Improper validation of array index in Power Management Firmware (PMFW) may allow a privileged attacker to cause an out-of-bounds memory read within PMFW, potentially leading to a denial of service.

A malicious attacker in x86 can misconfigure the Trusted Memory Regions (TMRs), which may allow the attacker to set an arbitrary address range for the TMR, potentially leading to a loss of integrity and availability.

An insufficient DRAM address validation in PMFW may allow a privileged attacker to read from an invalid DRAM address to SRAM, potentially resulting in data corruption or denial of service.
