CVSS v3.1 |
| 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 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 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 restriction of operations in the IOMMU could allow a malicious hypervisor to access guest private memory resulting in loss of integrity. |
| 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 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. |
| 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 input validation in system management mode (SMM) could allow a privileged attacker to overwrite stack memory leading to arbitrary code execution. |
| 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. |
| 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 Prevention of Lock Bit Modification in SEV firmware could allow a privileged attacker to downgrade firmware potentially resulting in a loss of 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 |
| 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. |
| 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. |
| 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 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. |
| A bug within some AMD CPUs could allow a local admin-privileged attacker to run a SEV-SNP guest using stale TLB entries, potentially resulting in loss of data 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. |
