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.

hw: amd: AMD Radeon Graphics Kernel Driver Privilege Management Vulnerability

An improper privilege management in the AMD Radeon™ Graphics driver may allow an authenticated attacker to craft an IOCTL request to gain I/O control over arbitrary hardware ports or physical addresses resulting in a potential arbitrary code execution.
