Synopsis

Important: kernel security and bug fix update

Type/Severity

Security Advisory Important

Topic

An update for kernel is now available for Red Hat Enterprise Linux 8.8 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.

Description

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

Security Fix(es):
