Problem Description:
A missing length validation code common to these three drivers means that a
malicious USB device could write beyond the end of an allocated network
packet buffer.
Impact:
An attacker with physical access to a USB port and the ability to bring a
network interface up may be able to use a specially crafted USB device to
gain kernel or user-space code execution.
