This update for the Linux Kernel 4.12.14-95_80 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).
