Expired pointer dereference in some Intel(R) Graphics Drivers before version 26.20.100.8141 may allow a privileged user to potentially enable a denial of service via local access.

This update for kernel-firmware fixes the following issues :

  - CVE-2020-12373: Fixed an expired pointer dereference may     lead to DOS (bsc#1181738).

  - CVE-2020-12364: Fixed a NULL pointer reference may lead     to DOS (bsc#1181736). 

  - CVE-2020-12362: Fixed an integer overflow which could     have led to privilege escalation (bsc#1181720).

  - CVE-2020-12363: Fixed an improper input validation which     may have led to DOS (bsc#1181735).

This update was imported from the SUSE:SLE-15-SP1:Update update project.

The SUSE Linux Enterprise 15 SP2 kernel RT was updated to receive various security and bugfixes.

CVE-2020-29368,CVE-2020-29374: 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#1179660, bsc#1179428).

The update package also includes non-security fixes. See advisory for details.
