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

• CVE-2023-20569, published 2023-08-08. Medium severity, CVSS 4.7. EPSS: 7.3% chance of exploitation in the next 30 days. A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address,…
• CVE-2023-4969, published 2024-01-16. Medium severity, CVSS 6.5. EPSS: 1.2% chance of exploitation in the next 30 days. A GPU kernel can read sensitive data from another GPU kernel (even from another user or app) through an optimized GPU memory region called _local memory_ on various architectures.
• CVE-2023-20596, published 2023-11-14. Critical severity, CVSS 9.8. EPSS: 1% chance of exploitation in the next 30 days. Improper input validation in the SMM Supervisor may allow an attacker with a compromised SMI handler to gain Ring0 access potentially leading to arbitrary code execution.
• CVE-2022-23821, published 2023-11-14. Critical severity, CVSS 9.8. EPSS: 1% chance of exploitation in the next 30 days. Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution.
• CVE-2022-23820, published 2023-11-14. Critical severity, CVSS 9.8. EPSS: 0.7% chance of exploitation in the next 30 days. Failure to validate the AMD SMM communication buffer may allow an attacker to corrupt the SMRAM potentially leading to arbitrary code execution.
• 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-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-2023-20571, published 2023-11-14. High severity, CVSS 8.1. EPSS: 0.4% chance of exploitation in the next 30 days. A race condition in System Management Mode (SMM) code may allow an attacker using a compromised user space to leverage CVE-2018-8897 potentially resulting in privilege escalation.
• CVE-2021-46758, published 2023-11-14. Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days. Insufficient validation of SPI flash addresses in the ASP (AMD Secure Processor) bootloader may allow an attacker to read data in memory mapped beyond SPI flash resulting in a potential loss of…
• 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…
