_key
Blamed commit increased lookup key size from 2 bytes to 16 bytes,
because zones_ht_key got a struct net pointer.
Make sure rhashtable_lookup() is not using the padding bytes
which are not initialized.

Summary
In the Linux kernel, the following vulnerability has been resolved:
of/irq: Prevent device address out-of-bounds read in interrupt map walk
When of_irq_parse_raw() is invoked with a device address smaller than
the interrupt parent node (from #address-cells property), KASAN detects
the following out-of-bounds read when populating the initial match table
(dyndbg="func of_irq_parse_* +p"):
OF: of_irq_parse_one: dev=/soc@0/picasso/watchdog, index=0
OF: parent=/soc@0/pci@878000000000/gpio0@17,0, intsize=2

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink()
The function ice_bridge_setlink() may encounter a NULL pointer dereference
if nlmsg_find_attr() returns NULL and br_spec is dereferenced subsequently
in nla_for_each_nested(). To address this issue, add a check to ensure that
br_spec is not NULL before proceeding with the nested attribute iteration.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fsnotify: clear PARENT_WATCHED flags lazily
In some setups directories can have many (usually negative) dentries.
Hence __fsnotify_update_child_dentry_flags() function can take a
significant amount of time. Since the bulk of this function happens
under inode->i_lock this causes a significant contention on the lock
when we remove the watch from the directory as the
__fsnotify_update_child_dentry_flags() call from fsnotify_recalc_mask()
races with __fsnotify_update_child_dentry_flags() calls from
__fsnotify_parent() happening on children. This can lead upto softlockup
reports reported by users.
Fix the problem by calling fsnotify_update_children_dentry_flags() to
set PARENT_WATCHED flags only when parent starts watching children.
When parent stops watching children, clear false positive PARENT_WATCHED
flags lazily in __fsnotify_parent() for each accessed child.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: gtp: Fix Use-After-Free in gtp_dellink
Since call_rcu, which is called in the hlist_for_each_entry_rcu traversal
of gtp_dellink, is not part of the RCU read critical section, it
is possible that the RCU grace period will pass during the traversal and
the key will be free.
To prevent this, it should be changed to hlist_for_each_entry_safe.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfs: fix UAF in direct writes
In production we have been hitting the following warning consistently
------------[ cut here ]------------
refcount_t: underflow; use-after-free.
WARNING: CPU: 17 PID: 1800359 at lib/refcount.c:28 refcount_warn_saturate+0x9c/0xe0
Workqueue: nfsiod nfs_direct_write_schedule_work [nfs]

? __btf_name_valid+0xa0/0xa0
ret_from_fork+0x1f/0x30
This is because we're completing the nfs_direct_request twice in a row.
The source of this is when we have our commit requests to submit, we
process them and send them off, and then in the completion path for the
commit requests we have
if (nfs_commit_end(cinfo.mds))
nfs_direct_write_complete(dreq);
However since we're submitting asynchronous requests we sometimes have
one that completes before we submit the next one, so we end up calling
complete on the nfs_direct_request twice.
The only other place we use nfs_generic_commit_list() is in
__nfs_commit_inode, which wraps this call in a
nfs_commit_begin();
nfs_commit_end();
Which is a common pattern for this style of completion handling, one
that is also repeated in the direct code with get_dreq()/put_dreq()
calls around where we process events as well as in the completion paths.
Fix this by using the same pattern for the commit requests.
Before with my 200 node rocksdb stress running this warning would pop
every 10ish minutes. With my patch the stress test has been running for
several hours without popping.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb-storage: alauda: Check whether the media is initialized
The member "uzonesize" of struct alauda_info will remain 0
if alauda_init_media() fails, potentially causing divide errors
in alauda_read_data() and alauda_write_lba().
- Add a member "media_initialized" to struct alauda_info.
- Change a condition in alauda_check_media() to ensure the
first initialization.
- Add an error check for the return value of alauda_init_media().

Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: core: Avoid negative index with array access
Commit 4d0c8d0aef63 ("mmc: core: Use mrq.sbc in close-ended ffu") assigns
prev_idata = idatas[i - 1], but doesn't check that the iterator i is
greater than zero. Let's fix this by adding a check.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: altmode should keep reference to parent
The altmode device release refers to its parent device, but without keeping
a reference to it.
When registering the altmode, get a reference to the parent and put it in
the release function.
Before this fix, when using CONFIG_DEBUG_KOBJECT_RELEASE, we see issues
like this:
[ 43.572860] kobject: 'port0.0' (ffff8880057ba008): kobject_release, parent 0000000000000000 (delayed 3000)

RDMA/srpt: Do not register event handler until srpt device is fully setup
Upon rare occasions, KASAN reports a use-after-free Write
in srpt_refresh_port().
This seems to be because an event handler is registered before the
srpt device is fully setup and a race condition upon error may leave a
partially setup event handler in place.
Instead, only register the event handler after srpt device initialization
is complete.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: sysctl: auth_enable: avoid using current->nsproxy
As mentioned in a previous commit of this series, using the 'net'
structure via 'current' is not recommended for different reasons:
- Inconsistency: getting info from the reader's/writer's netns vs only
from the opener's netns.
- current->nsproxy can be NULL in some cases, resulting in an 'Oops'
(null-ptr-deref), e.g. when the current task is exiting, as spotted by
syzbot [1] using acct(2).
The 'net' structure can be obtained from the table->data using
container_of().
Note that table->data could also be used directly, but that would
increase the size of this fix, while 'sctp.ctl_sock' still needs to be
retrieved from 'net' structure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_fs: Fix race between aio_cancel() and AIO request complete
FFS based applications can utilize the aio_cancel() callback to dequeue
pending USB requests submitted to the UDC. There is a scenario where the
FFS application issues an AIO cancel call, while the UDC is handling a
soft disconnect. For a DWC3 based implementation, the callstack looks
like the following:
DWC3 Gadget FFS Application
dwc3_gadget_soft_disconnect() ...
--> dwc3_stop_active_transfers()
--> dwc3_gadget_giveback(-ESHUTDOWN)
--> ffs_epfile_async_io_complete() ffs_aio_cancel()
--> usb_ep_free_request() --> usb_ep_dequeue()
There is currently no locking implemented between the AIO completion
handler and AIO cancel, so the issue occurs if the completion routine is
running in parallel to an AIO cancel call coming from the FFS application.
As the completion call frees the USB request (io_data->req) the FFS
application is also referencing it for the usb_ep_dequeue() call. This can
lead to accessing a stale/hanging pointer.
commit b566d38857fc ("usb: gadget: f_fs: use io_data->status consistently")
relocated the usb_ep_free_request() into ffs_epfile_async_io_complete().
However, in order to properly implement locking to mitigate this issue, the
spinlock can't be added to ffs_epfile_async_io_complete(), as
usb_ep_dequeue() (if successfully dequeuing a USB request) will call the
function driver's completion handler in the same context. Hence, leading
into a deadlock.
Fix this issue by moving the usb_ep_free_request() back to
ffs_user_copy_worker(), and ensuring that it explicitly sets io_data->req
to NULL after freeing it within the ffs->eps_lock. This resolves the race
condition above, as the ffs_aio_cancel() routine will not continue
attempting to dequeue a request that has already been freed, or the
ffs_user_copy_work() not freeing the USB request until the AIO cancel is
done referencing it.
This fix depends on
commit b566d38857fc ("usb: gadget: f_fs: use io_data->status
consistently")

Summary
In the Linux kernel, the following vulnerability has been resolved:
vsock/virtio: discard packets if the transport changes
If the socket has been de-assigned or assigned to another transport,
we must discard any packets received because they are not expected
and would cause issues when we access vsk->transport.
A possible scenario is described by Hyunwoo Kim in the attached link,
where after a first connect() interrupted by a signal, and a second
connect() failed, we can find `vsk->transport` at NULL, leading to a
NULL pointer dereference.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: fix possible race in __fib6_drop_pcpu_from()
syzbot found a race in __fib6_drop_pcpu_from() [1]
If compiler reads more than once (*ppcpu_rt),
second read could read NULL, if another cpu clears
the value in rt6_get_pcpu_route().
Add a READ_ONCE() to prevent this race.
Also add rcu_read_lock()/rcu_read_unlock() because
we rely on RCU protection while dereferencing pcpu_rt.
[1]

Summary
In the Linux kernel, the following vulnerability has been resolved:
ionic: fix use after netif_napi_del()
When queues are started, netif_napi_add() and napi_enable() are called.
If there are 4 queues and only 3 queues are used for the current
configuration, only 3 queues' napi should be registered and enabled.
The ionic_qcq_enable() checks whether the .poll pointer is not NULL for
enabling only the using queue' napi. Unused queues' napi will not be
registered by netif_napi_add(), so the .poll pointer indicates NULL.
But it couldn't distinguish whether the napi was unregistered or not
because netif_napi_del() doesn't reset the .poll pointer to NULL.
So, ionic_qcq_enable() calls napi_enable() for the queue, which was
unregistered by netif_napi_del().
Reproducer:
ethtool -L <interface name> rx 1 tx 1 combined 0
ethtool -L <interface name> rx 0 tx 0 combined 1
ethtool -L <interface name> rx 0 tx 0 combined 4
Splat looks like:

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: fix overwriting ct original tuple for ICMPv6
OVS_PACKET_CMD_EXECUTE has 3 main attributes:
- OVS_PACKET_ATTR_KEY - Packet metadata in a netlink format.
- OVS_PACKET_ATTR_PACKET - Binary packet content.
- OVS_PACKET_ATTR_ACTIONS - Actions to execute on the packet.
OVS_PACKET_ATTR_KEY is parsed first to populate sw_flow_key structure
with the metadata like conntrack state, input port, recirculation id,
etc. Then the packet itself gets parsed to populate the rest of the
keys from the packet headers.
Whenever the packet parsing code starts parsing the ICMPv6 header, it
first zeroes out fields in the key corresponding to Neighbor Discovery
information even if it is not an ND packet.
It is an 'ipv6.nd' field. However, the 'ipv6' is a union that shares
the space between 'nd' and 'ct_orig' that holds the original tuple
conntrack metadata parsed from the OVS_PACKET_ATTR_KEY.
ND packets should not normally have conntrack state, so it's fine to
share the space, but normal ICMPv6 Echo packets or maybe other types of
ICMPv6 can have the state attached and it should not be overwritten.
The issue results in all but the last 4 bytes of the destination
address being wiped from the original conntrack tuple leading to
incorrect packet matching and potentially executing wrong actions
in case this packet recirculates within the datapath or goes back
to userspace.
ND fields should not be accessed in non-ND packets, so not clearing
them should be fine. Executing memset() only for actual ND packets to
avoid the issue.
Initializing the whole thing before parsing is needed because ND packet
may not contain all the options.
The issue only affects the OVS_PACKET_CMD_EXECUTE path and doesn't
affect packets entering OVS datapath from network interfaces, because
in this case CT metadata is populated from skb after the packet is
already parsed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qedf: Ensure the copied buf is NUL terminated
Currently, we allocate a count-sized kernel buffer and copy count from
userspace to that buffer. Later, we use kstrtouint on this buffer but we
don't ensure that the string is terminated inside the buffer, this can
lead to OOB read when using kstrtouint. Fix this issue by using
memdup_user_nul instead of memdup_user.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix corruption during on-line resize
We observed a corruption during on-line resize of a file system that is
larger than 16 TiB with 4k block size. With having more then 2^32 blocks
resize_inode is turned off by default by mke2fs. The issue can be
reproduced on a smaller file system for convenience by explicitly
turning off resize_inode. An on-line resize across an 8 GiB boundary (the
size of a meta block group in this setup) then leads to a corruption:
dev=/dev/<some_dev> # should be >= 16 GiB
mkdir -p /corruption
/sbin/mke2fs -t ext4 -b 4096 -O ^resize_inode $dev $((2 * 2**21 - 2**15))
mount -t ext4 $dev /corruption
dd if=/dev/zero bs=4096 of=/corruption/test count=$((2*2**21 - 4*2**15))
sha1sum /corruption/test
# 79d2658b39dcfd77274e435b0934028adafaab11 /corruption/test
/sbin/resize2fs $dev $((2*2**21))
# drop page cache to force reload the block from disk
echo 1 > /proc/sys/vm/drop_caches
sha1sum /corruption/test
# 3c2abc63cbf1a94c9e6977e0fbd72cd832c4d5c3 /corruption/test
2^21 = 2^15*2^6 equals 8 GiB whereof 2^15 is the number of blocks per
block group and 2^6 are the number of block groups that make a meta
block group.
The last checksum might be different depending on how the file is laid
out across the physical blocks. The actual corruption occurs at physical
block 63*2^15 = 2064384 which would be the location of the backup of the
meta block group's block descriptor. During the on-line resize the file
system will be converted to meta_bg starting at s_first_meta_bg which is
2 in the example - meaning all block groups after 16 GiB. However, in
ext4_flex_group_add we might add block groups that are not part of the
first meta block group yet. In the reproducer we achieved this by
substracting the size of a whole block group from the point where the
meta block group would start. This must be considered when updating the
backup block group descriptors to follow the non-meta_bg layout. The fix
is to add a test whether the group to add is already part of the meta
block group or not.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: fix corruption during on-line resize\n\nWe observed a corruption during on-line resize of a file system that is\nlarger than 16 TiB with 4k block size. With having more then 2^32 blocks\nresize_inode is turned off by default by mke2fs. The issue can be\nreproduced on a smaller file system for convenience by explicitly\nturning off resize_inode. An on-line resize across an 8 GiB boundary (the\nsize of a meta block group in this setup) then leads to a corruption:\n\n dev=/dev/\u003csome_dev\u003e # should be \u003e= 16 GiB\n mkdir -p /corruption\n /sbin/mke2fs -t ext4 -b 4096 -O ^resize_inode $dev $((2 * 2**21 - 2**15))\n mount -t ext4 $dev /corruption\n\n dd if=/dev/zero bs=4096 of=/corruption/test count=$((2*2**21 - 4*2**15))\n sha1sum /corruption/test\n # 79d2658b39dcfd77274e435b0934028adafaab11 /corruption/test\n\n /sbin/resize2fs $dev $((2*2**21))\n # drop page cache to force reload the block from disk\n echo 1 \u003e /proc/sys/vm/drop_caches\n\n sha1sum /corruption/test\n # 3c2abc63cbf1a94c9e6977e0fbd72cd832c4d5c3 /corruption/test\n\n2^21 = 2^15*2^6 equals 8 GiB whereof 2^15 is the number of blocks per\nblock group and 2^6 are the number of block groups that make a meta\nblock group.\n\nThe last checksum might be different depending on how the file is laid\nout across the physical blocks. The actual corruption occurs at physical\nblock 63*2^15 = 2064384 which would be the location of the backup of the\nmeta block group\u0027s block descriptor. During the on-line resize the file\nsystem will be converted to meta_bg starting at s_first_meta_bg which is\n2 in the example - meaning all block groups after 16 GiB. However, in\next4_flex_group_add we might add block groups that are not part of the\nfirst meta block group yet. In the reproducer we achieved this by\nsubstracting the size of a whole block group from the point where the\nmeta block group would start. This must be considered when updating the\nbackup block group descriptors to follow the non-meta_bg layout. The fix\nis to add a test whether the group to add is already part of the meta\nblock group or not."

