QID 750111: SUSE Enterprise Linux Security Update for the Linux Kernel (Live Patch 35 for SLE 12 SP3) (SUSE-SU-2021:1865-1)

This update for the linux kernel 4.4.180-94_130 fixes several issues.
the following security issues were fixed: - fix a kernel warning during sysfs read (bsc#1186235) - cve-2020-36322: an issue was discovered in the fuse filesystem implementation in the linux kernel aka cid-5d069dbe8aaf.
fuse_do_getattr() calls make_bad_inode() in inappropriate situations, causing a system crash.
Note: the original fix for this vulnerability was incomplete, and its incompleteness is tracked as cve-2021-28950 (bsc#1184952).
- cve-2021-29154: bpf jit compilers in the linux kernel have incorrect computation of branch displacements, allowing them to execute arbitrary code within the kernel context.
This affects arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c (bsc#1184710)

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.
