Severity Moderate
Affected Packages 20
CVEs 45
Info Packages References Vulnerabilities

An update for kernel is now available for AlmaLinux AlmaLinux Product Security has rated this update as having a security impact of Moderate. 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.

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

Security Fix(es):
