Information

AlmaLinux OS 9 must mount /var/tmp with the nosuid option.

GROUP ID: V-269329
RULE ID: SV-269329r1050211

The "nosuid" mount option causes the system to not execute "setuid" and "setgid" files with owner privileges. This option must be used for mounting any file system not containing approved "setuid" and "setguid" files.

Executing files from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access.

Solution

Modify "/etc/fstab" to use the "nosuid" option on the "/var/tmp" directory.
