Security Flaw in AMD's Secure Chip-On-Chip Processor Disclosed Online

AMD has fixed, but not yet released BIOS/UEFI/firmware updates for the general public for a security flaw affecting the AMD Secure Processor.

This component, formerly known as AMD PSP (Platform Security Processor), is a chip-on-chip security system, similar to Intel's much-hated Management Engine (ME).

Just like Intel ME, the AMD Secure Processor is an integrated coprocessor that sits next to the real AMD64 x86 CPU cores and runs a separate operating system tasked with handling various security-related operations.
