this sounds exciting, nice that AMD found it: https://www.amd.com/en/resources/product-security/bulletin/amd-sb-7052.html AMD has identified a vulnerability in the CPU operation (op/µop) cache on Zen 2‑based products that can cause incorrect instructions to be executed at a higher privilege level. [...] Improper isolation of shared resources within the CPU operation cache on Zen 2-based products could allow an attacker to corrupt instructions executed at a different privilege level, potentially resulting in privilege escalation.
