Insufficient input validation in the SMU may allow an attacker to improperly lock resources, potentially resulting in a denial of service.

Insufficient bound checks in the SMU may allow an attacker to update the SRAM from/to address space to an invalid value potentially resulting in a denial of service.

Insufficient input validation of BIOS mailbox messages in SMU may result in out-of-bounds memory reads potentially resulting in a denial of service.

Insufficient bound checks in the SMU may allow an attacker to update the from/to address space to an invalid value potentially resulting in a denial of service.

Insufficient input validation in the SMU may allow a physical attacker to exfiltrate SMU memory contents over the I2C bus potentially leading to a loss of confidentiality.

Improper syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory out-of-bounds, potentially leading to a denial-of-service.

Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory outside the bounds of a mapped register potentially leading to a denial of service.

TOCTOU in the ASP may allow a physical attacker to write beyond the buffer bounds, potentially leading to a loss of integrity or denial of service.

Improper input validation and bounds checking in SEV firmware may leak scratch buffer bytes leading to potential information disclosure.

Insufficient bounds checking in ASP (AMD Secure Processor) firmware while handling BIOS mailbox commands, may allow an attacker to write partially-controlled data out-of-bounds to SMM or SEV-ES regions which may lead to a potential loss of integrity and availability.