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conntrack_h323: Add protection for bmp length out of range
UBSAN load reports an exception of BRK#5515 SHIFT_ISSUE:Bitwise shifts
that are out of bounds for their data type.
vmlinux get_bitmap(b=75) + 712
<net/netfilter/nf_conntrack_h323_asn1.c:0>
vmlinux decode_seq(bs=0xFFFFFFD008037000, f=0xFFFFFFD008037018, level=134443100) + 1956
<net/netfilter/nf_conntrack_h323_asn1.c:592>
vmlinux decode_choice(base=0xFFFFFFD0080370F0, level=23843636) + 1216
<net/netfilter/nf_conntrack_h323_asn1.c:814>
vmlinux decode_seq(f=0xFFFFFFD0080371A8, level=134443500) + 812
<net/netfilter/nf_conntrack_h323_asn1.c:576>
vmlinux decode_choice(base=0xFFFFFFD008037280, level=0) + 1216
<net/netfilter/nf_conntrack_h323_asn1.c:814>
vmlinux DecodeRasMessage() + 304
<net/netfilter/nf_conntrack_h323_asn1.c:833>
vmlinux ras_help() + 684
<net/netfilter/nf_conntrack_h323_main.c:1728>
vmlinux nf_confirm() + 188
<net/netfilter/nf_conntrack_proto.c:137>
Due to abnormal data in skb->data, the extension bitmap length
exceeds 32 when decoding ras message then uses the length to make
a shift operation. It will change into negative after several loop.
UBSAN load could detect a negative shift as an undefined behaviour
and reports exception.
So we add the protection to avoid the length exceeding 32. Or else
it will return out of range error and stop decoding.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix overflow in get_free_elt()
"tracing_map->next_elt" in get_free_elt() is at risk of overflowing.
Once it overflows, new elements can still be inserted into the tracing_map
even though the maximum number of elements (`max_elts`) has been reached.
Continuing to insert elements after the overflow could result in the
tracing_map containing "tracing_map->max_size" elements, leaving no empty
entries.
If any attempt is made to insert an element into a full tracing_map using
`__tracing_map_insert()`, it will cause an infinite loop with preemption
disabled, leading to a CPU hang problem.
Fix this by preventing any further increments to "tracing_map->next_elt"
once it reaches "tracing_map->max_elt".

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: fix RELEASE_LOCKOWNER
The test on so_count in nfsd4_release_lockowner() is nonsense and
harmful. Revert to using check_for_locks(), changing that to not sleep.
First: harmful.
As is documented in the kdoc comment for nfsd4_release_lockowner(), the
test on so_count can transiently return a false positive resulting in a
return of NFS4ERR_LOCKS_HELD when in fact no locks are held. This is
clearly a protocol violation and with the Linux NFS client it can cause
incorrect behaviour.
If RELEASE_LOCKOWNER is sent while some other thread is still
processing a LOCK request which failed because, at the time that request
was received, the given owner held a conflicting lock, then the nfsd
thread processing that LOCK request can hold a reference (conflock) to
the lock owner that causes nfsd4_release_lockowner() to return an
incorrect error.
The Linux NFS client ignores that NFS4ERR_LOCKS_HELD error because it
never sends NFS4_RELEASE_LOCKOWNER without first releasing any locks, so
it knows that the error is impossible. It assumes the lock owner was in
fact released so it feels free to use the same lock owner identifier in
some later locking request.
When it does reuse a lock owner identifier for which a previous RELEASE
failed, it will naturally use a lock_seqid of zero. However the server,
which didn't release the lock owner, will expect a larger lock_seqid and
so will respond with NFS4ERR_BAD_SEQID.
So clearly it is harmful to allow a false positive, which testing
so_count allows.
The test is nonsense because ... well... it doesn't mean anything.
so_count is the sum of three different counts.
1/ the set of states listed on so_stateids
2/ the set of active vfs locks owned by any of those states
3/ various transient counts such as for conflicting locks.
When it is tested against '2' it is clear that one of these is the
transient reference obtained by find_lockowner_str_locked(). It is not
clear what the other one is expected to be.
In practice, the count is often 2 because there is precisely one state
on so_stateids. If there were more, this would fail.
In my testing I see two circumstances when RELEASE_LOCKOWNER is called.
In one case, CLOSE is called before RELEASE_LOCKOWNER. That results in
all the lock states being removed, and so the lockowner being discarded
(it is removed when there are no more references which usually happens
when the lock state is discarded). When nfsd4_release_lockowner() finds
that the lock owner doesn't exist, it returns success.
The other case shows an so_count of '2' and precisely one state listed
in so_stateid. It appears that the Linux client uses a separate lock
owner for each file resulting in one lock state per lock owner, so this
test on '2' is safe. For another client it might not be safe.
So this patch changes check_for_locks() to use the (newish)
find_any_file_locked() so that it doesn't take a reference on the
nfs4_file and so never calls nfsd_file_put(), and so never sleeps. With
this check is it safe to restore the use of check_for_locks() rather
than testing so_count against the mysterious '2'.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio/pci: Create persistent INTx handler
A vulnerability exists where the eventfd for INTx signaling can be
deconfigured, which unregisters the IRQ handler but still allows
eventfds to be signaled with a NULL context through the SET_IRQS ioctl
or through unmask irqfd if the device interrupt is pending.
Ideally this could be solved with some additional locking; the igate
mutex serializes the ioctl and config space accesses, and the interrupt
handler is unregistered relative to the trigger, but the irqfd path
runs asynchronous to those. The igate mutex cannot be acquired from the
atomic context of the eventfd wake function. Disabling the irqfd
relative to the eventfd registration is potentially incompatible with
existing userspace.
As a result, the solution implemented here moves configuration of the
INTx interrupt handler to track the lifetime of the INTx context object
and irq_type configuration, rather than registration of a particular
trigger eventfd. Synchronization is added between the ioctl path and
eventfd_signal() wrapper such that the eventfd trigger can be
dynamically updated relative to in-flight interrupts or irqfd callbacks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/proc: fix softlockup in __read_vmcore (part 2)
Since commit 5cbcb62dddf5 ("fs/proc: fix softlockup in __read_vmcore") the
number of softlockups in __read_vmcore at kdump time have gone down, but
they still happen sometimes.
In a memory constrained environment like the kdump image, a softlockup is
not just a harmless message, but it can interfere with things like RCU
freeing memory, causing the crashdump to get stuck.
The second loop in __read_vmcore has a lot more opportunities for natural
sleep points, like scheduling out while waiting for a data write to
happen, but apparently that is not always enough.
Add a cond_resched() to the second loop in __read_vmcore to (hopefully)
get rid of the softlockups.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: sch_multiq: fix possible OOB write in multiq_tune()
q->bands will be assigned to qopt->bands to execute subsequent code logic
after kmalloc. So the old q->bands should not be used in kmalloc.
Otherwise, an out-of-bounds write will occur.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix array out-of-bound access in SoC stats
Currently, the ath11k_soc_dp_stats::hal_reo_error array is defined with a
maximum size of DP_REO_DST_RING_MAX. However, the ath11k_dp_process_rx()
function access ath11k_soc_dp_stats::hal_reo_error using the REO
destination SRNG ring ID, which is incorrect. SRNG ring ID differ from
normal ring ID, and this usage leads to out-of-bounds array access. To fix
this issue, modify ath11k_dp_process_rx() to use the normal ring ID
directly instead of the SRNG ring ID to avoid out-of-bounds array access.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: always wait for both firmware loading attempts
In 'rtw_wait_firmware_completion()', always wait for both (regular and
wowlan) firmware loading attempts. Otherwise if 'rtw_usb_intf_init()'
has failed in 'rtw_usb_probe()', 'rtw_usb_disconnect()' may issue
'ieee80211_free_hw()' when one of 'rtw_load_firmware_cb()' (usually
the wowlan one) is still in progress, causing UAF detected by KASAN.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: bcm: Clear bo->bcm_proc_read after remove_proc_entry().
syzbot reported a warning in bcm_release(). [0]
The blamed change fixed another warning that is triggered when
connect() is issued again for a socket whose connect()ed device has
been unregistered.
However, if the socket is just close()d without the 2nd connect(), the
remaining bo->bcm_proc_read triggers unnecessary remove_proc_entry()
in bcm_release().
Let's clear bo->bcm_proc_read after remove_proc_entry() in bcm_notify().

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix hashtab overflow check on 32-bit arches
The hashtab code relies on roundup_pow_of_two() to compute the number of
hash buckets, and contains an overflow check by checking if the
resulting value is 0. However, on 32-bit arches, the roundup code itself
can overflow by doing a 32-bit left-shift of an unsigned long value,
which is undefined behaviour, so it is not guaranteed to truncate
neatly. This was triggered by syzbot on the DEVMAP_HASH type, which
contains the same check, copied from the hashtab code. So apply the same
fix to hashtab, by moving the overflow check to before the roundup.

However, on 32-bit arches, the roundup code itself\ncan overflow by doing a 32-bit left-shift of an unsigned long value,\nwhich is undefined behaviour, so it is not guaranteed to truncate\nneatly. This was triggered by syzbot on the DEVMAP_HASH type, which\ncontains the same check, copied from the hashtab code. So apply the same\nfix to hashtab, by moving the overflow check to before the roundup."

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: remove clear SB_INLINECRYPT flag in default_options
In f2fs_remount, SB_INLINECRYPT flag will be clear and re-set.
If create new file or open file during this gap, these files
will not use inlinecrypt. Worse case, it may lead to data
corruption if wrappedkey_v0 is enable.
Thread A: Thread B:
-f2fs_remount -f2fs_file_open or f2fs_new_inode
-default_options
<- clear SB_INLINECRYPT flag
-fscrypt_select_encryption_impl
-parse_options
<- set SB_INLINECRYPT again

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/iucv: Avoid explicit cpumask var allocation on stack
For CONFIG_CPUMASK_OFFSTACK=y kernel, explicit allocation of cpumask
variable on stack is not recommended since it can cause potential stack
overflow.
Instead, kernel code should always use *cpumask_var API(s) to allocate
cpumask var in config-neutral way, leaving allocation strategy to
CONFIG_CPUMASK_OFFSTACK.
Use *cpumask_var API(s) to address it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: Fix Use-After-Free in ovs_ct_exit
Since kfree_rcu, which is called in the hlist_for_each_entry_rcu traversal
of ovs_ct_limit_exit, is not part of the RCU read critical section, it
is possible that the RCU grace period will pass during the traversal and
the key will be free.
To prevent this, it should be changed to hlist_for_each_entry_safe.

