QID 174816: SUSE Enterprise Linux Security update for the Linux Kernel (Live Patch 10 for SLE 15 SP2) (SUSE-SU-2021:0869-1)

This update for the Linux Kernel 5.3.18-24_49 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).
- CVE-2020-29373: Fixed an issue where kernel unsafely handles the root
directory during path lookups, and thus a process inside a mount
namespace could escape to unintended filesystem locations (bsc#1179779).

Successful exploitation allows attacker to compromise the system.
