RHEL-10-400355 - RHEL 10 must prevent device files from being interpreted on file systems that contain user home directories.
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 RHEL 10 to prevent device files from being interpreted on file systems that contain user home directories.Modify "/etc/fstab" to use the "nodev" option on the "/home" directory.
