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.

CVE-2021-4093

CVE-2021-4093 : A flaw in the KVM AMD SEV-ES code allows a malicious VM using SEV-ES to trigger out-of-bounds reads/writes in the host kernel via a VMGEXIT with a string I/O instruction (e.g., outs/ins) using exit reason SVM_EXIT_IOIO. This can crash the host or enable a guest-to-host escape. Aff...
