   An update that fixes three vulnerabilities is now available.


   This update for the Linux Kernel 5.3.18-24_46 fixes several issues.

   The following security issues were fixed:

   - CVE-2020-29373: Fixed an issue where kernel unsafely handles the root
     directory during path lookups, and thus a process inside a mount
     namespace can escape to unintended filesystem locations (bsc#1179779).
   - CVE-2020-29569: Fixed a use after free due to a logic error
   - CVE-2020-29368: Fixed an issue in copy-on-write implementation which
     could grant unintended write access because of a race condition in a THP
     mapcount check (bsc#1179664).
