Attack that defeats AMD chip security possible, unlikely

AMD likes to crow about how its Epyc server processors can encrypt the content of virtal machines while they’re in operation so they are secure and isolated, preventing other VMs on the processor from accessing the encrypted contents.

Well, researchers from the Technical University of Berlin have found a weakness in that feature, known as Secure Encrypted Virtualization (SEV), and published a theoretical attack that defeats the protection.

The paper ”One Glitch to Rule Them All: Fault Injection Attacks Against AMD’s Secure Encrypted Virtualization” details how the researchers succeeded in mounting a voltage fault-injection attack.
