To reach the vulnerability kernel configuration flag CONFIG_TLS  or CONFIG_XFRM_ESPINTCP  has to be configured, but the operation does not require any privilege.\n\nThere is a use-after-free bug of icsk_ulp_data  of a struct inet_connection_sock.\n\nWhen CONFIG_TLS  is enabled, user can install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is created from the listener, the context is inherited and vulnerable.\n\nThe setsockopt  TCP_ULP  operation does not require any privilege.\n\nWe recommend upgrading past commit  2c02d41d71f90a5168391b6a5f2954112ba2307c",

CVE-2023-23454 (GCVE-0-2023-23454)

Vulnerability from cvelistv5

Published

2023-01-12 00:00

Modified

2025-03-20 20:55

Severity ?

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

CWE

Summary

cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results).

CVE-2023-1281 (GCVE-0-2023-1281)

Vulnerability from cvelistv5

Published

2023-03-22 13:18

Modified

2025-03-05 19:22

Severity ?

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

CWE

CWE-416 - Use After Free

Summary

Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2.

CWE-416 - Use After Free

Summary

There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is created from the listener, the context is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c

CVE-2023-1872 (GCVE-0-2023-1872)

Vulnerability from cvelistv5

Published

2023-04-12 15:40

Modified

2025-02-13 16:39

Severity ?

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

CWE

CWE-416 - Use After Free

Summary

A use-after-free vulnerability in the Linux Kernel io_uring system can be exploited to achieve local privilege escalation. The io_file_get_fixed function lacks the presence of ctx->uring_lock which can lead to a Use-After-Free vulnerability due a race condition with fixed files getting unregistered. We recommend upgrading past commit da24142b1ef9fd5d36b76e36bab328a5b27523e8.
