That's not really true all of the time, some AMD fTPMs have physical vulnerabilities for example, that allow compromising the entire thing with some tools and a few hours of time. Software can't fix this since it's a flaw in the hardware itself, you'd need to buy new hardware to fix this.

- Nextgrid 3y agoThanks, very interesting. Is there a distilled version of this or an announcement with a list of vulnerable chips?
- chlorion 3y agoI don't seem to have bookmarked anything except for the link I posted earlier and the HN thread that discussed this (posted below). From my memory it was every zen module up to and including zen3. It's possible that zen4 has been fixed but I'm not certain about that. There is a "requirements" section of the PDF that talks a little bit more about which CPUs were effected but that isn't distilled! https://news.ycombinator.com/item?id=35787195 https://news.ycombinator.com/item?id=35787195
