• CVE-2023-20577 High 7.4 A heap overflow in SMM module may allow an attacker with access to a second vulnerability that enables writing to SPI flash, potentially resulting in arbitrary code execution. 0.2%
• CVE-2024-36347 Medium 6.4 Improper signature verification in AMD CPU ROM microcode patch loader may allow an attacker with local administrator privilege to load malicious microcode, potentially resulting in loss of integrity o 0.1%
• CVE-2024-21925 High 8.2 Improper input validation within the AmdPspP2CmboxV2 driver may allow a privileged attacker to overwrite SMRAM, leading to arbitrary code execution. 0.2%
• CVE-2023-20578 High 7.5 A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow an attacker with ring0 privileges and access to the BIOS menu or UEFI shell to modify the communications buffer potentially resulting in arbitrary 0.1%
• CVE-2023-31315 High 7.5 Improper validation in a model specific register (MSR) could allow a malicious program with ring0 access to modify SMM configuration while SMI lock is enabled, potentially leading to arbitrary code ex 0.6%
• CVE-2022-23829 High 8.2 A potential weakness in AMD SPI protection features may allow a malicious attacker with Ring0 (kernel mode) access to bypass the native System Management Mode (SMM) ROM protections. 0.2%
• CVE-2023-20526 Low 1.9 Insufficient input validation in the ASP Bootloader may enable a privileged attacker with physical access to expose the contents of ASP memory potentially leading to a loss of confidentiality. 0.3%
• CVE-2023-20521 Low 3.3 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 0.3%
• CVE-2021-46774 Medium 6.7 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. 0.5%
