  <description>This update for the Linux Kernel 5.3.18-22 fixes several issues.

The following security issues were fixed:

- CVE-2020-29368: Fixed an issue in copy-on-write implementation which could have granted unintended write access because of a race condition in a THP mapcount check (bsc#1179664).
- Fixed an issue where NFS client filesystems got unmounted on fail-over (bsc#1182468). 
- CVE-2021-3347: Fixed a use-after-free in the PI futexes during fault handling, allowing local users to execute code in the kernel (bsc#1181553).
- CVE-2020-28374: Fixed insufficient identifier checking in the LIO SCSI target code which could have been used by remote attackers to read or write files via directory traversal in an XCOPY request (bsc#1178684).
- CVE-2021-0342: Fixed a potential memory corruption due to a use after free which could have led to local escalation of privilege with System execution privileges required (bsc#1180859).
