CVSS v3.1 |
| Improper initialization of CPU cache memory could allow a privileged attacker with hypervisor access to overwrite SEV-SNP guest memory resulting in loss of data integrity. |
| Improper input validation in IOMMU could allow a malicious hypervisor to reconfigure IOMMU registers resulting in loss of guest data integrity. |
| Improper handling of overlap between the segmented reverse map table (RMP) and system management mode (SMM) memory could allow a privileged attacker corrupt or partially infer SMM memory resulting in loss of integrity or confidentiality. |
| Improper key usage control in AMD Secure Processor
(ASP) may allow an attacker with local access who has gained arbitrary code
execution privilege in ASP to
extract ASP cryptographic keys, potentially resulting in loss of
confidentiality and integrity. |
| Insufficient or Incomplete Data Removal in Hardware Component in SEV firmware doesn't fully flush IOMMU. This can potentially lead to a loss of confidentiality and integrity in guest memory. |
| Improper bound check within AMD CPU microcode can allow a malicious guest to write to host memory, potentially resulting in loss of integrity. |
| 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. |
| Improper input validation in the SMM communications buffer could allow a privileged attacker to perform an out of bounds read or write to SMRAM potentially resulting in loss of confidentiality or integrity. |
| Missing Checks in certain functions related to RMP initialization can allow a local admin privileged attacker to cause misidentification of I/O memory, potentially resulting in a loss of guest memory integrity |
| Improper handling of direct memory writes in the input-output memory management unit could allow a malicious guest virtual machine (VM) to flood a host with writes, potentially causing a fatal machine check error resulting in denial of service. |
| Improper handling of error condition during host-induced faults can allow a local high-privileged attack to selectively drop guest DMA writes, potentially resulting in a loss of SEV-SNP guest memory integrity |
| 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. |
| Write what were condition within AMD CPUs may allow an admin-privileged attacker to modify the configuration of the CPU pipeline potentially resulting in the corruption of the stack pointer inside an SEV-SNP guest. |
| 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. |
| Improper restriction of operations in the IOMMU could allow a malicious hypervisor to access guest private memory resulting in loss of integrity. |
| Improper restriction of operations within the bounds of a memory buffer in PCIe® Link could allow an attacker with access to a guest virtual machine to potentially perform a denial of service attack against the host resulting in loss of availability. |
| A use after free in the SEV firmware could allow a malicous hypervisor to activate a migrated guest with the SINGLE_SOCKET policy on a different socket than the migration agent potentially resulting in loss of integrity. |
| When SMT is enabled, certain AMD processors may speculatively execute instructions using a target
from the sibling thread after an SMT mode switch potentially resulting in information disclosure. |
| Failure to validate inputs in SMM may allow an attacker to create a mishandled error leaving the DRTM UApp in a partially initialized state potentially resulting in loss of memory integrity. |
| Improper initialization of variables in the DXE driver may allow a privileged user to leak sensitive information via local access. |
