Description

Various Issues Due To Exposed SMI Handler in AmdPspP2CmboxV2. The first issue can be leveraged to bypass the protections that have been put in place by previous UEFI phases to prevent direct access to the SPI flash. The second issue can be used to both leak and corrupt SMM memory, thus potentially leading code execution in SMM
