Title of the patch
Security update for the Linux Kernel
Description of the patch
The SUSE Linux Enterprise 15 SP3 RT kernel was updated to receive various security bugfixes.
The following security bugs were fixed:
- CVE-2024-1086: Fixed a use-after-free vulnerability inside the nf_tables component that could have been exploited to achieve local privilege escalation (bsc#1219434).
- CVE-2023-51780: Fixed a use-after-free in do_vcc_ioctl in net/atm/ioctl.c, because of a vcc_recvmsg race condition (bsc#1218730).
- CVE-2023-46838: Fixed an issue with Xen netback processing of zero-length transmit fragment (bsc#1218836).
- CVE-2021-33631: Fixed an integer overflow in ext4_write_inline_data_end() (bsc#1219412).
- CVE-2023-6535: Fixed a NULL pointer dereference in nvmet_tcp_execute_request (bsc#1217988).
- CVE-2023-6536: Fixed a NULL pointer dereference in __nvmet_req_complete (bsc#1217989).
- CVE-2023-6356: Fixed a NULL pointer dereference in nvmet_tcp_build_pdu_iovec (bsc#1217987).
- CVE-2023-47233: Fixed a use-after-free in the device unplugging (disconnect the USB by hotplug) code inside the brcm80211 component (bsc#1216702).
- CVE-2023-51043: Fixed use-after-free during a race condition between a nonblocking atomic commit and a driver unload in drivers/gpu/drm/drm_atomic.c (bsc#1219120).
- CVE-2024-0775: Fixed use-after-free in __ext4_remount in fs/ext4/super.c that could allow a local user to cause an information leak problem while freeing the old quota file names before a potential failure (bsc#1219053).
- CVE-2024-0565: Fixed an out-of-bounds memory read flaw in receive_encrypted_standard in fs/smb/client/smb2ops.c (bsc#1218832).
- CVE-2023-6915: Fixed a NULL pointer dereference problem in ida_free in lib/idr.c (bsc#1218804).
- CVE-2023-6040: Fixed an out-of-bounds access vulnerability while creating a new netfilter table, lack of a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function (bsc#1218752).
- CVE-2023-51782: Fixed use-after-free in rose_ioctl in net/rose/af_rose.c because of a rose_accept race condition (bsc#1218757).
The following non-security bugs were fixed:
- Store the old kernel changelog entries in kernel-docs package (bsc#1218713).
- x86/entry/ia32: Ensure s32 is sign extended to s64 (bsc#1193285).

Summary
An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4 (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an attacker to achieve out-of-bounds access.

Summary
Transmit requests in Xen's virtual network protocol can consist of
multiple parts. While not really useful, except for the initial part
any of them may be of zero length, i.e. carry no data at all. Besides a
certain initial portion of the to be transferred data, these parts are
directly translated into what Linux calls SKB fragments. Such converted
request parts can, when for a particular SKB they are all of length
zero, lead to a de-reference of NULL in core networking code.

Summary
The brcm80211 component in the Linux kernel through 6.5.10 has a brcmf_cfg80211_detach use-after-free in the device unplugging (disconnect the USB by hotplug) code. For physically proximate attackers with local access, this "could be exploited in a real world scenario." This is related to brcmf_cfg80211_escan_timeout_worker in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c.

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 nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT.
We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.
