USB: whiteheat: Added bounds checking for bulk command response
commit 6817ae225cd650fb1c3295d769298c38b1eba818 upstream.
This patch fixes a potential security issue in the whiteheat USB driver
which might allow a local attacker to cause kernel memory corrpution. This
is due to an unchecked memcpy into a fixed size buffer (of 64 bytes). On
EHCI and XHCI busses it's possible to craft responses greater than 64
bytes leading a buffer overflow.
