Amd Ryzen 2300X Firmware vulnerabilities

CVE-2021-46754 [CRITICAL] CWE-20 CVE-2021-46754: Insufficient input validation in the ASP (AMD Secure Processor) bootloader may allow an attacker wit Insufficient input validation in the ASP (AMD Secure Processor) bootloader may allow an attacker with a compromised Uapp or ABL to coerce the bootloader into exposing sensitive information to the SMU (System Management Unit) resulting in a potential loss of confidentiality and integrity.

CVE-2021-46753 [CRITICAL] CVE-2021-46753: Failure to validate the length fields of the ASP (AMD Secure Processor) sensor fusion hub headers ma Failure to validate the length fields of the ASP (AMD Secure Processor) sensor fusion hub headers may allow an attacker with a malicious Uapp or ABL to map the ASP sensor fusion hub region and overwrite data structures leading to a potential loss of confidentiality and integrity.

CVE-2021-46749 [HIGH] CWE-125 CVE-2021-46749: Insufficient bounds checking in ASP (AMD Secure Processor) may allow for an out of bounds read in SM Insufficient bounds checking in ASP (AMD Secure Processor) may allow for an out of bounds read in SMI (System Management Interface) mailbox checksum calculation triggering a data abort, resulting in a potential denial of service.

CVE-2021-46773 [HIGH] CWE-20 CVE-2021-46773: Insufficient input validation in ABL may enable a privileged attacker to corrupt ASP memory, potenti Insufficient input validation in ABL may enable a privileged attacker to corrupt ASP memory, potentially resulting in a loss of integrity or code execution.

CVE-2021-46794 [HIGH] CWE-125 CVE-2021-46794: Insufficient bounds checking in ASP (AMD Secure Processor) may allow for an out of bounds read in SM Insufficient bounds checking in ASP (AMD Secure Processor) may allow for an out of bounds read in SMI (System Management Interface) mailbox checksum calculation triggering a data abort, resulting in a potential denial of service.

CVE-2021-46759 [MEDIUM] CWE-787 CVE-2021-46759: Improper syscall input validation in AMD TEE (Trusted Execution Environment) may allow an attacker w Improper syscall input validation in AMD TEE (Trusted Execution Environment) may allow an attacker with physical access and control of a Uapp that runs under the bootloader to reveal the contents of the ASP (AMD Secure Processor) bootloader accessible memory to a serial port, resulting in a potential loss of integrity.

CVE-2021-46792 [MEDIUM] CWE-367 CVE-2021-46792: Time-of-check Time-of-use (TOCTOU) in the BIOS2PSP command may allow an attacker with a malicious BI Time-of-check Time-of-use (TOCTOU) in the BIOS2PSP command may allow an attacker with a malicious BIOS to create a race condition causing the ASP bootloader to perform out-of-bounds SRAM reads upon an S3 resume event potentially leading to a denial of service.
