Haven’t we been here before? It seems like it’s very similar to the branch prediction exploits of the late 2010s. Is there something particularly novel about this class of exploits?
Then people say "no that's not possible, we got security in place."
So then the researchers showcase a new demo where they use their existing knowledge with the same issue (i.e. scaling-induced voltage leaks).
I suspect this will go on and on for decades to come.