Summary
In the Linux kernel, the following vulnerability has been resolved:
init/main.c: Fix potential static_command_line memory overflow
We allocate memory of size 'xlen + strlen(boot_command_line) + 1' for
static_command_line, but the strings copied into static_command_line are
extra_command_line and command_line, rather than extra_command_line and
boot_command_line.
When strlen(command_line) > strlen(boot_command_line), static_command_line
will overflow.
This patch just recovers strlen(command_line) which was miss-consolidated
with strlen(boot_command_line) in the commit f5c7310ac73e ("init/main: add
checks for the return value of memblock_alloc*()")

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Fix ia_size underflow
iattr::ia_size is a loff_t, which is a signed 64-bit type. NFSv3 and
NFSv4 both define file size as an unsigned 64-bit type. Thus there
is a range of valid file size values an NFS client can send that is
already larger than Linux can handle.
Currently decode_fattr4() dumps a full u64 value into ia_size. If
that value happens to be larger than S64_MAX, then ia_size
underflows. I'm about to fix up the NFSv3 behavior as well, so let's
catch the underflow in the common code path: nfsd_setattr().

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Fix data races in unix_release_sock/unix_stream_sendmsg
A data-race condition has been identified in af_unix. In one data path,
the write function unix_release_sock() atomically writes to
sk->sk_shutdown using WRITE_ONCE. However, on the reader side,
unix_stream_sendmsg() does not read it atomically. Consequently, this
issue is causing the following KCSAN splat to occur:
BUG: KCSAN: data-race in unix_release_sock / unix_stream_sendmsg
write (marked) to 0xffff88867256ddbb of 1 bytes by task 7270 on cpu 28:

entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:130)
value changed: 0x01 -> 0x03
The line numbers are related to commit dd5a440a31fa ("Linux 6.9-rc7").
Commit e1d09c2c2f57 ("af_unix: Fix data races around sk->sk_shutdown.")
addressed a comparable issue in the past regarding sk->sk_shutdown.
However, it overlooked resolving this particular data path.
This patch only offending unix_stream_sendmsg() function, since the
other reads seem to be protected by unix_state_lock() as discussed in

Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: sysctl: cookie_hmac_alg: avoid using current->nsproxy
As mentioned in a previous commit of this series, using the 'net'
structure via 'current' is not recommended for different reasons:
- Inconsistency: getting info from the reader's/writer's netns vs only
from the opener's netns.
- current->nsproxy can be NULL in some cases, resulting in an 'Oops'
(null-ptr-deref), e.g. when the current task is exiting, as spotted by
syzbot [1] using acct(2).
The 'net' structure can be obtained from the table->data using
container_of().
Note that table->data could also be used directly, as this is the only
member needed from the 'net' structure, but that would increase the size
of this fix, to use '*data' everywhere 'net->sctp.sctp_hmac_alg' is
used.

Summary
In the Linux kernel, the following vulnerability has been resolved:
security/keys: fix slab-out-of-bounds in key_task_permission
KASAN reports an out of bounds read:

This issue was also reported by syzbot.
It can be reproduced by following these steps(more details [1]):
1. Obtain more than 32 inputs that have similar hashes, which ends with the
pattern '0xxxxxxxe6'.
2. Reboot and add the keys obtained in step 1.
The reproducer demonstrates how this issue happened:
1. In the search_nested_keyrings function, when it iterates through the
slots in a node(below tag ascend_to_node), if the slot pointer is meta
and node->back_pointer != NULL(it means a root), it will proceed to
descend_to_node. However, there is an exception. If node is the root,
and one of the slots points to a shortcut, it will be treated as a
keyring.
2. Whether the ptr is keyring decided by keyring_ptr_is_keyring function.
However, KEYRING_PTR_SUBTYPE is 0x2UL, the same as
ASSOC_ARRAY_PTR_SUBTYPE_MASK.
3. When 32 keys with the similar hashes are added to the tree, the ROOT
has keys with hashes that are not similar (e.g. slot 0) and it splits
NODE A without using a shortcut. When NODE A is filled with keys that
all hashes are xxe6, the keys are similar, NODE A will split with a
shortcut. Finally, it forms the tree as shown below, where slot 6 points
to a shortcut.

4. As mentioned above, If a slot(slot 6) of the root points to a shortcut,
it may be mistakenly transferred to a key*, leading to a read
out-of-bounds read.
To fix this issue, one should jump to descend_to_node if the ptr is a
shortcut, regardless of whether the node is root or not.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: avoid use-after-free in ext4_ext_show_leaf()
In ext4_find_extent(), path may be freed by error or be reallocated, so
using a previously saved *ppath may have been freed and thus may trigger
use-after-free, as follows:
ext4_split_extent
path = *ppath;
ext4_split_extent_at(ppath)
path = ext4_find_extent(ppath)
ext4_split_extent_at(ppath)
// ext4_find_extent fails to free path
// but zeroout succeeds
ext4_ext_show_leaf(inode, path)
eh = path[depth].p_hdr
// path use-after-free !!!
Similar to ext4_split_extent_at(), we use *ppath directly as an input to
ext4_ext_show_leaf(). Fix a spelling error by the way.
Same problem in ext4_ext_handle_unwritten_extents(). Since 'path' is only
used in ext4_ext_show_leaf(), remove 'path' and use *ppath directly.
This issue is triggered only when EXT_DEBUG is defined and therefore does
not affect functionality.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak
Using completion_done to determine whether the caller has gone
away only works after a complete call. Furthermore it's still
possible that the caller has not yet called wait_for_completion,
resulting in another potential UAF.
Fix this by making the caller use cancel_work_sync and then freeing
the memory safely.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv4: ip_tunnel: Fix suspicious RCU usage warning in ip_tunnel_init_flow()
There are code paths from which the function is called without holding
the RCU read lock, resulting in a suspicious RCU usage warning [1].
Fix by using l3mdev_master_upper_ifindex_by_index() which will acquire
the RCU read lock before calling
l3mdev_master_upper_ifindex_by_index_rcu().
[1]

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: dax: fix overflowing extents beyond inode size when partially writing
The dax_iomap_rw() does two things in each iteration: map written blocks
and copy user data to blocks. If the process is killed by user(See signal
handling in dax_iomap_iter()), the copied data will be returned and added
on inode size, which means that the length of written extents may exceed
the inode size, then fsck will fail. An example is given as:
dd if=/dev/urandom of=file bs=4M count=1
dax_iomap_rw
iomap_iter // round 1
ext4_iomap_begin
ext4_iomap_alloc // allocate 0~2M extents(written flag)
dax_iomap_iter // copy 2M data
iomap_iter // round 2
iomap_iter_advance
iter->pos += iter->processed // iter->pos = 2M
ext4_iomap_begin
ext4_iomap_alloc // allocate 2~4M extents(written flag)
dax_iomap_iter
fatal_signal_pending
done = iter->pos - iocb->ki_pos // done = 2M
ext4_handle_inode_extension
ext4_update_inode_size // inode size = 2M
fsck reports: Inode 13, i_size is 2097152, should be 4194304. Fix?
Fix the problem by truncating extents if the written length is smaller
than expected.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kobject_uevent: Fix OOB access within zap_modalias_env()
zap_modalias_env() wrongly calculates size of memory block to move, so
will cause OOB memory access issue if variable MODALIAS is not the last
one within its @env parameter, fixed by correcting size to memmove.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: carl9170: add a proper sanity check for endpoints
Syzkaller reports [1] hitting a warning which is caused by presence
of a wrong endpoint type at the URB sumbitting stage. While there
was a check for a specific 4th endpoint, since it can switch types
between bulk and interrupt, other endpoints are trusted implicitly.
Similar warning is triggered in a couple of other syzbot issues [2].
Fix the issue by doing a comprehensive check of all endpoints
taking into account difference between high- and full-speed
configuration.
[1] Syzkaller report:
...

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Initialize get_bytes_per_element's default to 1
Variables, used as denominators and maybe not assigned to other values,
should not be 0. bytes_per_element_y & bytes_per_element_c are
initialized by get_bytes_per_element() which should never return 0.
This fixes 10 DIVIDE_BY_ZERO issues reported by Coverity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Protect against int overflow for stack access size
This patch re-introduces protection against the size of access to stack
memory being negative; the access size can appear negative as a result
of overflowing its signed int representation. This should not actually
happen, as there are other protections along the way, but we should
protect against it anyway. One code path was missing such protections
(fixed in the previous patch in the series), causing out-of-bounds array
accesses in check_stack_range_initialized(). This patch causes the
verification of a program with such a non-sensical access size to fail.
This check used to exist in a more indirect way, but was inadvertendly
removed in a833a17aeac7.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: i2c-hid: remove I2C_HID_READ_PENDING flag to prevent lock-up
The flag I2C_HID_READ_PENDING is used to serialize I2C operations.
However, this is not necessary, because I2C core already has its own
locking for that.
More importantly, this flag can cause a lock-up: if the flag is set in
i2c_hid_xfer() and an interrupt happens, the interrupt handler
(i2c_hid_irq) will check this flag and return immediately without doing
anything, then the interrupt handler will be invoked again in an
infinite loop.
Since interrupt handler is an RT task, it takes over the CPU and the
flag-clearing task never gets scheduled, thus we have a lock-up.
Delete this unnecessary flag.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: Fix use-after-free bug in brcmf_cfg80211_detach
This is the candidate patch of CVE-2023-47233 :
https://nvd.nist.gov/vuln/detail/CVE-2023-47233
In brcm80211 driver,it starts with the following invoking chain
to start init a timeout worker:
->brcmf_usb_probe
->brcmf_usb_probe_cb
->brcmf_attach
->brcmf_bus_started
->brcmf_cfg80211_attach
->wl_init_priv
->brcmf_init_escan
->INIT_WORK(&cfg->escan_timeout_work,
brcmf_cfg80211_escan_timeout_worker);
If we disconnect the USB by hotplug, it will call
brcmf_usb_disconnect to make cleanup. The invoking chain is :
brcmf_usb_disconnect
->brcmf_usb_disconnect_cb
->brcmf_detach
->brcmf_cfg80211_detach
->kfree(cfg);
While the timeout woker may still be running. This will cause
a use-after-free bug on cfg in brcmf_cfg80211_escan_timeout_worker.
Fix it by deleting the timer and canceling the worker in
brcmf_cfg80211_detach.
[arend.vanspriel@broadcom.com: keep timer delete as is and cancel work just before free]

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes
When moving a station out of a VLAN and deleting the VLAN afterwards, the
fast_rx entry still holds a pointer to the VLAN's netdev, which can cause
use-after-free bugs. Fix this by immediately calling ieee80211_check_fast_rx
after the VLAN change.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: prevent nf_skb_duplicated corruption
syzbot found that nf_dup_ipv4() or nf_dup_ipv6() could write
per-cpu variable nf_skb_duplicated in an unsafe way [1].
Disabling preemption as hinted by the splat is not enough,
we have to disable soft interrupts as well.
[1]
BUG: using __this_cpu_write() in preemptible [00000000] code: syz.4.282/6316

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix out-of-bounds write in trie_get_next_key()
trie_get_next_key() allocates a node stack with size trie->max_prefixlen,
while it writes (trie->max_prefixlen + 1) nodes to the stack when it has
full paths from the root to leaves. For example, consider a trie with
max_prefixlen is 8, and the nodes with key 0x00/0, 0x00/1, 0x00/2, ...
0x00/8 inserted. Subsequent calls to trie_get_next_key with _key with
.prefixlen = 8 make 9 nodes be written on the node stack with size 8.

