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.

CVE-2021-26373 [MEDIUM] CWE-20 CVE-2021-26373: Insufficient bound checks in the System Management Unit (SMU) may result in a system voltage malfunc Insufficient bound checks in the System Management Unit (SMU) may result in a system voltage malfunction that could result in denial of resources and/or possibly denial of service.

CVE-2021-26388 [MEDIUM] CWE-125 CVE-2021-26388: Improper validation of the BIOS directory may allow for searches to read beyond the directory table Improper validation of the BIOS directory may allow for searches to read beyond the directory table copy in RAM, exposing out of bounds memory contents, resulting in a potential denial of service.

CVE-2021-26378 [MEDIUM] CWE-119 CVE-2021-26378: Insufficient bound checks in the System Management Unit (SMU) may result in access to an invalid add Insufficient bound checks in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service.

CVE-2021-26376 [MEDIUM] CVE-2021-26376: Insufficient checks in System Management Unit (SMU) FeatureConfig may result in reenabling features Insufficient checks in System Management Unit (SMU) FeatureConfig may result in reenabling features potentially resulting in denial of resources and/or denial of service.

CVE-2021-26375 [MEDIUM] CVE-2021-26375: Insufficient General Purpose IO (GPIO) bounds check in System Management Unit (SMU) may result in ac Insufficient General Purpose IO (GPIO) bounds check in System Management Unit (SMU) may result in access/updates from/to invalid address space that could result in denial of service.
