RHEL 10 must prevent special devices on nonroot local partitions.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
| V-281248 | RHEL-10-700200 | SV-281248r1166696_rule | CCI-001764 | medium |
| Description | ||||
| 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. | ||||

Details
Check Text (C-281248r1166696_chk)
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 Text (F-85714r1166695_fix)
Configure RHEL 10 so that "/etc/fstab" uses the "nodev" option on all nonroot local partitions.
