CVE-2023-28466  (opens in a new tab)
CWE-476  (opens in a new tab)

How to fix?

Upgrade SLES:15.2 kernel-docs to version 5.3.18-150200.24.148.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-docs package and not the kernel-docs package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference).
