| CVE-2024-36354 | 1 Amd | 11 Athlon, Athlon 3000, Epyc and 8 more | 2026-04-15 | 7.5 High |
| 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 Trust for BIOS update, to bypass SMM isolation potentially resulting in arbitrary code execution at the SMM level. | ||||
| CVE-2025-29939 | 1 Amd | 8 Epyc 7003 Series Processors, Epyc 8004 Series Processors, Epyc 9004 Series Processors and 5 more | 2026-04-15 | N/A |
| Improper access control in secure encrypted virtualization (SEV) could allow a privileged attacker to write to the reverse map page (RMP) during secure nested paging (SNP) initialization, potentially resulting in a loss of guest memory confidentiality and integrity. | ||||
| CVE-2024-36355 | 1 Amd | 25 Epyc 9004 Series Processors, Epyc Embedded 9004 Series Processors, Ryzen 5000 Series Desktop Processors and 22 more | 2026-04-15 | N/A |
| Improper input validation in the SMM handler could allow an attacker with Ring0 access to write to SMRAM and modify execution flow for S3 (sleep) wake up, potentially resulting in arbitrary code execution. | ||||
| CVE-2024-21977 | 1 Amd | 11 Epyc, Epyc 7003, Epyc 8004 and 8 more | 2026-04-15 | 3.2 Low |
| Incomplete cleanup after loading a CPU microcode patch may allow a privileged attacker to degrade the entropy of the RDRAND instruction, potentially resulting in loss of integrity for SEV-SNP guests. | ||||
| CVE-2023-20578 | 1 Amd | 218 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 215 more | 2025-03-18 | 7.5 High |
| A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow an attacker with ring0 privileges and access to the BIOS menu or UEFI shell to modify the communications buffer potentially resulting in arbitrary code execution. | ||||
