   An update that fixes three vulnerabilities is now available.

Description:

   This update for the Linux Kernel 4.12.14-150100_197_111 fixes several
   issues.

   The following security issues were fixed:

   - CVE-2022-20154: Fixed a use after free due to a race condition in
     lock_sock_nested of sock.c. This could lead to local escalation of
     privilege with System execution privileges needed (bsc#1200599).
   - CVE-2022-21499: Reinforced the kernel lockdown feature, until now it's
     been trivial to break out of it with kgdb or kdb (bsc#1199426).
   - CVE-2022-1729: Fixed a sys_perf_event_open() race condition against self
     (bsc#1199507).
