Fix Recommendation

Prevent the USB drivers from loading:
# echo "exclude: usb_ac" >> /etc/system
# echo "exclude: usb_as" >> /etc/system
# echo "exclude: hid" >> /etc/system
# echo "exclude: scsa2usb" >> /etc/system
# echo "exclude: usbprn" >> /etc/system
# echo "exclude: usbser_edge" >> /etc/system

The system must be restarted for these changes to take effect.

Check Contents

If the system needs a particular USB driver for storage, this vulnerability is not applicable.

Check the current loaded kernel modules:

# modinfo | grep usb_ac
# modinfo | grep usb_as
# modinfo | grep hid
# modinfo | grep scsa2usb
# modinfo | grep usbprn
# modinfo | grep usbser_edge

If any command produces output, this is a finding.

Check the configuration of the /etc/system file:

# grep 'exclude: usb_ac' /etc/system
# grep 'exclude: usb_as' /etc/system
# grep 'exclude: hid' /etc/system
# grep 'exclude: scsa2usb' /etc/system
# grep 'exclude: usbprn' /etc/system
# grep 'exclude: usbser_edge' /etc/system

If no results are returned from any particular command, this is a finding.
