Today we reveal StackWarp: a new CPU vulnerability exploiting a synchronization bug in AMD’s stack engine across Zen 1–5 CPUs. It enables deterministic manipulation of Confidential VM's stack pointer, allowing RCE and privilege escalation via both control- and data-flow hijacking.
Even highly protected Confidential VMs aren‘t as isolated as expected. CISPA researcher @rayiizzz.bsky.social and his colleagues from the group of @misc0110.bsky.social introduce StackWarp, a new attack against AMD Zen 1–5 CPUs that breaks the integrity of Confidential VMs. stackwarpattack.com
