1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 8.6
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.8.6) - aarch64, ppc64le, x86_64
