=====================================================================

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.

The following packages have been upgraded to a later upstream version:
kernel (4.18.0).

Security Fix(es):

* A use-after-free in cls_route filter implementation may lead to privilege
escalation (CVE-2022-2588)

* Information leak in the IPv6 implementation (CVE-2021-45485)

* Information leak in the IPv4 implementation (CVE-2021-45486)

* Incomplete cleanup of multi-core shared buffers (aka SBDR)
(CVE-2022-21123)

* Incomplete cleanup of microarchitectural fill buffers (aka SBDS)
(CVE-2022-21125)

* Incomplete cleanup in specific special register write operations (aka
DRPW) (CVE-2022-21166)

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):

* DR, Ignore modify TTL if ConnectX-5 doesn't support it (BZ#2075549)

* execve exit tracepoint not called (BZ#2106663)

* Unable to boot RHEL-8.6 on Brazos max. config (Install is success)
(BZ#2107475)

* "vmcore failed, _exitcode:139" error observed while capturing vmcore
during fadump after memory remove. incomplete vmcore is captured.
(BZ#2107490)

* soft lockups under heavy I/O load to ahci connected SSDs (BZ#2110773)

* Allow substituting custom vmlinux.h for the build (BZ#2116407)

4. Solution:

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