RHEL 10 must prevent special devices on nonroot local partitions.

Rule version RHEL-10-700200 · STIG v1 · 2026-09-17

Discussion

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.

Check

Verify RHEL 10 is configured so that all nonroot local partitions are mounted with the "nodev" option with the following command:

$ sudo mount | grep '^/dev\S* on /\S' | grep --invert-match 'nodev'

If any output is produced, this is a finding.

Fix

Configure RHEL 10 so that "/etc/fstab" uses the "nodev" option on all nonroot local partitions.
