An update that solves two vulnerabilities and has one
errata is now available.

Description:

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)
