   An update that fixes three vulnerabilities is now available.

Description:

   This update for the Linux Kernel 5.3.18-150300_59_43 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)
