• CVE-2024-36349, published 2025-07-08. Low severity, CVSS 3.8. EPSS: 0.2% chance of exploitation in the next 30 days. A transient execution vulnerability in some AMD processors may allow a user process to infer TSC_AUX even when such a read is disabled, potentially resulting in information leakage.
• CVE-2025-54505, published 2026-04-27. Low severity, CVSS 2.0. EPSS: 0.2% chance of exploitation in the next 30 days. A transient execution vulnerability within AMD CPUs may allow a local user-privileged attacker to leak data via the floating point divisor unit, potentially resulting in loss of confidentiality.
• CVE-2025-29950, published 2026-02-10. High severity, CVSS 7.1. EPSS: 0.2% chance of exploitation in the next 30 days. Improper input validation in system management mode (SMM) could allow a privileged attacker to overwrite stack memory leading to arbitrary code execution.
• CVE-2024-36354, published 2025-09-06. High severity, CVSS 7.5. EPSS: 0.2% chance of exploitation in the next 30 days. Improper input validation for DIMM serial presence detect (SPD) metadata could allow an attacker with physical access, ring0 access on a system with a non-compliant DIMM, or control over the Root of…
• CVE-2021-46746, published 2024-08-13. Medium severity, CVSS 5.2. EPSS: 0.2% chance of exploitation in the next 30 days.
