AMD’s virtual machine encryption bypassed – NOPE!

AMD’s Epyc server chips utilize Secure Encrypted Virtualization (SEV) to automatically encrypt virtual machines on the fly while stored in memory, but researchers now say that they can get around it with a technique dubbed SEVer: “miscreants at the host level can alter a guest’s physical memory mappings, using standard page tables, so that the SEV mechanism fails to properly isolate and scramble parts of the VM in RAM“.

AMD responded in a community post what’s really behind the claims from CTS-Labs – AMD makes it very clear that the issues identified by CTS-Labs research have very less to do with Meltdown & Spectre security holes, but there also telling us that these are associated with the firmware that manages the AMD Secure Processor (PSP) – similar to Intel’s ME. The chipset used in some AM4 and TR4 motherboards as well as others are getting a firmware patches (BIOS updates) for this.
