Funny that I am seeing this now, because last Fall I had Daniel Genkin as my Intro to Cyber Security Professor (co-author of this result). Interesting class, but I remember him mentioning that they were working on a speculative attack for Apple CPUs after seeing the results of spectre and meltdown on Intel CPUs. I remember how he seemed almost paranoid about security, and I suppose I see why now (security is almost never guaranteed).

Especially now that I have just bought an M4 mac

Am curious if the problem impacts m4 given it came out after this was released and disclosed.

That and it moved to Arm’s 9.2 instructions.

Keep in mind that it takes at least 3 months to produce an M4, and the design has been finalized long before that. So most likely yes

Yes.
