Verify that the "/boot" mount point has the "nodev" option is with the following command:

$ mount | grep '\s/boot\s'

/dev/sda2 on /boot type xfs (rw,nosuid,nodev,noexec,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota)

If the "/boot" file system does not have the "nodev" option set, this is a finding.
