CVE-2023-52712
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 potentiall...
CVE-2023-52711
CVE-2023-52711 involves an exposed SMI handler in AMD’s PspP2CmboxV2 firmware (AmdPspP2CmboxV2) that can bypass protections from prior UEFI phases and grant direct access to SPI flash. Additionally, the issue can leak and corrupt SMM memory, potentially enabling code execution in SMM. Connected s...
