Insufficient input validation in the ABL may allow a privileged attacker with access to the BIOS menu or UEFI shell to tamper with the structure headers in SPI ROM causing an out of bounds memory read and write, potentially resulting in memory corruption or denial of service.
Insufficient input validation in the SMU may allow an attacker to corrupt SMU SRAM potentially leading to a loss of integrity or denial of service.
An integer overflow in the SMU could allow a privileged attacker to potentially write memory beyond the end of the reserved dRAM area resulting in loss of integrity or availability.
