Full takeover

What to do

Apply the pending AlmaLinux security updates for the affected packages, starting with kernel and glibc.

The Brief

AlmaLinux issued security updates for many packages, including kernel, glibc, mariadb, mysql, php and squid.
The LWN roundup is truncated, so the full package list and the vulnerabilities fixed are not visible in the sources.

Teams running AlmaLinux with the listed packages should apply the updates, since several are core components such as the kernel and glibc.
