Local Privilege Attack via AGESA Bootloader PMIC Leads to Memory Denial of Service

Insecure default configuration state of DDR5 memory module by AGESA Bootloader Firmware could allow an attacker with local user privilege to abuse the unprotected PMIC interface to create a permanent denial of service condition or affect the integrity of the memory module.

AMD Platform Configuration Blob: APCB SMM driver: kernel: linux-firmware: AMD APCB SMM driver: Arbitrary Code Execution via incorrect boot service use

Incorrect use of boot service in the AMD Platform Configuration Blob (APCB) SMM driver could allow a privileged attacker with local access (Ring 0) to achieve privilege escalation potentially resulting in arbitrary code execution.

Improper isolation of shared resources on a system on a chip by a malicious local attacker with high privileges could potentially lead to a partial loss of integrity.
