Comment on Intel 'Downfall': Severe flaw in billions of CPUs leaks passwords and much more
Gsus4@feddit.nl 1 year agoNo luck, it’s a systemic issue (practice):
Update: Intel’s Downfall was closely followed by AMD’s Inception, a newfound security hole affecting all Ryzen and Epyc processors. The first independent testing of the mitigation microcode patches show that it can drastically lower performance in certain workloads. We’ve included details throughout this post.

Is that the same as zenbleed or in addition? How easy zenbleed was to test and the kind of information gained was terrifying.

yea, it’s on top www.xda-developers.com/amd-inception/ :/

Damn. I just recently patched up my dedicated box for zenbleed. This seems far worse.
I mean I'm not going to be a high value target. But still, this isn't looking good for either chip maker right now.

My understanding is the newest AMD bug is probably not too much of an issue because it’s very limited in how much data it can leak at a time and there’s no way to target it at specific data so if you wanted to use it to do something like grab a password it’s extremely unwieldy and not really practical.
