AlmaLinux OS 9 must prevent files with the setuid and setgid bit set from being executed on file systems that are used with removable media.

An XCCDF Rule

Description

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.
