1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 6
Extended Lifecycle Support.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Server (v. 6 ELS) - i386, noarch, s390x, x86_64
Red Hat Enterprise Linux Server Optional (v. 6 ELS) - i386, s390x, x86_64

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es):

* kernel: use after free in eventpoll.c may lead to escalation of privilege
(CVE-2020-0466)

* kernel: Use After Free in unix_gc() which could result in a local
privilege escalation (CVE-2021-0920)

* kernel: xfs: raw block device data leak in XFS_IOC_ALLOCSP IOCTL
(CVE-2021-4155)

* kernel: cgroups v1 release_agent feature may allow privilege escalation
(CVE-2022-0492)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

The system must be rebooted for this update to take effect.
