Ryzenfall and Masterkey together provide a complete break of the PSP authentication with arbitrary code execution if you are running a vulnerable AGESA. You will of course have to flash downwards to a vulnerable version but it should give you what you need. Also, as this was fixed prior to Zen2 then you wouldn’t be able to test their newer chips. Basically AMD has a buffer overflow in a SMM call and they conveniently signed an empty PSP module payload that will be executed nevertheless. https://youtu.be/QuqefIZrRWc https://youtu.be/QuqefIZrRWc
