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-2023-20589, published 2023-08-08. Medium severity, CVSS 6.8. EPSS: 0.6% chance of exploitation in the next 30 days. An attacker with specialized hardware and physical access to an impacted device may be able to perform a voltage fault injection attack resulting in compromise of the ASP secure boot potentially…
• CVE-2023-20555, published 2023-08-08. High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days. 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…
• 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-2022-23817, published 2024-08-13. High severity, CVSS 7.3. EPSS: 0.2% chance of exploitation in the next 30 days. Insufficient checking of memory buffer in AMD Secure Processor (ASP) Secure OS may allow an attacker with a malicious trusted application to read/write to the ASP Secure OS kernel virtual address…
• CVE-2022-23815, published 2024-08-13. High severity, CVSS 8.2. EPSS: 0.2% chance of exploitation in the next 30 days. Improper bounds checking in APCB firmware may allow an attacker to perform an out of bounds write, corrupting the APCB entry, potentially leading to arbitrary code execution.
• CVE-2021-26367, published 2024-08-13. Medium severity, CVSS 6.0. EPSS: 0.2% chance of exploitation in the next 30 days. A malicious attacker in x86 can misconfigure the Trusted Memory Regions (TMRs), which may allow the attacker to set an arbitrary address range for the TMR, potentially leading to a loss of integrity…
