Highest priority

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

• CVE-2023-20588, published 2023-08-08. Medium severity, CVSS 5.5. EPSS: 11.2% chance of exploitation in the next 30 days. A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality. 
• 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-2021-26316, 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…
