Known exploited (CISA KEV) first, then by EPSS exploit probability.

• CVE-2021-26365, published 2023-05-09. High severity, CVSS 8.2. EPSS: 0.6% chance of exploitation in the next 30 days. Certain size values in firmware binary headers could trigger out of bounds reads during signature validation, leading to denial of service or potentially limited leakage of information…
• CVE-2021-26392, published 2022-11-09. High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days. Insufficient verification of missing size check in 'LoadModule' may lead to an out-of-bounds write potentially allowing an attacker with privileges to gain code execution of the OS/kernel by loading…
• CVE-2020-12931, published 2022-11-09. High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days. Improper parameters handling in the AMD Secure Processor (ASP) kernel may allow a privileged attacker to elevate their privileges potentially leading to loss of integrity.
• CVE-2020-12930, published 2022-11-09. High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days. Improper parameters handling in AMD Secure Processor (ASP) drivers may allow a privileged attacker to elevate their privileges potentially leading to loss of integrity.
• CVE-2021-26393, published 2022-11-09. Medium severity, CVSS 5.5. EPSS: 0.3% chance of exploitation in the next 30 days. Insufficient memory cleanup in the AMD Secure Processor (ASP) Trusted Execution Environment (TEE) may allow an authenticated attacker with privileges to generate a valid signed TA and potentially…
• CVE-2023-20521, published 2023-11-14. Medium severity, CVSS 5.7. EPSS: 0.3% chance of exploitation in the next 30 days. 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…
• CVE-2021-26371, published 2023-05-09. Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days. A compromised or malicious ABL or UApp could send a SHA256 system call to the bootloader, which may result in exposure of ASP memory to userspace, potentially leading to information…
• CVE-2021-26354, published 2023-05-09. Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days. Insufficient bounds checking in ASP may allow an attacker to issue a system call from a compromised ABL which may cause arbitrary memory values to be initialized to zero, potentially leading to…