Summary
In the Linux kernel, the following vulnerability has been resolved:
exec: Fix ToCToU between perm check and set-uid/gid usage
When opening a file for exec via do_filp_open(), permission checking is
done against the file's metadata at that moment, and on success, a file
pointer is passed back. Much later in the execve() code path, the file
metadata (specifically mode, uid, and gid) is used to determine if/how
to set the uid and gid. However, those values may have changed since the
permissions check, meaning the execution may gain unintended privileges.
For example, if a file could change permissions from executable and not
set-id:
---------x 1 root root 16048 Aug 7 13:16 target
to set-id and non-executable:
---S------ 1 root root 16048 Aug 7 13:16 target
it is possible to gain root privileges when execution should have been
disallowed.
While this race condition is rare in real-world scenarios, it has been
observed (and proven exploitable) when package managers are updating
the setuid bits of installed programs. Such files start with being
world-executable but then are adjusted to be group-exec with a set-uid
bit. For example, "chmod o-x,u+s target" makes "target" executable only
by uid "root" and gid "cdrom", while also becoming setuid-root:
-rwxr-xr-x 1 root cdrom 16048 Aug 7 13:16 target
becomes:
-rwsr-xr-- 1 root cdrom 16048 Aug 7 13:16 target
But racing the chmod means users without group "cdrom" membership can
get the permission to execute "target" just before the chmod, and when
the chmod finishes, the exec reaches brpm_fill_uid(), and performs the
setuid to root, violating the expressed authorization of "only cdrom
group members can setuid to root".
Re-check that we still have execute permissions in case the metadata
has changed. It would be better to keep a copy from the perm-check time,
but until we can do that refactoring, the least-bad option is to do a
full inode_permission() call (under inode lock). It is understood that
this is safe against dead-locks, but hardly optimal.

Much later in the execve() code path, the file\nmetadata (specifically mode, uid, and gid) is used to determine if/how\nto set the uid and gid. However, those values may have changed since the\npermissions check, meaning the execution may gain unintended privileges.\n\nFor example, if a file could change permissions from executable and not\nset-id:\n\n---------x 1 root root 16048 Aug 7 13:16 target\n\nto set-id and non-executable:\n\n---S------ 1 root root 16048 Aug 7 13:16 target\n\nit is possible to gain root privileges when execution should have been\ndisallowed.\n\nWhile this race condition is rare in real-world scenarios, it has been\nobserved (and proven exploitable) when package managers are updating\nthe setuid bits of installed programs. Such files start with being\nworld-executable but then are adjusted to be group-exec with a set-uid\nbit. For example, \"chmod o-x,u+s target\" makes \"target\" executable only\nby uid \"root\" and gid \"cdrom\", while also becoming setuid-root:\n\n-rwxr-xr-x 1 root cdrom 16048 Aug 7 13:16 target\n\nbecomes:\n\n-rwsr-xr-- 1 root cdrom 16048 Aug 7 13:16 target\n\nBut racing the chmod means users without group \"cdrom\" membership can\nget the permission to execute \"target\" just before the chmod, and when\nthe chmod finishes, the exec reaches brpm_fill_uid(), and performs the\nsetuid to root, violating the expressed authorization of \"only cdrom\ngroup members can setuid to root\".\n\nRe-check that we still have execute permissions in case the metadata\nhas changed. It would be better to keep a copy from the perm-check time,\nbut until we can do that refactoring, the least-bad option is to do a\nfull inode_permission() call (under inode lock). It is understood that\nthis is safe against dead-locks, but hardly optimal."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/bnx2x: Prevent access to a freed page in page_pool
Fix race condition leading to system crash during EEH error handling
During EEH error recovery, the bnx2x driver's transmit timeout logic
could cause a race condition when handling reset tasks. The
bnx2x_tx_timeout() schedules reset tasks via bnx2x_sp_rtnl_task(),
which ultimately leads to bnx2x_nic_unload(). In bnx2x_nic_unload()
SGEs are freed using bnx2x_free_rx_sge_range(). However, this could
overlap with the EEH driver's attempt to reset the device using
bnx2x_io_slot_reset(), which also tries to free SGEs. This race
condition can result in system crashes due to accessing freed memory
locations in bnx2x_free_rx_sge()
799 static inline void bnx2x_free_rx_sge(struct bnx2x *bp,
800 struct bnx2x_fastpath *fp, u16 index)
801 {
802 struct sw_rx_page *sw_buf = &fp->rx_page_ring[index];
803 struct page *page = sw_buf->page;
....
where sw_buf was set to NULL after the call to dma_unmap_page()
by the preceding thread.

To solve this issue, we need to verify page pool allocations before
freeing.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio/pci: Lock external INTx masking ops
Mask operations through config space changes to DisINTx may race INTx
configuration changes via ioctl. Create wrappers that add locking for
paths outside of the core interrupt code.
In particular, irq_type is updated holding igate, therefore testing
is_intx() requires holding igate. For example clearing DisINTx from
config space can otherwise race changes of the interrupt configuration.
This aligns interfaces which may trigger the INTx eventfd into two
camps, one side serialized by igate and the other only enabled while
INTx is configured. A subsequent patch introduces synchronization for
the latter flows.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wireguard: netlink: access device through ctx instead of peer
The previous commit fixed a bug that led to a NULL peer->device being
dereferenced. It's actually easier and faster performance-wise to
instead get the device from ctx->wg. This semantically makes more sense
too, since ctx->wg->peer_allowedips.seq is compared with
ctx->allowedips_seq, basing them both in ctx. This also acts as a
defence in depth provision against freed peers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dma: fix call order in dmam_free_coherent
dmam_free_coherent() frees a DMA allocation, which makes the
freed vaddr available for reuse, then calls devres_destroy()
to remove and free the data structure used to track the DMA
allocation. Between the two calls, it is possible for a
concurrent task to make an allocation with the same vaddr
and add it to the devres list.
If this happens, there will be two entries in the devres list
with the same vaddr and devres_destroy() can free the wrong
entry, triggering the WARN_ON() in dmam_match.
Fix by destroying the devres entry before freeing the DMA
allocation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Allow delete from sockmap/sockhash only if update is allowed
We have seen an influx of syzkaller reports where a BPF program attached to
a tracepoint triggers a locking rule violation by performing a map_delete
on a sockmap/sockhash.
We don't intend to support this artificial use scenario. Extend the
existing verifier allowed-program-type check for updating sockmap/sockhash
to also cover deleting from a map.
From now on only BPF programs which were previously allowed to update
sockmap/sockhash can delete from these map types.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: prevent UAF in ip6_send_skb()
syzbot reported an UAF in ip6_send_skb() [1]
After ip6_local_out() has returned, we no longer can safely
dereference rt, unless we hold rcu_read_lock().
A similar issue has been fixed in commit
a688caa34beb ("ipv6: take rcu lock in rawv6_send_hdrinc()")
Another potential issue in ip6_finish_output2() is handled in a
separate patch.

Summary
In the Linux kernel, the following vulnerability has been resolved:
block, bfq: fix possible UAF for bfqq->bic with merge chain
1) initial state, three tasks:
Process 1 Process 2 Process 3
(BIC1) (BIC2) (BIC3)
| Λ | Λ | Λ
| | | | | |
V | V | V |
bfqq1 bfqq2 bfqq3
process ref: 1 1 1
2) bfqq1 merged to bfqq2:
Process 1 Process 2 Process 3
(BIC1) (BIC2) (BIC3)
| | | Λ
\--------------\| | |
V V |
bfqq1--------->bfqq2 bfqq3
process ref: 0 2 1
3) bfqq2 merged to bfqq3:
Process 1 Process 2 Process 3
(BIC1) (BIC2) (BIC3)
here -> Λ | |
\--------------\ \-------------\|
V V
bfqq1--------->bfqq2---------->bfqq3
process ref: 0 1 3
In this case, IO from Process 1 will get bfqq2 from BIC1 first, and then
get bfqq3 through merge chain, and finially handle IO by bfqq3.
Howerver, current code will think bfqq2 is owned by BIC1, like initial
state, and set bfqq2->bic to BIC1.
bfq_insert_request
-> by Process 1
bfqq = bfq_init_rq(rq)
bfqq = bfq_get_bfqq_handle_split
bfqq = bic_to_bfqq
-> get bfqq2 from BIC1
bfqq->ref++
rq->elv.priv[0] = bic
rq->elv.priv[1] = bfqq
if (bfqq_process_refs(bfqq) == 1)
bfqq->bic = bic
-> record BIC1 to bfqq2
__bfq_insert_request
new_bfqq = bfq_setup_cooperator
-> get bfqq3 from bfqq2->new_bfqq
bfqq_request_freed(bfqq)
new_bfqq->ref++
rq->elv.priv[1] = new_bfqq
-> handle IO by bfqq3
Fix the problem by checking bfqq is from merge chain fist. And this
might fix a following problem reported by our syzkaller(unreproducible):

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mm: Disallow vsyscall page read for copy_from_kernel_nofault()
When trying to use copy_from_kernel_nofault() to read vsyscall page
through a bpf program, the following oops was reported:
BUG: unable to handle page fault for address: ffffffffff600000
#PF: supervisor read access in kernel mode

---[ end trace 0000000000000000 ]---
The oops is triggered when:
1) A bpf program uses bpf_probe_read_kernel() to read from the vsyscall
page and invokes copy_from_kernel_nofault() which in turn calls
__get_user_asm().
2) Because the vsyscall page address is not readable from kernel space,
a page fault exception is triggered accordingly.
3) handle_page_fault() considers the vsyscall page address as a user
space address instead of a kernel space address. This results in the
fix-up setup by bpf not being applied and a page_fault_oops() is invoked
due to SMAP.
Considering handle_page_fault() has already considered the vsyscall page
address as a userspace address, fix the problem by disallowing vsyscall
page read for copy_from_kernel_nofault().

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: call cache_put if xdr_reserve_space returns NULL
If not enough buffer space available, but idmap_lookup has triggered
lookup_fn which calls cache_get and returns successfully. Then we
missed to call cache_put here which pairs with cache_get.

CWE
- CWE-787 - Out-of-bounds Write
Summary
Issue summary: Use of the low-level GF(2^m) elliptic curve APIs with untrusted
explicit values for the field polynomial can lead to out-of-bounds memory reads
or writes.
Impact summary: Out of bound memory writes can lead to an application crash or
even a possibility of a remote code execution, however, in all the protocols
involving Elliptic Curve Cryptography that we're aware of, either only "named
curves" are supported, or, if explicit curve parameters are supported, they
specify an X9.62 encoding of binary (GF(2^m)) curves that can't represent
problematic input values. Thus the likelihood of existence of a vulnerable
application is low.
In particular, the X9.62 encoding is used for ECC keys in X.509 certificates,
so problematic inputs cannot occur in the context of processing X.509
certificates. Any problematic use-cases would have to be using an "exotic"
curve encoding.
The affected APIs include: EC_GROUP_new_curve_GF2m(), EC_GROUP_new_from_params(),
and various supporting BN_GF2m_*() functions.
Applications working with "exotic" explicit binary (GF(2^m)) curve parameters,
that make it possible to represent invalid field polynomials with a zero
constant term, via the above or similar APIs, may terminate abruptly as a
result of reading or writing outside of array bounds. Remote code execution
cannot easily be ruled out.
The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vt: fix unicode buffer corruption when deleting characters
This is the same issue that was fixed for the VGA text buffer in commit
39cdb68c64d8 ("vt: fix memory overlapping when deleting chars in the
buffer"). The cure is also the same i.e. replace memcpy() with memmove()
due to the overlaping buffers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: properly terminate timers for kernel sockets
We had various syzbot reports about tcp timers firing after
the corresponding netns has been dismantled.
Fortunately Josef Bacik could trigger the issue more often,
and could test a patch I wrote two years ago.
When TCP sockets are closed, we call inet_csk_clear_xmit_timers()
to 'stop' the timers.
inet_csk_clear_xmit_timers() can be called from any context,
including when socket lock is held.
This is the reason it uses sk_stop_timer(), aka del_timer().
This means that ongoing timers might finish much later.
For user sockets, this is fine because each running timer
holds a reference on the socket, and the user socket holds
a reference on the netns.
For kernel sockets, we risk that the netns is freed before
timer can complete, because kernel sockets do not hold
reference on the netns.
This patch adds inet_csk_clear_xmit_timers_sync() function
that using sk_stop_timer_sync() to make sure all timers
are terminated before the kernel socket is released.
Modules using kernel sockets close them in their netns exit()
handler.
Also add sock_not_owned_by_me() helper to get LOCKDEP
support : inet_csk_clear_xmit_timers_sync() must not be called
while socket lock is held.
It is very possible we can revert in the future commit
3a58f13a881e ("net: rds: acquire refcount on TCP sockets")
which attempted to solve the issue in rds only.
(net/smc/af_smc.c and net/mptcp/subflow.c have similar code)
We probably can remove the check_net() tests from
tcp_out_of_resources() and __tcp_close() in the future.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mm/pat: fix VM_PAT handling in COW mappings
PAT handling won't do the right thing in COW mappings: the first PTE (or,
in fact, all PTEs) can be replaced during write faults to point at anon
folios. Reliably recovering the correct PFN and cachemode using
follow_phys() from PTEs will not work in COW mappings.
Using follow_phys(), we might just get the address+protection of the anon
folio (which is very wrong), or fail on swap/nonswap entries, failing
follow_phys() and triggering a WARN_ON_ONCE() in untrack_pfn() and
track_pfn_copy(), not properly calling free_pfn_range().
In free_pfn_range(), we either wouldn't call memtype_free() or would call
it with the wrong range, possibly leaking memory.
To fix that, let's update follow_phys() to refuse returning anon folios,
and fallback to using the stored PFN inside vma->vm_pgoff for COW mappings
if we run into that.
We will now properly handle untrack_pfn() with COW mappings, where we
don't need the cachemode. We'll have to fail fork()->track_pfn_copy() if
the first page was replaced by an anon folio, though: we'd have to store
the cachemode in the VMA to make this work, likely growing the VMA size.
For now, lets keep it simple and let track_pfn_copy() just fail in that
case: it would have failed in the past with swap/nonswap entries already,
and it would have done the wrong thing with anon folios.
Simple reproducer to trigger the WARN_ON_ONCE() in untrack_pfn():

Reliably recovering the correct PFN and cachemode using\nfollow_phys() from PTEs will not work in COW mappings.\n\nUsing follow_phys(), we might just get the address+protection of the anon\nfolio (which is very wrong), or fail on swap/nonswap entries, failing\nfollow_phys() and triggering a WARN_ON_ONCE() in untrack_pfn() and\ntrack_pfn_copy(), not properly calling free_pfn_range().\n\nIn free_pfn_range(), we either wouldn\u0027t call memtype_free() or would call\nit with the wrong range, possibly leaking memory.\n\nTo fix that, let\u0027s update follow_phys() to refuse returning anon folios,\nand fallback to using the stored PFN inside vma-\u003evm_pgoff for COW mappings\nif we run into that.\n\nWe will now properly handle untrack_pfn() with COW mappings, where we\ndon\u0027t need the cachemode.

