CVE-2025-54509 1 Amd 6 Epyc 8004 Series Processors, Epyc 9004 Series Processors, Epyc 9005 Series Processors and 3 more 2026-07-31 N/A
Improper access control for register interface in the Input-Output Memory Management Unit (IOMMU) could allow a privileged attacker to cause non-coherent accesses by the AMD Secure Processor (ASP), potentially resulting in loss of integrity.
CVE-2025-54518 1 Amd 11 Epyc 7002 Series Processors, Epyc Embedded 7002 Series Processors, Ryzen 3000 Series Desktop Processors and 8 more 2026-05-15 N/A
Improper isolation of shared resources within the CPU operation cache on Zen 2-based products could allow an attacker to corrupt instructions executed at a different privilege level, potentially resulting in privilege escalation.
CVE-2021-26383 1 Amd 9 Instinct Mi210, Instinct Mi250, Radeon Pro V520 and 6 more 2026-04-15 7.9 High
Insufficient bounds checking in AMD TEE (Trusted Execution Environment) could allow an attacker with a compromised userspace to invoke a command with malformed arguments leading to out of bounds memory access, potentially resulting in loss of integrity or availability.
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-2021-46778 1 Amd 358 Athlon 3050ge, Athlon 3050ge Firmware, Athlon 3150g and 355 more 2024-11-21 5.6 Medium
Execution unit scheduler contention may lead to a side channel vulnerability found on AMD CPU microarchitectures codenamed “Zen 1”, “Zen 2” and “Zen 3” that use simultaneous multithreading (SMT). By measuring the contention level on scheduler queues an attacker may potentially leak sensitive information.
CVE-2021-26318 1 Amd 10 Athlon, Athlon Firmware, Athlon Pro and 7 more 2024-11-21 4.7 Medium
A timing and power-based side channel attack leveraging the x86 PREFETCH instructions on some AMD CPUs could potentially result in leaked kernel address space information.
