Cross-References: CVE-2020-36322 CVE-2021-29154
Affected Products:

______________________________________________________________________________
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:
o Fix a kernel warning during sysfs read (bsc#1186235)
o 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).
o 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)
