I think the economics/ethics of the researchers are overshadowing something big:
"RYZENFALL allows malicious code to take complete control over the AMD Secure Processor."
"Multiple vulnerabilities in AMD Secure Processor firmware allow attackers to infiltrate the Secure Processor."
If this is legitimate, this is huge! The PSP could potentially be disabled! Very little work has gone into handicapping the PSP compared to the IME.
- kiddico 9y agoWell there was a big community push a while ago to have the new AMD cpus have an option to disable the PSP. I'm gonna wishfully think this was intentionally done to allow us to disable the PSP.
- fencepost 9y agoIs it wrong that my immediate reaction to that was "Wait, isn't/wasn't the PSP a portable? Did they actually use x86/x64 AMD processors in those? How?? AMD's traditionally been poor on power management!"
