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

• CVE-2020-12965, published 2022-02-04. High severity, CVSS 7.5. EPSS: 2.4% chance of exploitation in the next 30 days. When combined with specific software sequences, AMD CPUs may transiently execute non-canonical loads and store using only the lower 48 address bits potentially resulting in data leakage.
• CVE-2021-26317, published 2022-05-12. High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days. Failure to verify the protocol in SMM may allow an attacker to control the protocol and modify SPI flash resulting in a potential arbitrary code execution.
• CVE-2021-26316, published 2023-01-11. High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days. Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code…
• CVE-2021-26366, published 2022-05-12. High severity, CVSS 7.1. EPSS: 0.2% chance of exploitation in the next 30 days. An attacker, who gained elevated privileges via some other vulnerability, may be able to read data from Boot ROM resulting in a loss of system integrity.
• CVE-2021-26369, published 2022-05-12. High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days. A malicious or compromised UApp or ABL may be used by an attacker to send a malformed system call to the bootloader, resulting in out-of-bounds memory accesses.
• CVE-2021-26361, published 2022-05-12. Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days. A malicious or compromised User Application (UApp) or AGESA Boot Loader (ABL) could be used by an attacker to exfiltrate arbitrary memory from the ASP stage 2 bootloader potentially leading to…
• CVE-2021-46778, published 2022-08-10. Medium severity, CVSS 5.6. EPSS: 0.2% chance of exploitation in the next 30 days. Execution unit scheduler contention may lead to a side channel vulnerability found on AMD CPU microarchitectures codenamed “Zen 1”, “Zen 2” and “Zen 3” that use simultaneous multithreading (SMT). By…
• CVE-2021-26362, published 2022-05-12. High severity, CVSS 7.1. EPSS: 0.2% chance of exploitation in the next 30 days. A malicious or compromised UApp or ABL may be used by an attacker to issue a malformed system call which results in mapping sensitive System Management Network (SMN) registers leading to a loss of…