Summary
In the Linux kernel, the following vulnerability has been resolved:
erspan: make sure erspan_base_hdr is present in skb->head
syzbot reported a problem in ip6erspan_rcv() [1]
Issue is that ip6erspan_rcv() (and erspan_rcv()) no longer make
sure erspan_base_hdr is present in skb linear part (skb->head)
before getting @ver field from it.
Add the missing pskb_may_pull() calls.
v2: Reload iph pointer in erspan_rcv() after pskb_may_pull()
because skb->head might have changed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/exynos: hdmi: report safe 640x480 mode as a fallback when no EDID found
When reading EDID fails and driver reports no modes available, the DRM
core adds an artificial 1024x786 mode to the connector. Unfortunately
some variants of the Exynos HDMI (like the one in Exynos4 SoCs) are not
able to drive such mode, so report a safe 640x480 mode instead of nothing
in case of the EDID reading failure.
This fixes the following issue observed on Trats2 board since commit
13d5b040363c ("drm/exynos: do not return negative values from .get_modes()"):
[drm] Exynos DRM: using 11c00000.fimd device for DMA mapping operations

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/dpaa2: Avoid explicit cpumask var allocation on stack
For CONFIG_CPUMASK_OFFSTACK=y kernel, explicit allocation of cpumask
variable on stack is not recommended since it can cause potential stack
overflow.
Instead, kernel code should always use *cpumask_var API(s) to allocate
cpumask var in config-neutral way, leaving allocation strategy to
CONFIG_CPUMASK_OFFSTACK.
Use *cpumask_var API(s) to address it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: nci: Fix uninit-value in nci_dev_up and nci_ntf_packet
syzbot reported the following uninit-value access issue [1][2]:
nci_rx_work() parses and processes received packet. When the payload
length is zero, each message type handler reads uninitialized payload
and KMSAN detects this issue. The receipt of a packet with a zero-size
payload is considered unexpected, and therefore, such packets should be
silently discarded.
This patch resolved this issue by checking payload size before calling
each message type handler codes.

=====================================================
If the packet type ID field in the Ethernet header is either ETH_P_PRP or
ETH_P_HSR, but it is not followed by an HSR tag, hsr_get_skb_sequence_nr()
reads an invalid value as a sequence number. This causes the above issue.
This patch fixes the issue by returning NULL if the Ethernet header is not
followed by an HSR tag.

Summary
In the Linux kernel, the following vulnerability has been resolved:
kprobes: Fix possible use-after-free issue on kprobe registration
When unloading a module, its state is changing MODULE_STATE_LIVE ->
MODULE_STATE_GOING -> MODULE_STATE_UNFORMED. Each change will take
a time. `is_module_text_address()` and `__module_text_address()`
works with MODULE_STATE_LIVE and MODULE_STATE_GOING.
If we use `is_module_text_address()` and `__module_text_address()`
separately, there is a chance that the first one is succeeded but the
next one is failed because module->state becomes MODULE_STATE_UNFORMED
between those operations.
In `check_kprobe_address_safe()`, if the second `__module_text_address()`
is failed, that is ignored because it expected a kernel_text address.
But it may have failed simply because module->state has been changed
to MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modify
non-exist module text address (use-after-free).
To fix this problem, we should not use separated `is_module_text_address()`
and `__module_text_address()`, but use only `__module_text_address()`
once and do `try_module_get(module)` which is only available with
MODULE_STATE_LIVE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: atomisp: ssh_css: Fix a null-pointer dereference in load_video_binaries
The allocation failure of mycs->yuv_scaler_binary in load_video_binaries()
is followed with a dereference of mycs->yuv_scaler_binary after the
following call chain:
sh_css_pipe_load_binaries()
|-> load_video_binaries(mycs->yuv_scaler_binary == NULL)
|
|-> sh_css_pipe_unload_binaries()
|-> unload_video_binaries()
In unload_video_binaries(), it calls to ia_css_binary_unload with argument
&pipe->pipe_settings.video.yuv_scaler_binary[i], which refers to the
same memory slot as mycs->yuv_scaler_binary. Thus, a null-pointer
dereference is triggered.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: nexthop: Initialize all fields in dumped nexthops
struct nexthop_grp contains two reserved fields that are not initialized by
nla_put_nh_group(), and carry garbage. This can be observed e.g. with
strace (edited for clarity):
# ip nexthop add id 1 dev lo
# ip nexthop add id 101 group 1
# strace -e recvmsg ip nexthop get id 101
...
recvmsg(... [{nla_len=12, nla_type=NHA_GROUP},
[{id=1, weight=0, resvd1=0x69, resvd2=0x67}]] ...) = 52
The fields are reserved and therefore not currently used. But as they are, they
leak kernel memory, and the fact they are not just zero complicates repurposing
of the fields for new ends. Initialize the full structure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mtrr: Check if fixed MTRRs exist before saving them
MTRRs have an obsolete fixed variant for fine grained caching control
of the 640K-1MB region that uses separate MSRs. This fixed variant has
a separate capability bit in the MTRR capability MSR.
So far all x86 CPUs which support MTRR have this separate bit set, so it
went unnoticed that mtrr_save_state() does not check the capability bit
before accessing the fixed MTRR MSRs.
Though on a CPU that does not support the fixed MTRR capability this
results in a #GP. The #GP itself is harmless because the RDMSR fault is
handled gracefully, but results in a WARN_ON().
Add the missing capability check to prevent this.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: seeq: Fix use after free vulnerability in ether3 Driver Due to Race Condition
In the ether3_probe function, a timer is initialized with a callback
function ether3_ledoff, bound to &prev(dev)->timer. Once the timer is
started, there is a risk of a race condition if the module or device
is removed, triggering the ether3_remove function to perform cleanup.
The sequence of operations that may lead to a UAF bug is as follows:
CPU0 CPU1
| ether3_ledoff
ether3_remove |
free_netdev(dev); |
put_devic |
kfree(dev); |
| ether3_outw(priv(dev)->regs.config2 |= CFG2_CTRLO, REG_CONFIG2);
| // use dev
Fix it by ensuring that the timer is canceled before proceeding with
the cleanup in ether3_remove.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio/pci: Disable auto-enable of exclusive INTx IRQ
Currently for devices requiring masking at the irqchip for INTx, ie.
devices without DisINTx support, the IRQ is enabled in request_irq()
and subsequently disabled as necessary to align with the masked status
flag. This presents a window where the interrupt could fire between
these events, resulting in the IRQ incrementing the disable depth twice.
This would be unrecoverable for a user since the masked flag prevents
nested enables through vfio.
Instead, invert the logic using IRQF_NO_AUTOEN such that exclusive INTx
is never auto-enabled, then unmask as required.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/vboxvideo: Replace fake VLA at end of vbva_mouse_pointer_shape with real VLA
Replace the fake VLA at end of the vbva_mouse_pointer_shape shape with
a real VLA to fix a "memcpy: detected field-spanning write error" warning:
[ 13.319813] memcpy: detected field-spanning write (size 16896) of single field "p->data" at drivers/gpu/drm/vboxvideo/hgsmi_base.c:154 (size 4)
[ 13.319841] WARNING: CPU: 0 PID: 1105 at drivers/gpu/drm/vboxvideo/hgsmi_base.c:154 hgsmi_update_pointer_shape+0x192/0x1c0 [vboxvideo]
[ 13.320038] Call Trace:
[ 13.320173] hgsmi_update_pointer_shape [vboxvideo]
[ 13.320184] vbox_cursor_atomic_update [vboxvideo]
Note as mentioned in the added comment it seems the original length
calculation for the allocated and send hgsmi buffer is 4 bytes too large.
Changing this is not the goal of this patch, so this behavior is kept.

Summary
In the Linux kernel, the following vulnerability has been resolved:
padata: Fix possible divide-by-0 panic in padata_mt_helper()
We are hit with a not easily reproducible divide-by-0 panic in padata.c at
bootup time.
[ 10.017908] Oops: divide error: 0000 1 PREEMPT SMP NOPTI

Looking at the padata_mt_helper() function, the only way a divide-by-0
panic can happen is when ps->chunk_size is 0. The way that chunk_size is
initialized in padata_do_multithreaded(), chunk_size can be 0 when the
min_chunk in the passed-in padata_mt_job structure is 0.
Fix this divide-by-0 panic by making sure that chunk_size will be at least
1 no matter what the input parameters are.

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-cgroup: Fix UAF in blkcg_unpin_online()
blkcg_unpin_online() walks up the blkcg hierarchy putting the online pin. To
walk up, it uses blkcg_parent(blkcg) but it was calling that after
blkcg_destroy_blkgs(blkcg) which could free the blkcg, leading to the
following UAF:
==================================================================
BUG: KASAN: slab-use-after-free in blkcg_unpin_online+0x15a/0x270

Note that the UAF is not easy to trigger as the free path is indirected
behind a couple RCU grace periods and a work item execution. I could only
trigger it with artifical msleep() injected in blkcg_unpin_online().
Fix it by reading the parent pointer before destroying the blkcg's blkg's.

The Linux NFS client does not handle NFS?ERR_INVAL, even though all
NFS specifications permit servers to return that status code for a
READ.
Instead of NFS?ERR_INVAL, have out-of-range READ requests succeed
and return a short result. Set the EOF flag in the result to prevent
the client from retrying the READ request. This behavior appears to
be consistent with Solaris NFS servers.
Note that NFSv3 and NFSv4 use u64 offset values on the wire. These
must be converted to loff_t internally before use -- an implicit
type cast is not adequate for this purpose. Otherwise VFS checks
against sb->s_maxbytes do not work properly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: Fix null-ptr-deref in reuseport_add_sock().
syzbot reported a null-ptr-deref while accessing sk2->sk_reuseport_cb in
reuseport_add_sock(). [0]
The repro first creates a listener with SO_REUSEPORT. Then, it creates
another listener on the same port and concurrently closes the first
listener.
The second listen() calls reuseport_add_sock() with the first listener as
sk2, where sk2->sk_reuseport_cb is not expected to be cleared concurrently,
but the close() does clear it by reuseport_detach_sock().
The problem is SCTP does not properly synchronise reuseport_alloc(),
reuseport_add_sock(), and reuseport_detach_sock().
The caller of reuseport_alloc() and reuseport_{add,detach}_sock() must
provide synchronisation for sockets that are classified into the same
reuseport group.
Otherwise, such sockets form multiple identical reuseport groups, and
all groups except one would be silently dead.
1. Two sockets call listen() concurrently
2. No socket in the same group found in sctp_ep_hashtable[]
3. Two sockets call reuseport_alloc() and form two reuseport groups
4. Only one group hit first in __sctp_rcv_lookup_endpoint() receives
incoming packets
Also, the reported null-ptr-deref could occur.
TCP/UDP guarantees that would not happen by holding the hash bucket lock.
Let's apply the locking strategy to __sctp_hash_endpoint() and

