Information

AlmaLinux OS 9 must prevent files with the setuid and setgid bit set from being executed on the /boot directory.

GROUP ID: V-269313
RULE ID: SV-269313r1050195

The "nosuid" mount option causes the system not to 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 "/boot" directory.
