• 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-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-2023-20565, published 2023-11-14. High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days. Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access.
• CVE-2023-20563, published 2023-11-14. High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days. Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access.
• CVE-2023-20579, published 2024-02-13. Medium severity, CVSS 6.0. EPSS: 0.2% chance of exploitation in the next 30 days. Improper Access Control in the AMD SPI protection feature may allow a user with Ring0 (kernel mode) privileged access to bypass protections potentially resulting in loss of integrity and…
