Every CVE that names AMD EPYC™ Processors among its affected products, newest first. Vendors and products are as the CNA wrote them; check the affected versions on each record.
-
Improper validation of the BIOS directory may allow for searches to read beyond the directory table copy in RAM, exposing out of bounds memory contents, resulting in a potential denial of service.
- AMD EPYC™ Processors
- AMD Ryzen™ Series
-
Insufficient checks in System Management Unit (SMU) FeatureConfig may result in reenabling features potentially resulting in denial of resources and/or denial of service.
- AMD EPYC™ Processors
- AMD Ryzen™ Series
-
Insufficient bound checks in the System Management Unit (SMU) may result in a system voltage malfunction that could result in denial of resources and/or possibly denial of service.
- AMD EPYC™ Processors
- AMD Ryzen™ Series
-
Failure to flush the Translation Lookaside Buffer (TLB) of the I/O memory management unit (IOMMU) may lead an IO device to write to memory it should not be able to access, resulting in a potential lo…

-
Failure to assign a new report ID to an imported guest may potentially result in an SEV-SNP guest VM being tricked into trusting a dishonest Migration Agent (MA).
- AMD EPYC™ Processors
-
Insufficient bound checks in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service.
- AMD EPYC™ Processors
- AMD Ryzen™ Series
-
In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a particular sequence of operations that includes creation of a new virtual machine control block (VMCB).
- AMD EPYC™ Processors
-
Insufficient General Purpose IO (GPIO) bounds check in System Management Unit (SMU) may result in access/updates from/to invalid address space that could result in denial of service.
- AMD EPYC™ Processors
- AMD Ryzen™ Series
-
Insufficient bound checks related to PCIE in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service.
- AMD EPYC™ Processors
- AMD Ryzen™ Series
-
A bug in AMD CPU’s core logic may allow for an attacker, using specific code from an unprivileged VM, to trigger a CPU core hang resulting in a potential denial of service.
- AMD EPYC™ Processors
- AMD Ryzen™ Series
-
A TOCTOU race condition in SMU may allow for the caller to obtain and manipulate the address of a message port register which may result in a potential denial of service.
