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).
