Information

AlmaLinux OS 9 must mount /dev/shm with the nodev option.

GROUP ID: V-269314
RULE ID: SV-269314r1050196

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 "/dev/shm" file system.
