Security update for the Linux Kernel (Live Patch 20 for SLE 15 SP2)

Notes

Title of the patch
Security update for the Linux Kernel (Live Patch 20 for SLE 15 SP2)
Description of the patch
This update for the Linux Kernel 5.3.18-24_86 fixes several issues. The following security issues were fixed: - CVE-2022-27666: Fixed a buffer overflow vulnerability in IPsec ESP transformation code. This flaw allowed a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation. (bnc#1197462) - CVE-2021-39698: Fixed a possible memory corruption due to a use after free in aio_poll_complete_work. This could lead to local escalation of privilege with no additional execution privileges needed. (bsc#1196956) - CVE-2022-22942: Fixed stale file descriptors on failed usercopy. (bsc#1195065)
