I still remember hearing about a Ring 0 exploit in Windows (I may be misremembering, though) that required Ring 0 access. I think if an attacker has access to Ring 0, you’re already screwed anyway.

I agree, all this attention grabbing sound to me as if this is actually not a big deal. But we will see i guess.

A 9.9 is pretty bad no matter what. They wouldn’t rank it almost a 10 if it was some obscure bug that is very hard to exploit.

With that being said it is hard to know without details