[0]\n\nThe repro first creates a listener with SO_REUSEPORT. Then, it creates\nanother listener on the same port and concurrently closes the first\nlistener.\n\nThe second listen() calls reuseport_add_sock() with the first listener as\nsk2, where sk2-\u003esk_reuseport_cb is not expected to be cleared concurrently,\nbut the close() does clear it by reuseport_detach_sock().\n\nThe problem is SCTP does not properly synchronise reuseport_alloc(),\nreuseport_add_sock(), and reuseport_detach_sock().\n\nThe caller of reuseport_alloc() and reuseport_{add,detach}_sock() must\nprovide synchronisation for sockets that are classified into the same\nreuseport group.\n\nOtherwise, such sockets form multiple identical reuseport groups, and\nall groups except one would be silently dead.\n\n 1. Two sockets call listen() concurrently\n 2. No socket in the same group found in sctp_ep_hashtable[]\n 3. Two sockets call reuseport_alloc() and form two reuseport groups\n 4. Only one group hit first in __sctp_rcv_lookup_endpoint() receives\n incoming packets\n\nAlso, the reported null-ptr-deref could occur.\n\nTCP/UDP guarantees that would not happen by holding the hash bucket lock.\n\nLet\u0027s apply the locking strategy to __sctp_hash_endpoint() and\n__sctp_unhash_endpoint().\n\n[0]:\nOops: general protection fault, probably for non-canonical address 0xdffffc0000000002: 0000 [#1] PREEMPT SMP KASAN PTI\nKASAN: null-ptr-deref in range [0x0000000000000010-0x0000000000000017]\nCPU: 1 UID: 0 PID: 10230 Comm: syz-executor119 Not tainted 6.10.0-syzkaller-12585-g301927d2d2eb #0\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 06/27/2024\nRIP: 0010:reuseport_add_sock+0x27e/0x5e0 net/core/sock_reuseport.c:350\nCode: 00 0f b7 5d 00 bf 01 00 00 00 89 de e8 1b a4 ff f7 83 fb 01 0f 85 a3 01 00 00 e8 6d a0 ff f7 49 8d 7e 12 48 89 f8 48 c1 e8 03 \u003c42\u003e 0f b6 04 28 84 c0 0f 85 4b 02 00 00 41 0f b7 5e 12 49 8d 7e 14\nRSP: 0018:ffffc9000b947c98 EFLAGS: 00010202\nRAX: 0000000000000002 RBX: ffff8880252ddf98 RCX: ffff888079478000\nRDX: 0000000000000000 RSI: 0000000000000001 RDI: 0000000000000012\nRBP: 0000000000000001 R08: ffffffff8993e18d R09: 1ffffffff1fef385\nR10: dffffc0000000000 R11: fffffbfff1fef386 R12: ffff8880252ddac0\nR13: dffffc0000000000 R14: 0000000000000000 R15: 0000000000000000\nFS: 00007f24e45b96c0(0000) GS:ffff8880b9300000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 00007ffcced5f7b8 CR3: 00000000241be000 CR4: 00000000003506f0\nDR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\nCall Trace:\n \u003cTASK\u003e\n __sctp_hash_endpoint net/sctp/input.c:762 [inline]\n sctp_hash_endpoint+0x52a/0x600 net/sctp/input.c:790\n sctp_listen_start net/sctp/socket.c:8570 [inline]\n sctp_inet_listen+0x767/0xa20 net/sctp/socket.c:8625\n __sys_listen_socket net/socket.c:1883 [inline]\n __sys_listen+0x1b7/0x230 net/socket.c:1894\n __do_sys_listen net/socket.c:1902 [inline]\n __se_sys_listen net/socket.c:1900 [inline]\n __x64_sys_listen+0x5a/0x70 net/socket.c:1900\n do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n do_syscall_64+0xf3/0x230 arch/x86/entry/common.c:83\n entry_SYSCALL_64_after_hwframe+0x77/0x7f\nRIP: 0033:0x7f24e46039b9\nCode: 28 00 00 00 75 05 48 83 c4 28 c3 e8 91 1a 00 00 90 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 \u003c48\u003e 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b0 ff ff ff f7 d8 64 89 01 48\nRSP: 002b:00007f24e45b9228 EFLAGS: 00000246 ORIG_RAX: 0000000000000032\nRAX: ffffffffffffffda RBX: 00007f24e468e428 RCX: 00007f24e46039b9\nRDX: 00007f24e46039b9 RSI: 0000000000000003 RDI: 0000000000000004\nRBP: 00007f24e468e420 R08: 00007f24e45b96c0 R09: 00007f24e45b96c0\nR10: 00007f24e45b96c0 R11: 0000000000000246 R12: 00007f24e468e42c\nR13:\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: Fix uninitialized value issue in from_kuid and from_kgid
ocfs2_setattr() uses attr->ia_mode, attr->ia_uid and attr->ia_gid in
a trace point even though ATTR_MODE, ATTR_UID and ATTR_GID aren't set.
Initialize all fields of newattrs to avoid uninitialized variables, by
checking if ATTR_MODE, ATTR_UID, ATTR_GID are initialized, otherwise 0.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dm: call the resume method on internal suspend
There is this reported crash when experimenting with the lvm2 testsuite.
The list corruption is caused by the fact that the postsuspend and resume
methods were not paired correctly; there were two consecutive calls to the
origin_postsuspend function. The second call attempts to remove the
"hash_list" entry from a list, while it was already removed by the first
call.
Fix __dm_internal_resume so that it calls the preresume and resume
methods of the table's targets.
If a preresume method of some target fails, we are in a tricky situation.
We can't return an error because dm_internal_resume isn't supposed to
return errors. We can't return success, because then the "resume" and
"postsuspend" methods would not be paired correctly. So, we set the
DMF_SUSPENDED flag and we fake normal suspend - it may confuse userspace
tools, but it won't cause a kernel crash.

The second call attempts to remove the\n\"hash_list\" entry from a list, while it was already removed by the first\ncall.\n\nFix __dm_internal_resume so that it calls the preresume and resume\nmethods of the table\u0027s targets.\n\nIf a preresume method of some target fails, we are in a tricky situation.\nWe can\u0027t return an error because dm_internal_resume isn\u0027t supposed to\nreturn errors. We can\u0027t return success, because then the \"resume\" and\n\"postsuspend\" methods would not be paired correctly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix infinite loop when replaying fast_commit
When doing fast_commit replay an infinite loop may occur due to an
uninitialized extent_status struct. ext4_ext_determine_insert_hole() does
not detect the replay and calls ext4_es_find_extent_range(), which will
return immediately without initializing the 'es' variable.
Because 'es' contains garbage, an integer overflow may happen causing an
infinite loop in this function, easily reproducible using fstest generic/039.
This commit fixes this issue by unconditionally initializing the structure
in function ext4_es_find_extent_range().
Thanks to Zhang Yi, for figuring out the real problem!

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: act_skbmod: prevent kernel-infoleak
syzbot found that tcf_skbmod_dump() was copying four bytes
from kernel stack to user space [1].
The issue here is that 'struct tc_skbmod' has a four bytes hole.
We need to clear the structure before filling fields.

[Analysis]
There are two paths (dbUnmount and jfs_ioc_trim) that generate race
condition when accessing bmap, which leads to the occurrence of uaf.
Use the lock s_umount to synchronize them, in order to avoid uaf caused
by race condition.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wireguard: receive: annotate data-race around receiving_counter.counter
Syzkaller with KCSAN identified a data-race issue when accessing
keypair->receiving_counter.counter. Use READ_ONCE() and WRITE_ONCE()
annotations to mark the data race as intentional.
BUG: KCSAN: data-race in wg_packet_decrypt_worker / wg_packet_rx_poll

Summary
In the Linux kernel, the following vulnerability has been resolved:
tpm: Clean up TPM space after command failure
tpm_dev_transmit prepares the TPM space before attempting command
transmission. However if the command fails no rollback of this
preparation is done. This can result in transient handles being leaked
if the device is subsequently closed with no further commands performed.
Fix this by flushing the space in the event of command transmission
failure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
posix-clock: posix-clock: Fix unbalanced locking in pc_clock_settime()
If get_clock_desc() succeeds, it calls fget() for the clockid's fd,
and get the clk->rwsem read lock, so the error path should release
the lock to make the lock balance and fput the clockid's fd to make
the refcount balance and release the fd related resource.
However the below commit left the error path locked behind resulting in
unbalanced locking. Check timespec64_valid_strict() before
get_clock_desc() to fix it, because the "ts" is not changed
after that.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: set sk_state back to CLOSED if autobind fails in sctp_listen_start
In sctp_listen_start() invoked by sctp_inet_listen(), it should set the
sk_state back to CLOSED if sctp_autobind() fails due to whatever reason.
Otherwise, next time when calling sctp_inet_listen(), if sctp_sk(sk)->reuse
is already set via setsockopt(SCTP_REUSE_PORT), sctp_sk(sk)->bind_hash will
be dereferenced as sk_state is LISTENING, which causes a crash as bind_hash
is NULL.
KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]

Summary
In the Linux kernel, the following vulnerability has been resolved:
exec: don't WARN for racy path_noexec check
Both i_mode and noexec checks wrapped in WARN_ON stem from an artifact
of the previous implementation. They used to legitimately check for the
condition, but that got moved up in two commits:
633fb6ac3980 ("exec: move S_ISREG() check earlier")
0fd338b2d2cd ("exec: move path_noexec() check earlier")
Instead of being removed said checks are WARN_ON'ed instead, which
has some debug value.
However, the spurious path_noexec check is racy, resulting in
unwarranted warnings should someone race with setting the noexec flag.
One can note there is more to perm-checking whether execve is allowed
and none of the conditions are guaranteed to still hold after they were
tested for.
Additionally this does not validate whether the code path did any perm
checking to begin with -- it will pass if the inode happens to be
regular.
Keep the redundant path_noexec() check even though it's mindless
nonsense checking for guarantee that isn't given so drop the WARN.
Reword the commentary and do small tidy ups while here.

Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: usb-storage: Prevent divide-by-0 error in isd200_ata_command
The isd200 sub-driver in usb-storage uses the HEADS and SECTORS values
in the ATA ID information to calculate cylinder and head values when
creating a CDB for READ or WRITE commands. The calculation involves
division and modulus operations, which will cause a crash if either of
these values is 0. While this never happens with a genuine device, it
could happen with a flawed or subversive emulation, as reported by the
syzbot fuzzer.
Protect against this possibility by refusing to bind to the device if
either the ATA_ID_HEADS or ATA_ID_SECTORS value in the device's ID
information is 0. This requires isd200_Initialization() to return a
negative error code when initialization fails; currently it always
returns 0 (even when there is an error).

