Details

The freevxfs filesystem type is a free version of the Veritas type filesystem. This is the

primary filesystem type for HP-UX operating systems.

*Rationale*

Removing support for unneeded filesystem types reduces the local attack surface of the

server. If this filesystem type is not needed, disable it.

Solution

Edit or create the file /etc/modprobe.d/CIS.conf and add the following line-install freevxfs /bin/true
