Security update for the Linux Kernel (Live Patch 4 for SLE 15 SP3)

Notes

Title of the patch
Security update for the Linux Kernel (Live Patch 4 for SLE 15 SP3)
Description of the patch
This update for the Linux Kernel 5.3.18-59_16 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)