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: br_netfilter: fix panic with metadata_dst skb
Fix a kernel panic in the br_netfilter module when sending untagged
traffic via a VxLAN device.
This happens during the check for fragmentation in br_nf_dev_queue_xmit.
It is dependent on:
1) the br_netfilter module being loaded;
2) net.bridge.bridge-nf-call-iptables set to 1;
3) a bridge with a VxLAN (single-vxlan-device) netdevice as a bridge port;
4) untagged frames with size higher than the VxLAN MTU forwarded/flooded
When forwarding the untagged packet to the VxLAN bridge port, before
the netfilter hooks are called, br_handle_egress_vlan_tunnel is called and
changes the skb_dst to the tunnel dst. The tunnel_dst is a metadata type
of dst, i.e., skb_valid_dst(skb) is false, and metadata->dst.dev is NULL.
Then in the br_netfilter hooks, in br_nf_dev_queue_xmit, there's a check
for frames that needs to be fragmented: frames with higher MTU than the
VxLAN device end up calling br_nf_ip_fragment, which in turns call
ip_skb_dst_mtu.
The ip_dst_mtu tries to use the skb_dst(skb) as if it was a valid dst
with valid dst->dev, thus the crash.
This case was never supported in the first place, so drop the packet
instead.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: br_netfilter: fix panic with metadata_dst skb\n\nFix a kernel panic in the br_netfilter module when sending untagged\ntraffic via a VxLAN device.\nThis happens during the check for fragmentation in br_nf_dev_queue_xmit.\n\nIt is dependent on:\n1) the br_netfilter module being loaded;\n2) net.bridge.bridge-nf-call-iptables set to 1;\n3) a bridge with a VxLAN (single-vxlan-device) netdevice as a bridge port;\n4) untagged frames with size higher than the VxLAN MTU forwarded/flooded\n\nWhen forwarding the untagged packet to the VxLAN bridge port, before\nthe netfilter hooks are called, br_handle_egress_vlan_tunnel is called and\nchanges the skb_dst to the tunnel dst. The tunnel_dst is a metadata type\nof dst, i.e., skb_valid_dst(skb) is false, and metadata-\u003edst.dev is NULL.\n\nThen in the br_netfilter hooks, in br_nf_dev_queue_xmit, there\u0027s a check\nfor frames that needs to be fragmented: frames with higher MTU than the\nVxLAN device end up calling br_nf_ip_fragment, which in turns call\nip_skb_dst_mtu.\n\nThe ip_dst_mtu tries to use the skb_dst(skb) as if it was a valid dst\nwith valid dst-\u003edev, thus the crash.\n\nThis case was never supported in the first place, so drop the packet\ninstead.\n\nPING 10.0.0.2 (10.0.0.2) from 0.0.0.0 h1-eth0: 2000(2028) bytes of data.\n[ 176.291791] Unable to handle kernel NULL pointer dereference at\nvirtual address 0000000000000110\n[ 176.292101] Mem abort info:\n[ 176.292184] ESR = 0x0000000096000004\n[ 176.292322] EC = 0x25: DABT (current EL), IL = 32 bits\n[ 176.292530] SET = 0, FnV = 0\n[ 176.292709] EA = 0, S1PTW = 0\n[ 176.292862] FSC = 0x04: level 0 translation fault\n[ 176.293013] Data abort info:\n[ 176.293104] ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000\n[ 176.293488] CM = 0, WnR = 0, TnD = 0, TagAccess = 0\n[ 176.293787] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0\n[ 176.293995] user pgtable: 4k pages, 48-bit VAs, pgdp=0000000043ef5000\n[ 176.294166] [0000000000000110] pgd=0000000000000000,\np4d=0000000000000000\n[ 176.294827] Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP\n[ 176.295252] Modules linked in: vxlan ip6_udp_tunnel udp_tunnel veth\nbr_netfilter bridge stp llc ipv6 crct10dif_ce\n[ 176.295923] CPU: 0 PID: 188 Comm: ping Not tainted\n6.8.0-rc3-g5b3fbd61b9d1 #2\n[ 176.296314] Hardware name: linux,dummy-virt (DT)\n[ 176.296535] pstate: 80000005 (Nzcv daif -PAN -UAO -TCO -DIT -SSBS\nBTYPE=--)\n[ 176.296808] pc : br_nf_dev_queue_xmit+0x390/0x4ec [br_netfilter]\n[ 176.297382] lr : br_nf_dev_queue_xmit+0x2ac/0x4ec [br_netfilter]\n[ 176.297636] sp : ffff800080003630\n[ 176.297743] x29: ffff800080003630 x28: 0000000000000008 x27:\nffff6828c49ad9f8\n[ 176.298093] x26: ffff6828c49ad000 x25: 0000000000000000 x24:\n00000000000003e8\n[ 176.298430] x23: 0000000000000000 x22: ffff6828c4960b40 x21:\nffff6828c3b16d28\n[ 176.298652] x20: ffff6828c3167048 x19: ffff6828c3b16d00 x18:\n0000000000000014\n[ 176.298926] x17: ffffb0476322f000 x16: ffffb7e164023730 x15:\n0000000095744632\n[ 176.299296] x14: ffff6828c3f1c880 x13: 0000000000000002 x12:\nffffb7e137926a70\n[ 176.299574] x11: 0000000000000001 x10: ffff6828c3f1c898 x9 :\n0000000000000000\n[ 176.300049] x8 : ffff6828c49bf070 x7 : 0008460f18d5f20e x6 :\nf20e0100bebafeca\n[ 176.300302] x5 : ffff6828c7f918fe x4 : ffff6828c49bf070 x3 :\n0000000000000000\n[ 176.300586] x2 : 0000000000000000 x1 : ffff6828c3c7ad00 x0 :\nffff6828c7f918f0\n[ 176.300889] Call trace:\n[ 176.301123] br_nf_dev_queue_xmit+0x390/0x4ec [br_netfilter]\n[ 176.301411] br_nf_post_routing+0x2a8/0x3e4 [br_netfilter]\n[ 176.301703] nf_hook_slow+0x48/0x124\n[ 176.302060] br_forward_finish+0xc8/0xe8 [bridge]\n[ 176.302371] br_nf_hook_thresh+0x124/0x134 [br_netfilter]\n[ 176.302605] br_nf_forward_finish+0x118/0x22c [br_netfilter]\n[ 176.302824] br_nf_forward_ip.part.0+0x264/0x290 [br_netfilter]\n[ 176.303136] br_nf_forward+0x2b8/0x4e0 [br_netfilter]\n[ 176.303359] nf_hook_slow+0x48/0x124\n[ 176.303\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: reject new basechain after table flag update
When dormant flag is toggled, hooks are disabled in the commit phase by
iterating over current chains in table (existing and new).
The following configuration allows for an inconsistent state:
add table x
add chain x y { type filter hook input priority 0; }
add table x { flags dormant; }
add chain x w { type filter hook input priority 1; }
which triggers the following warning when trying to unregister chain w
which is already unregistered.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: bnep: fix wild-memory-access in proto_unregister
There's issue as follows:
KASAN: maybe wild-memory-access in range [0xdead...108-0xdead...10f]
CPU: 3 UID: 0 PID: 2805 Comm: rmmod Tainted: G W
RIP: 0010:proto_unregister+0xee/0x400
Call Trace:
<TASK>
__do_sys_delete_module+0x318/0x580
do_syscall_64+0xc1/0x1d0
entry_SYSCALL_64_after_hwframe+0x77/0x7f
As bnep_init() ignore bnep_sock_init()'s return value, and bnep_sock_init()
will cleanup all resource. Then when remove bnep module will call
bnep_sock_cleanup() to cleanup sock's resource.
To solve above issue just return bnep_sock_init()'s return value in
bnep_exit().

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: make sure the first directory block is not a hole
The syzbot constructs a directory that has no dirblock but is non-inline,
i.e. the first directory block is a hole. And no errors are reported when
creating files in this directory in the following flow.
ext4_mknod
...
ext4_add_entry
// Read block 0
ext4_read_dirblock(dir, block, DIRENT)
bh = ext4_bread(NULL, inode, block, 0)
if (!bh && (type == INDEX || type == DIRENT_HTREE))
// The first directory block is a hole
// But type == DIRENT, so no error is reported.
After that, we get a directory block without '.' and '..' but with a valid
dentry. This may cause some code that relies on dot or dotdot (such as
make_indexed_dir()) to crash.
Therefore when ext4_read_dirblock() finds that the first directory block
is a hole report that the filesystem is corrupted and return an error to
avoid loading corrupted data from disk causing something bad.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix stackmap overflow check on 32-bit arches
The stackmap code relies on roundup_pow_of_two() to compute the number
of hash buckets, and contains an overflow check by checking if the
resulting value is 0. However, on 32-bit arches, the roundup code itself
can overflow by doing a 32-bit left-shift of an unsigned long value,
which is undefined behaviour, so it is not guaranteed to truncate
neatly. This was triggered by syzbot on the DEVMAP_HASH type, which
contains the same check, copied from the hashtab code.
The commit in the fixes tag actually attempted to fix this, but the fix
did not account for the UB, so the fix only works on CPUs where an
overflow does result in a neat truncation to zero, which is not
guaranteed. Checking the value before rounding does not have this
problem.

However, on 32-bit arches, the roundup code itself\ncan overflow by doing a 32-bit left-shift of an unsigned long value,\nwhich is undefined behaviour, so it is not guaranteed to truncate\nneatly. This was triggered by syzbot on the DEVMAP_HASH type, which\ncontains the same check, copied from the hashtab code.\n\nThe commit in the fixes tag actually attempted to fix this, but the fix\ndid not account for the UB, so the fix only works on CPUs where an\noverflow does result in a neat truncation to zero, which is not\nguaranteed. Checking the value before rounding does not have this\nproblem."

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/rds: fix possible cp null dereference
cp might be null, calling cp->cp_conn would produce null dereference
[Simon Horman adds:]
Analysis:
* cp is a parameter of __rds_rdma_map and is not reassigned.
* The following call-sites pass a NULL cp argument to __rds_rdma_map()
- rds_get_mr()
- rds_get_mr_for_dest
* Prior to the code above, the following assumes that cp may be NULL
(which is indicative, but could itself be unnecessary)
trans_private = rs->rs_transport->get_mr(
sg, nents, rs, &mr->r_key, cp ? cp->cp_conn : NULL,
args->vec.addr, args->vec.bytes,
need_odp ? ODP_ZEROBASED : ODP_NOT_NEEDED);
* The code modified by this patch is guarded by IS_ERR(trans_private),
where trans_private is assigned as per the previous point in this analysis.
The only implementation of get_mr that I could locate is rds_ib_get_mr()
which can return an ERR_PTR if the conn (4th) argument is NULL.
* ret is set to PTR_ERR(trans_private).
rds_ib_get_mr can return ERR_PTR(-ENODEV) if the conn (4th) argument is NULL.
Thus ret may be -ENODEV in which case the code in question will execute.
Conclusion:
* cp may be NULL at the point where this patch adds a check;
this patch does seem to address a possible bug

---[ end trace 0000000000000000 ]---
Its possible that two threads call tcp_v6_do_rcv()/sk_forward_alloc_add()
concurrently when sk->sk_state == TCP_LISTEN with sk->sk_lock unlocked,
which triggers a data-race around sk->sk_forward_alloc:
tcp_v6_rcv
tcp_v6_do_rcv
skb_clone_and_charge_r
sk_rmem_schedule
__sk_mem_schedule
sk_forward_alloc_add()
skb_set_owner_r
sk_mem_charge
sk_forward_alloc_add()
__kfree_skb
skb_release_all
skb_release_head_state
sock_rfree
sk_mem_uncharge
sk_forward_alloc_add()
sk_mem_reclaim
// set local var reclaimable
__sk_mem_reclaim
sk_forward_alloc_add()
In this syzkaller testcase, two threads call
tcp_v6_do_rcv() with skb->truesize=768, the sk_forward_alloc changes like
this:
(cpu 1) | (cpu 2) | sk_forward_alloc
... | ... | 0
__sk_mem_schedule() | | +4096 = 4096
| __sk_mem_schedule() | +4096 = 8192
sk_mem_charge() | | -768 = 7424
| sk_mem_charge() | -768 = 6656
... | ... |
sk_mem_uncharge() | | +768 = 7424
reclaimable=7424 | |
| sk_mem_uncharge() | +768 = 8192
| reclaimable=8192 |
__sk_mem_reclaim() | | -4096 = 4096
| __sk_mem_reclaim() | -8192 = -4096 != 0
The skb_clone_and_charge_r() should not be called in tcp_v6_do_rcv() when
sk->sk_state is TCP_LISTEN, it happens later in tcp_v6_syn_recv_sock().
Fix the same issue in dccp_v6_do_rcv().

- CWE-1325 - Improperly Controlled Sequential Memory Allocation
Summary
Issue summary: Some non-default TLS server configurations can cause unbounded
memory growth when processing TLSv1.3 sessions
Impact summary: An attacker may exploit certain server configurations to trigger
unbounded memory growth that would lead to a Denial of Service
This problem can occur in TLSv1.3 if the non-default SSL_OP_NO_TICKET option is
being used (but not if early_data support is also configured and the default
anti-replay protection is in use). In this case, under certain conditions, the
session cache can get into an incorrect state and it will fail to flush properly
as it fills. The session cache will continue to grow in an unbounded manner. A
malicious client could deliberately create the scenario for this failure to
force a Denial of Service. It may also happen by accident in normal operation.
This issue only affects TLS servers supporting TLSv1.3. It does not affect TLS
clients.
The FIPS modules in 3.2, 3.1 and 3.0 are not affected by this issue. OpenSSL
1.0.2 is also not affected by this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jffs2: prevent xattr node from overflowing the eraseblock
Add a check to make sure that the requested xattr node size is no larger
than the eraseblock minus the cleanmarker.
Unlike the usual inode nodes, the xattr nodes aren't split into parts
and spread across multiple eraseblocks, which means that a xattr node
must not occupy more than one eraseblock. If the requested xattr value is
too large, the xattr node can spill onto the next eraseblock, overwriting
the nodes and causing errors such as:
jffs2: argh. node added in wrong place at 0x0000b050(2)
jffs2: nextblock 0x0000a000, expected at 0000b00c
jffs2: error: (823) do_verify_xattr_datum: node CRC failed at 0x01e050,
read=0xfc892c93, calc=0x000000
jffs2: notice: (823) jffs2_get_inode_nodes: Node header CRC failed
at 0x01e00c. {848f,2fc4,0fef511f,59a3d171}
jffs2: Node at 0x0000000c with length 0x00001044 would run over the
end of the erase block
jffs2: Perhaps the file system was created with the wrong erase size?
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found
at 0x00000010: 0x1044 instead
This breaks the filesystem and can lead to KASAN crashes such as:
BUG: KASAN: slab-out-of-bounds in jffs2_sum_add_kvec+0x125e/0x15d0

