  <description>This update for the Linux Kernel 5.3.18-150200_24_134 fixes several issues.

The following security issues were fixed:

- 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-2022-39189: Fixed a bug in the x86 KVM subsystem which allows unprivileged guest users to compromise the guest kernel because TLB flush operations are mishandled (bnc#1203066).
