How to fix?

Upgrade Centos:8 kernel-zfcpdump-modules-extra to version 0:4.18.0-477.15.1.el8_8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-modules-extra package and not the kernel-zfcpdump-modules-extra package as distributed by Centos. See How to fix? for Centos: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).
