CVE-2023-28466 Open this link in a new tabHow to fix?
Upgrade RHEL:8 kernel-debug to version 0:4.18.0-477.15.1.el8_8 or higher.
This issue was patched in RHSA-2023:3847.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-debug package and not the kernel-debug 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).
