An update that solves 5 vulnerabilities and has one errata
is now available.

Description:

This update for the Linux Kernel 4.12.14-197_72 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-2020-27786: Fixed a potential user after free which could have led
to memory corruption or privilege escalation (bsc#1179616).
- 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).
