QID 751036: SUSE Enterprise Linux Security Update for the Linux Kernel (Live Patch 40 for SLE 12 SP3) (SUSE-SU-2021:2846-1)

This update for the linux kernel 4.4.180-94_147 fixes several issues.
The following security issues were fixed: - cve-2021-37576: on the powerpc platform kvm guest os users could cause host os memory corruption via rtas_args.nargs (bsc#1188838).
- cve-2021-28688: the fix for xsa-365 includes initialization of pointers such that subsequent cleanup code wouldn't use uninitialized or stale values.
This initialization went too far and may under certain conditions also overwrite pointers which are in need of cleaning up.
(bsc#1183646) - cve-2020-0429: fixed a potential local privilege escalation in l2tp_session_delete and related functions of l2tp_core.c (bsc#1176724).

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

Successful exploitation allows attacker to compromise the system.
