CVSS v3.1 |
| Insufficient Granularity of Access Control in SEV firmware can allow a privileged attacker to create a SEV-ES Guest to attack SNP guest, potentially resulting in a loss of confidentiality. |
| 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 Access Control in an on-chip debug interface could allow a privileged attacker to enable a debug interface and potentially compromise data confidentiality or integrity. |
| Improper cleanup in AMD CPU microcode patch loading could allow an attacker with local administrator privilege to load malicious CPU microcode, potentially resulting in loss of integrity of x86 instruction execution. |
| 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. |
| Improper Prevention of Lock Bit Modification in SEV firmware could allow a privileged attacker to downgrade firmware potentially resulting in a loss of integrity. |
| Improper access control within AMD SEV-SNP could allow an admin privileged attacker to write to the RMP during SNP initialization, potentially resulting in a loss of SEV-SNP guest memory 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 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. |
| Improper bound check within AMD CPU microcode can allow a malicious guest to write to host memory, potentially resulting in loss of integrity. |
| Improper Initialization within the AMD Secure Encrypted Virtualization (SEV) firmware can allow an admin privileged attacker to corrupt RMP covered memory, potentially resulting in loss of guest memory integrity |
| 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 restriction of operations in the IOMMU could allow a malicious hypervisor to access guest private memory resulting in loss of 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. |
| 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 input validation in IOMMU could allow a malicious hypervisor to reconfigure IOMMU registers resulting in loss of guest data integrity. |
| 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. |
| 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. |
| 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. |
| Improper isolation of shared resources on a system on a chip by a malicious local attacker with high privileges could potentially lead to a partial loss of integrity. |
