Ensure nodev option on /var/tmp partition
mount-var-tmp-nodev · RHEL ≥ 8 · 1 impl
Description
The nodev mount option prevents device files from being interpreted on /var/tmp. Device files should only exist in /dev.
Rationale
Allowing device files on /var/tmp could allow an attacker to create special devices that access hardware directly.
