According to him, billions of Intel processors are affected, which are used in private user computers as well as in cloud servers.
Update: Intel’s Downfall was closely followed by AMD’s Inception, a newfound security hole affecting all Ryzen and Epyc processors.

so both desktop and server chips are affected on both cpu manufacturers products. can't take any measures if your password is online on some server.

I was going to say, AMD had a flaw of similar severity. And they won't have a fix for a few months for most affected CPUs, and that fix will likely incur a loss in performance.

Basically it sounds like both of these flaws are due to the security chip. I can't help but feel like these flaws are by design. /tinfoil

Downfall was disclosed to Intel a year ago but was on embargo until this week. Can't help but suspect that Intel waited for AMD to be impacted by a similar event to reveal downfall

From what I’m reading, Inception is a pretty minor vulnerability, especially compared to downfall.
