Amd Ryzen 9 5900 Firmware vulnerabilities

CVE-2022-23820 [HIGH] CWE-20 CVE-2022-23820: Failure to validate the AMD SMM communication buffer may allow an attacker to corrupt the SMRAM pote Failure to validate the AMD SMM communication buffer may allow an attacker to corrupt the SMRAM potentially leading to arbitrary code execution.

CVE-2022-23821 [CRITICAL] CVE-2022-23821: Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM po Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution.

CVE-2023-20533 [MEDIUM] CVE-2023-20533: Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/w Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/write from/to an invalid DRAM address, potentially resulting in denial-of-service.

CVE-2021-46774 [MEDIUM] CVE-2021-46774: Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/w Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/write from/to an invalid DRAM address, potentially resulting in denial-of-service.

CVE-2023-20555 [HIGH] CWE-787 CVE-2023-20555: Insufficient input validation in CpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by Insufficient input validation in CpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwriting an arbitrary bit in an attacker-controlled pointer potentially leading to arbitrary code execution in SMM.

CVE-2023-20569 [MEDIUM] CWE-203 CVE-2023-20569: A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the retur A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure.

CVE-2021-26356 [HIGH] CWE-367 CVE-2021-26356: A TOCTOU in ASP bootloader may allow an attacker to tamper with the SPI ROM following data read to m A TOCTOU in ASP bootloader may allow an attacker to tamper with the SPI ROM following data read to memory potentially resulting in S3 data corruption and information disclosure.
