CVE-2023-20569, known as Inception or RAS Poisoning, is a hardware side-channel vulnerability affecting some AMD CPUs. An attacker may influence return-address prediction, causing speculative execution at an attacker-controlled instruction-pointer address. The resulting speculative behavior can expose information through a side channel.
