Can anyone add any details? The article is very very vague. Doesn't this work thru the Ethernet port in the chipset silicon? So if you're running a desktop that has a physical Ethernet card in it, and the Intel Ethernet isn't connected, are you OK? And if you're running on a laptop that uses Intel's Ethernet, (and most of them do?) then are you vulnerable?
