Do they mean "only confirmed on Zen2", or is the problem definitely confined to only this architecture?
Is it likely that this same technique (or similar) also works on earlier (Zen/Zen+) or later (Zen3) cores, but they just haven't been able to demonstrate it yet?
- paulmd 3y agoIt's Tavis Ormandy, and he reported it to AMD, so one would assume they tried it on related hardware and it's not working.
- rincebrain 3y agoAt least the stock exploit code he provided said "nope I can't get shit to leak" on my 5900X.
- Arnavion 3y agoDoesn't repro on 2920x (Zen+).
- zacmps 3y agoI tested on a Zen 3 Epyc and wasn't able to get the POC to work, so I think it probably is just Zen 2.
