An update that solves two vulnerabilities can now be installed.

Description:

This update for the Linux Kernel 5.3.18-24_102 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)
