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

How to fix?

Upgrade Oracle:9 perf to version 0:5.14.0-284.18.1.el9_2 or higher.
This issue was patched in ELSA-2023-3723.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Oracle. See How to fix? for Oracle:9 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).
