Descriptions
In the AMD SEV/SEV-ES feature, memory can be rearranged in the guest address space that is not detected by the attestation mechanism which could be used by a malicious hypervisor to potentially lead to arbitrary code execution within the guest VM if a malicious administrator has access to compromise the server hypervisor.
En la funcionalidad SEV/SEV-ES de AMD, la memoria puede ser reorganizada en el espacio de direcciones del invitado que no es detectado por el mecanismo de certificación que podría ser utilizado por un hypervisor malicioso para conllevar potencialmente a una ejecución de código arbitraria dentro de la VM invitada si un administrador malicioso tiene acceso para comprometer el hypervisor del servidor
