A vulnerability in AMD CPU allows bypassing the SEV (Secure Encrypted Virtualization) protection mechanism.
Researchers at the Helmholtz Center for Information Security (CISPA) have published a new attack method called CacheWarp, which allows compromising the AMD SEV (Secure Encrypted Virtualization) protection mechanism used in virtualization systems to safeguard virtual machines from interference by the hypervisor or the host system administrator. The proposed method enables an attacker with hypervisor access to execute arbitrary code and escalate privileges within the virtual machine, […]
