Upgrade AlmaLinux:9 kernel-uki-virt to version 0:5.14.0-284.18.1.el9_2 or higher.

NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-uki-virt package and not the kernel-uki-virt package as distributed by AlmaLinux.
See How to fix? for AlmaLinux: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).
