ZeroPeril security researcher Kyriakos Economou has revealed that he has found a driver vulnerability in several AMD chipsets.

The bug allows attackers to extract information from RAM via the Platform Security Processor (PSP) in AMD CPUs. It seems to only apply to the Windows driver.

 

This allows sensitive information such as passwords to be stolen.

The PSP is AMD's take on Intel's SGX enclave and is the part of the memory that the processor entrusts with sensitive information.

When Windows communicates with the enclave, it does so through the kernel driver amdsps.sys
