CVE-2023-20588

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

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.
