Set nodev option for /tmp Partition (Scored)
The nodev mount option specifies that the filesystem cannot contain special devices.
Parameter:
[]
Technical Mechanism:
Since the /tmp filesystem is not intended to support devices, set this option to ensure that users cannot attempt to create block or character special devices in /tmp.
Fix:
Edit the /etc/fstab file and add nodev to the fourth field (mounting options). See the fstab(5) manual page for more information.
# mount -o remount,nodev /tmp
