Description:
This update for the Linux Kernel 5.3.18-22 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-2020-36158: Fixed a potential remote code execution in the Marvell mwifiex driver (bsc#1180562).
- CVE-2020-0465: Fixed multiple missing bounds checks in hid-multitouch.c that could have led to local privilege escalation (bnc#1180030).
- CVE-2020-0466: Fixed a use-after-free due to a logic error in do_epoll_ctl and ep_loop_check_proc of eventpoll.c (bnc#1180032.
- CVE-2020-29569: Fixed a use after free due to a logic error (bsc#1180008).
- CVE-2020-29660: Fixed a locking inconsistency in the tty subsystem that may have allowed a read-after-free attack against TIOCGSID (bsc#1179877).
- CVE-2020-29661: Fixed a locking issue in the tty subsystem that allowed a use-after-free attack against TIOCSPGRP (bsc#1179877).
- 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).
