CVE-2023-20588

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

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-2021-46754

Insufficient input validation in the ASP (AMDSecure Processor) bootloader may allow an attacker with a compromised Uapp orABL to coerce the bootloader into exposing sensitive information to the SMU(System Management Unit) resulting in a potential loss of confidentiality andintegrity.

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-2021-46753

Failure to validate the length fields of the ASP(AMD Secure Processor) sensor fusion hub headers may allow an attacker with amalicious Uapp or ABL to map the ASP sensor fusion hub region and overwritedata structures leading to a potential loss of confidentiality and integrity.

CVE-2021-46794

Insufficient bounds checking in ASP (AMD SecureProcessor) may allow for an out of bounds read in SMI (System ManagementInterface) mailbox checksum calculation triggering a data abort, resulting in apotential denial of service.

CVE-2021-46792

Time-of-check Time-of-use (TOCTOU) in theBIOS2PSP command may allow an attacker with a malicious BIOS to create a racecondition causing the ASP bootloader to perform out-of-bounds SRAM reads uponan S3 resume event potentially leading to a denial of service.

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.

CVE-2021-46759

Improper syscall input validation in AMD TEE(Trusted Execution Environment) may allow an attacker with physical access andcontrol of a Uapp that runs under the bootloader to reveal the contents of theASP (AMD Secure Processor) bootloader accessible memory to a serial port,resulting in a potential l...

CVE-2021-46749

Insufficient bounds checking in ASP (AMD SecureProcessor) may allow for an out of bounds read in SMI (System ManagementInterface) mailbox checksum calculation triggering a data abort, resulting in apotential denial of service.
