How to fix?

Upgrade RHEL:9 kernel-rt-debug-core to version 0:5.14.0-284.18.1.rt14.303.el9_2 or higher.
This issue was patched in RHSA-2023:3708.

NVD Description

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