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: lantiq_etop: fix memory disclosure
When applying padding, the buffer is not zeroed, which results in memory
disclosure. The mentioned data is observed on the wire. This patch uses
skb_put_padto() to pad Ethernet frames properly. The mentioned function
zeroes the expanded buffer.
In case the packet cannot be padded it is silently dropped. Statistics
are also not incremented. This driver does not support statistics in the
old 32-bit format or the new 64-bit format. These will be added in the
future. In its current form, the patch should be easily backported to
stable versions.
Ethernet MACs on Amazon-SE and Danube cannot do padding of the packets
in hardware, so software padding must be applied.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: core: Check for unset descriptor
Make sure the descriptor has been set before looking at maxpacket.
This fixes a null pointer panic in this case.
This may happen if the gadget doesn't properly set up the endpoint
for the current speed, or the gadget descriptors are malformed and
the descriptor for the speed/endpoint are not found.
No current gadget driver is known to have this problem, but this
may cause a hard-to-find bug during development of new gadgets.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PM / devfreq: Fix buffer overflow in trans_stat_show
Fix buffer overflow in trans_stat_show().
Convert simple snprintf to the more secure scnprintf with size of
PAGE_SIZE.
Add condition checking if we are exceeding PAGE_SIZE and exit early from
loop. Also add at the end a warning that we exceeded PAGE_SIZE and that
stats is disabled.
Return -EFBIG in the case where we don't have enough space to write the
full transition table.
Also document in the ABI that this function can return -EFBIG error.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mad: Improve handling of timed out WRs of mad agent
Current timeout handler of mad agent acquires/releases mad_agent_priv
lock for every timed out WRs. This causes heavy locking contention
when higher no. of WRs are to be handled inside timeout handler.
This leads to softlockup with below trace in some use cases where
rdma-cm path is used to establish connection between peer nodes
Trace:

Simplified timeout handler by creating local list of timed out WRs
and invoke send handler post creating the list. The new method acquires/
releases lock once to fetch the list and hence helps to reduce locking
contetiong when processing higher no. of WRs

Summary
In the Linux kernel, the following vulnerability has been resolved:
speakup: Fix sizeof() vs ARRAY_SIZE() bug
The "buf" pointer is an array of u16 values. This code should be
using ARRAY_SIZE() (which is 256) instead of sizeof() (which is 512),
otherwise it can the still got out of bounds.

CWE
- CWE-131 - Incorrect Calculation of Buffer Size
Summary
The Linux kernel NFSD implementation prior to versions 5.19.17 and 6.0.2 are vulnerable to buffer overflow. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send buffers of a remote procedure call (RPC) into a single array of pages. A client can force the send buffer to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC message with garbage data is still correctly formed according to the specification and is passed forward to handlers. Vulnerable code in NFSD is not expecting the oversized request and writes beyond the allocated buffer space. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: compress: don't allow unaligned truncation on released compress inode
f2fs image may be corrupted after below testcase:
- mkfs.f2fs -O extra_attr,compression -f /dev/vdb
- mount /dev/vdb /mnt/f2fs
- touch /mnt/f2fs/file
- f2fs_io setflags compression /mnt/f2fs/file
- dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=4
- f2fs_io release_cblocks /mnt/f2fs/file
- truncate -s 8192 /mnt/f2fs/file
- umount /mnt/f2fs
- fsck.f2fs /dev/vdb
[ASSERT] (fsck_chk_inode_blk:1256) --> ino: 0x5 has i_blocks: 0x00000002, but has 0x3 blocks
[FSCK] valid_block_count matching with CP [Fail] [0x4, 0x5]
[FSCK] other corrupted bugs [Fail]
The reason is: partial truncation assume compressed inode has reserved
blocks, after partial truncation, valid block count may change w/o
.i_blocks and .total_valid_block_count update, result in corruption.
This patch only allow cluster size aligned truncation on released
compress inode for fixing.

The reproducer invokes shutdown() before entering the listener status.
After commit 94062790aedb ("tcp: defer shutdown(SEND_SHUTDOWN) for
TCP_SYN_RECV sockets"), the above causes the child to reach the accept
syscall in FIN_WAIT1 status.
Eric noted we can relax the existing assertion in __inet_accept()

Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER
In create_pinctrl(), pinctrl_maps_mutex is acquired before calling
add_setting(). If add_setting() returns -EPROBE_DEFER, create_pinctrl()
calls pinctrl_free(). However, pinctrl_free() attempts to acquire
pinctrl_maps_mutex, which is already held by create_pinctrl(), leading to
a potential deadlock.
This patch resolves the issue by releasing pinctrl_maps_mutex before
calling pinctrl_free(), preventing the deadlock.
This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drop_monitor: replace spin_lock by raw_spin_lock
trace_drop_common() is called with preemption disabled, and it acquires
a spin_lock. This is problematic for RT kernels because spin_locks are
sleeping locks in this configuration, which causes the following splat:

trace_drop_common() also disables interrupts, but this is a minor issue
because we could easily replace it with a local_lock.
Replace the spin_lock with raw_spin_lock to avoid sleeping in atomic
context.

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_packet: fix vlan_get_protocol_dgram() vs MSG_PEEK
Blamed commit forgot MSG_PEEK case, allowing a crash [1] as found
by syzbot.
Rework vlan_get_protocol_dgram() to not touch skb at all,
so that it can be used from many cpus on the same skb.
Add a const qualifier to skb argument.

Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: core: remove unnecessary WARN_ON() in implement()
Syzkaller hit a warning [1] in a call to implement() when trying
to write a value into a field of smaller size in an output report.
Since implement() already has a warn message printed out with the
help of hid_warn() and value in question gets trimmed with:
...
value &= m;
...
WARN_ON may be considered superfluous. Remove it to suppress future
syzkaller triggers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
r8169: add tally counter fields added with RTL8125
RTL8125 added fields to the tally counter, what may result in the chip
dma'ing these new fields to unallocated memory. Therefore make sure
that the allocated memory area is big enough to hold all of the
tally counter values, even if we use only parts of it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xfrm: validate new SA's prefixlen using SA family when sel.family is unset
This expands the validation introduced in commit 07bf7908950a ("xfrm:
Validate address prefix lengths in the xfrm selector.")
syzbot created an SA with
usersa.sel.family = AF_UNSPEC
usersa.sel.prefixlen_s = 128
usersa.family = AF_INET
Because of the AF_UNSPEC selector, verify_newsa_info doesn't put
limits on prefixlen_{s,d}. But then copy_from_user_state sets
x->sel.family to usersa.family (AF_INET). Do the same conversion in
verify_newsa_info before validating prefixlen_{s,d}, since that's how
prefixlen is going to be used later on.

Summary
In the Linux kernel, the following vulnerability has been resolved:
VMCI: Fix memcpy() run-time warning in dg_dispatch_as_host()
Syzkaller hit 'WARNING in dg_dispatch_as_host' bug.
memcpy: detected field-spanning write (size 56) of single field "&dg_info->msg"
at drivers/misc/vmw_vmci/vmci_datagram.c:237 (size 24)
WARNING: CPU: 0 PID: 1555 at drivers/misc/vmw_vmci/vmci_datagram.c:237
dg_dispatch_as_host+0x88e/0xa60 drivers/misc/vmw_vmci/vmci_datagram.c:237
Some code commentry, based on my understanding:
544 #define VMCI_DG_SIZE(_dg) (VMCI_DG_HEADERSIZE + (size_t)(_dg)->payload_size)
/// This is 24 + payload_size
memcpy(&dg_info->msg, dg, dg_size);
Destination = dg_info->msg ---> this is a 24 byte
structure(struct vmci_datagram)
Source = dg --> this is a 24 byte structure (struct vmci_datagram)
Size = dg_size = 24 + payload_size
{payload_size = 56-24 =32} -- Syzkaller managed to set payload_size to 32.
35 struct delayed_datagram_info {
36 struct datagram_entry *entry;
37 struct work_struct work;
38 bool in_dg_host_queue;
39 /* msg and msg_payload must be together. */
40 struct vmci_datagram msg;
41 u8 msg_payload[];
42 };
So those extra bytes of payload are copied into msg_payload[], a run time
warning is seen while fuzzing with Syzkaller.
One possible way to fix the warning is to split the memcpy() into
two parts -- one -- direct assignment of msg and second taking care of payload.
Gustavo quoted:
"Under FORTIFY_SOURCE we should not copy data across multiple members
in a structure."

Summary
In the Linux kernel, the following vulnerability has been resolved:
hv_netvsc: Register VF in netvsc_probe if NET_DEVICE_REGISTER missed
If hv_netvsc driver is unloaded and reloaded, the NET_DEVICE_REGISTER
handler cannot perform VF register successfully as the register call
is received before netvsc_probe is finished. This is because we
register register_netdevice_notifier() very early( even before
vmbus_driver_register()).
To fix this, we try to register each such matching VF( if it is visible
as a netdevice) at the end of netvsc_probe.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp_bpf: fix return value of tcp_bpf_sendmsg()
When we cork messages in psock->cork, the last message triggers the
flushing will result in sending a sk_msg larger than the current
message size. In this case, in tcp_bpf_send_verdict(), 'copied' becomes
negative at least in the following case:
468 case __SK_DROP:
469 default:
470 sk_msg_free_partial(sk, msg, tosend);
471 sk_msg_apply_bytes(psock, tosend);
472 *copied -= (tosend + delta); // <==== HERE
473 return -EACCES;
Therefore, it could lead to the following BUG with a proper value of
'copied' (thanks to syzbot). We should not use negative 'copied' as a
return value here.

We should not use negative \u0027copied\u0027 as a\nreturn value here.\n\n ------------[ cut here ]------------\n kernel BUG at net/socket.c:733!\n Internal error: Oops - BUG: 00000000f2000800 [#1] PREEMPT SMP\n Modules linked in:\n CPU: 0 UID: 0 PID: 3265 Comm: syz-executor510 Not tainted 6.11.0-rc3-syzkaller-00060-gd07b43284ab3 #0\n Hardware name: linux,dummy-virt (DT)\n pstate: 61400009 (nZCv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--)\n pc : sock_sendmsg_nosec net/socket.c:733 [inline]\n pc : sock_sendmsg_nosec net/socket.c:728 [inline]\n pc : __sock_sendmsg+0x5c/0x60 net/socket.c:745\n lr : sock_sendmsg_nosec net/socket.c:730 [inline]\n lr : __sock_sendmsg+0x54/0x60 net/socket.c:745\n sp : ffff800088ea3b30\n x29: ffff800088ea3b30 x28: fbf00000062bc900 x27: 0000000000000000\n x26: ffff800088ea3bc0 x25: ffff800088ea3bc0 x24: 0000000000000000\n x23: f9f00000048dc000 x22: 0000000000000000 x21: ffff800088ea3d90\n x20: f9f00000048dc000 x19: ffff800088ea3d90 x18: 0000000000000001\n x17: 0000000000000000 x16: 0000000000000000 x15: 000000002002ffaf\n x14: 0000000000000000 x13: 0000000000000000 x12: 0000000000000000\n x11: 0000000000000000 x10: ffff8000815849c0 x9 : ffff8000815b49c0\n x8 : 0000000000000000 x7 : 000000000000003f x6 : 0000000000000000\n x5 : 00000000000007e0 x4 : fff07ffffd239000 x3 : fbf00000062bc900\n x2 : 0000000000000000 x1 : 0000000000000000 x0 : 00000000fffffdef\n Call trace:\n sock_sendmsg_nosec net/socket.c:733 [inline]\n __sock_sendmsg+0x5c/0x60 net/socket.c:745\n ____sys_sendmsg+0x274/0x2ac net/socket.c:2597\n ___sys_sendmsg+0xac/0x100 net/socket.c:2651\n __sys_sendmsg+0x84/0xe0 net/socket.c:2680\n __do_sys_sendmsg net/socket.c:2689 [inline]\n __se_sys_sendmsg net/socket.c:2687 [inline]\n __arm64_sys_sendmsg+0x24/0x30 net/socket.c:2687\n __invoke_syscall arch/arm64/kernel/syscall.c:35 [inline]\n invoke_syscall+0x48/0x110 arch/arm64/kernel/syscall.c:49\n el0_svc_common.constprop.0+0x40/0xe0 arch/arm64/kernel/syscall.c:132\n do_el0_svc+0x1c/0x28 arch/arm64/kernel/syscall.c:151\n el0_svc+0x34/0xec arch/arm64/kernel/entry-common.c:712\n el0t_64_sync_handler+0x100/0x12c arch/arm64/kernel/entry-common.c:730\n el0t_64_sync+0x19c/0x1a0 arch/arm64/kernel/entry.S:598\n Code: f9404463 d63f0060 3108441f 54fffe81 (d4210000)\n ---[ end trace 0000000000000000 ]---"
