Vulnerability Discussion

The use of separate file systems for different paths can protect the system from failures resulting from a file system becoming full or failing.

Check

Verify that a separate file system/partition has been created for "/var/tmp".

Check that a file system/partition has been created for "/var/tmp" with the following command:

$ sudo grep /var/tmp /etc/fstab

UUID=c274f65f /var/tmp xfs noatime,nobarrier 1 2

If a separate entry for "/var/tmp" is not in use, this is a finding.

Fix

Migrate the "/var/tmp" path onto a separate file system.
