====================================================================
1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 8.4
Extended Update 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 CodeReady Linux Builder EUS (v. 8.4) - aarch64, ppc64le, x86_64
Red Hat Enterprise Linux BaseOS EUS (v.8.4) - aarch64, noarch, ppc64le, s390x, x86_64

3. Description:

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

Security Fix(es):

* kernel: Insufficient validation of user-supplied sizes for the MSG_CRYPTO
message type (CVE-2021-43267)

* kernel: timer tree corruption leads to missing wakeup and system freeze
(CVE-2021-20317)

* kernel: fuse: stall on CPU can occur because a retry loop continually
finds the same bad inode (CVE-2021-28950)

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.

Bug Fix(es):

* Fix repeated xhci wake after suspend due to uncleared internal wake state
(BZ#2003789)

* CephFS mount points return "permission denied" (BZ#2017099)

Enhancement(s):

* Update qla2xxx driver to latest upstream (BZ#2014150)

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.
