The f00f bug is one that was discovered when cmpxchg didn't do what it was supposed to. If this just searches the space looking for packets that shouldn't decode but end up getting executed, then it's unlikely to be anywhere as interesting as f00f. In all likelihood we have already seen 2017's big silicon bug and it was AMD's Ryzen 7 1800X issue.
