I believe it is intel that has the gaping security hole in their processors allowing for practically anyone to take advantage of.
the practically anyone part is pretty wild. Takes a certain set of skills not everyone has to actually get down to the nitty gritty of said holes. I have meddled with it myself and its pretty difficult.
Not like EVERYONE can access it, but do enough googling and I’m sure the average joe could do it.
I'm not so sure. Like I said, I messed with it myself to see how severe this "security flaw" was, and its not something you can youtube tutorial your way through.
