This seems like yet another thing on the list of “x86 hardware issues that sound worse than they are”.

I’m interested to see what people are able to reverse engineer with these sorts of tools. It wasn’t even that long ago that ucode wasn’t even encrypted with integrity. I don’t think AMD started doing that until around 2010.

I’m also curious which hardware versions this works on, since it’s not obvious it’s universal. I’ll be amused if it’s some forlorn low power chip from 10 years ago.
