CVE-2023-20588

A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality.

CVE-2021-26316

Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution.

CVE-2020-12965

When combined with specific software sequences, AMD CPUs may transiently execute non-canonical loads and store using only the lower 48 address bits potentially resulting in data leakage.

CVE-2023-20521

TOCTOU in the ASP Bootloader may allow an attacker with physical access to tamper with SPI ROM records after memory content verification, potentially leading to loss of confidentiality or a denial of service.

CVE-2022-23815

Improper bounds checking in APCB firmware may allow an attacker to perform an out of bounds write, corrupting the APCB entry, potentially leading to arbitrary code execution.

CVE-2023-20555

Insufficient input validation inCpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwritingan arbitrary bit in an attacker-controlled pointer potentially leading toarbitrary code execution in SMM.

CVE-2021-26367

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.

CVE-2023-20589

An attacker with specialized hardware and physical access to an impacted device may be able to perform a voltage fault injection attack resulting in compromise of the ASP secure boot potentially leading to arbitrary code execution.
