I suspect based on what I have already read (likely incomplete) that the vulnerability is a lot harder to exploit than what the hype would seem to indicate. I also suspect that good infosec practices will likely make this near to impossible to exploit as the descriptions provided so far, require the execution of code to exploit.
However, having said that, shame on chip manufactures for allowing this vulnerability to even exist.
You can bet your mortgage money that the Russians, Chinese, Iranians, Norks and anybody else of like minds are writing code to exploit it this very second, top priority and no holds barred........................
