Check out what using a 40-core (160 thread) #TalosII with optional #AMD WX7100 GPU looks like! Screenshot of actual system showing Firefox, Blender, and htop under #KDE Plasma 5 on #Debian .

#AMD currently indicating RCE not possible on #PSP with this exploit. Waiting for public verification outside AMD before sounding the all-clear; we believe the fundamental design of #AMD systems with the #PSP continues to be a security and integrity risk.

Recent #AMD #PSP exploit may also open door to transparently defeating #SME (encrypted virtual memory). The #PSP manages the #SME encryption key according to #AMD documents https://social.raptorengineering.io/url/390

#AMD highly privileged #PSP vulnerable to attack, with full control of the PSP environment possible via PC manipulation. The PSP has FULL access to the entire system memory space; this theoretically allows undetectable #rootkits on ALL #AMD platforms. http://seclists.org/fulldisclosure/2018/Jan/12

And this is a good example of why @RaptorCompSys has chosen to offer open-friendly #AMD GPUs as first-class citizens for #TalosII , versus closed and locked #NVIDIA https://www.theregister.co.uk/2018/01/03/nvidia_server_gpus/ … via @theregister
