RHEL-09-231200 - RHEL 9 must prevent special devices on non-root local partitions.
Information
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.
Solution
Configure the "/etc/fstab" to use the "nodev" option on all non-root local partitions.See Also
