It's been a rough few weeks for CPU vendors as far as security vulnerabilities go. Just days ago, I wrote about the Downfall vulnerability that affects Intel's 6th through to 11th Generation chips, and just as importantly how a patch can dramatically affect performance. Now it's AMD's turn to take some pain.
AMD's Zen 3 and Zen 4 CPUs are affected by what is known as the 'Inception' vulnerability. Like many recent attacks, this one is a side channel attack that can lead to the exposure of otherwise secure data. AMD says its Zen 1 and Zen 2 generations are unaffected.
