Fix Recommendation

Configure RHEL 10 to prevent files with the "setuid" and "setgid" bit set from being executed on file systems that contain user home directories.

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

Check Contents

Verify RHEL 10 is configured so that "/home" is mounted with the "nosuid" option with the following command:

Note: If a separate file system has not been created for the user home directories (user home directories are mounted under "/"), this is automatically a finding, as the "nosuid" option cannot be used on the "/" system.

$ mount | grep /home
/dev/mapper/luks-ca2261ed-7b00-4b7b-84cd-8cd6d8fa4b28 on /home type xfs (rw,nodev,nosuid,noexec,seclabel)

If the "/home" file system is mounted without the "nosuid" option, this is a finding.
