A newly discovered vulnerability in AMD chips allows malicious actors to perform remote code execution (RCE) and privilege escalation in virtual machines.
Cybersecurity researchers from the CISPA Helmholtz Center for Information Security in Germany detailed a vulnerability they named StackWarp, a hardware vulnerability in AMD CPUs that breaks the protections of confidential virtual machines, by manipulating how the processor tracks the stack, and letting a malicious insider or hypervisor change program flow or read sensitive data inside a protected VM.
