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

This update for the Linux Kernel 5.3.18-150300_59_54 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)
