Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/write from/to an invalid DRAM address, potentially resulting in denial-of-service.
CVE-2023-20592 2 Amd, Redhat 141 Epyc 7001, Epyc 7001 Firmware, Epyc 7203 and 138 more 2024-10-11 6.5 Medium
Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU leading to a potential loss of guest virtual machine (VM) memory integrity.
CVE-2023-20578 1 Amd 218 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 215 more 2024-10-02 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.
CVE-2023-20591 1 Amd 64 Epyc 7003 Firmware, Epyc 7203 Firmware, Epyc 7203p Firmware and 61 more 2024-08-14 6.5 Medium
Improper re-initialization of IOMMU during the DRTM event may permit an untrusted platform configuration to persist, allowing an attacker to read or modify hypervisor memory, potentially resulting in loss of confidentiality, integrity, and availability.
CVE-2024-21980 1 Amd 64 Epyc 7003 Firmware, Epyc 7203 Firmware, Epyc 7203p Firmware and 61 more 2024-08-06 7.9 High
Improper restriction of write operations in SNP firmware could allow a malicious hypervisor to potentially overwrite a guest's memory or UMC seed resulting in loss of confidentiality and integrity.
CVE-2024-21978 1 Amd 64 Epyc 7003 Firmware, Epyc 7203 Firmware, Epyc 7203p Firmware and 61 more 2024-08-06 6 Medium
Improper input validation in SEV-SNP could allow a malicious hypervisor to read or overwrite guest memory potentially leading to data leakage or data corruption.
CVE-2021-26345 1 Amd 180 Epyc 7203, Epyc 7203 Firmware, Epyc 7203p and 177 more 2024-08-03 1.9 Low
Failure to validate the value in APCB may allow a privileged attacker to tamper with the APCB token to force an out-of-bounds memory read potentially resulting in a denial of service.
