Information

AlmaLinux OS 9 must mount /tmp with the nodev option.

GROUP ID: V-269317
RULE ID: SV-269317r1050199

The "nodev" mount option causes the system to not interpret character or block special devices. Executing character or block special devices from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access.

The only legitimate location for device files is the "/dev" directory located on the root partition, with the exception of chroot jails if implemented.

Solution

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