Secret-key disclosure via uncleared bootloader SRAM

Improper cleanup in the AMD Secure Processor bootloader on affected AMD processors allows local privileged users to read secret keys from ASP SRAM. The bootloader fails to erase sensitive key material from its SRAM after use, leaving residual secrets available through later privileged memory access. Exploitation requires local high privileges and high-complexity access to ASP SRAM; the reported consequence is confidentiality loss only.
