How to fix?

Upgrade RHEL:8 kernel-doc to version 0:4.18.0-372.70.1.el8_6 or higher.
This issue was patched in RHSA-2023:4789.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-doc package and not the kernel-doc package as distributed by RHEL. See How to fix? for RHEL:8 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).
