An update is available for kernel.
This update affects Rocky Linux 8.
A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE list
The kernel packages contain the Linux kernel, the core of any Linux operating system.
