ALMA-09-026200 - AlmaLinux OS 9 must prevent files with the setuid and setgid bit set from being executed on the /boot/efi directory.
Information
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/efi" directory.See Also
