Release of Technical Report into the AMD Security Processor

Posted by James Forshaw, Google Project Zero Today, members of Project Zero and the Google Cloud security team are releasing a technical report on a security review of AMD Secure Processor ASP. The ASP is an isolated ARM processor in AMD EPYC CPUs that adds a root of trust and controls secure...

A flaw was found in the KVM's AMD code for supporting the Secure Encrypted Virtualization-Encrypted State (SEV-ES). A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via a malicious VMGEXIT for a string I/O instruction (for example outs or ins) using the exit reason SVM_EXIT_IOIO. This issue results in a crash of the entire system or a potential guest-to-host escape scenario.
