SUSE Security Update: Security update for the Linux Kernel (Live Patch 22 for
SLE 15)
______________________________________________________________________________
Announcement ID: SUSE-SU-2021:1728-1
Rating: important
References: #1178066 #1184710 #1184952
Cross-References: CVE-2020-0433 CVE-2020-36322 CVE-2021-29154
Affected Products:
SUSE Linux Enterprise Module for Live Patching 15
______________________________________________________________________________
An update that fixes three vulnerabilities is now available.
Description:
This update for the Linux Kernel 4.12.14-150_66 fixes several issues.
The following security issues were fixed:
o CVE-2020-36322: Fixed an issue inside the FUSE filesystem implementation
where fuse_do_getattr() calls make_bad_inode() in inappropriate situations,
could have caused 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-2020-0433: Fixed blk_mq_queue_tag_busy_iter of blk-mq-tag.c, where a
possible use after free due to improper locking could have happened. This
could have led to local escalation of privilege with no additional
execution privileges needed. User interaction is not needed for
exploitation (bnc#1178066).
o CVE-2021-29154: Fixed BPF JIT compilers that allowed to execute arbitrary
code within the kernel context (bsc#1184710)
Patch Instructions:
To install this SUSE Security Update use the SUSE recommended installation
methods like YaST online_update or "zypper patch".
Alternatively you can run the command listed for your product:
