CVSS v3.1 |
| 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 potentially overwrite guest memory resulting in loss of guest data integrity. |
| 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. |
| Improper Input Validation in the AMD RAID driver could allow an attacker to point to an arbitrary memory location potentially resulting in privilege escalation and arbitrary code execution. |
| Improper input validation in the System Management Mode (SMM) communications buffer could allow a privileged attacker to perform an out of bounds read or write to a limited section of the Top of Memory Segment (TSEG) memory region, potentially resulting in loss of confidentiality or integrity. |
| 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. |
| Improper enforcement of the LFENCE serialization property may allow an attacker to bypass speculation barriers and potentially disclose sensitive information, potentially resulting in loss of confidentiality. |
| Missing lock bit protection for NBIO registers could allow a local admin-privileged attacker to modify MMIO routing configurations, potentially resulting in loss of SEV-SNP guest integrity. |
| Missing lock bit protection for NBIO registers could allow a local admin-privileged attacker to gain arbitrary System Management Network (SMN) access, potentially resulting in arbitrary code execution in AMD Secure Processor (ASP) and loss of the SEV-SNP guest's confidentiality and integrity. |
| A transient execution vulnerability within AMD CPUs may allow a local user-privileged attacker to leak data via the floating point divisor unit, potentially resulting in loss of confidentiality. |
| Incorrect use of boot service in the AMD Platform Configuration Blob (APCB) SMM driver could allow a privileged attacker with local access (Ring 0) to achieve privilege escalation potentially resulting in arbitrary code execution. |
| A missing lock verification in AMD Secure Processor (ASP) firmware may permit a locally authenticated attacker with administrative privileges to alter MMIO routing on some Zen 5-based products, potentially compromising guest system integrity. |
| Insufficient checks of the RMP on host buffer access in IOMMU may allow an attacker with privileges and a compromised hypervisor to trigger an out of bounds condition without RMP checks, resulting in a potential loss of confidential guest 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. |
| 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 access control in AMD Secure Encrypted Virtualization (SEV) firmware could allow a malicious hypervisor to bypass RMP protections, potentially resulting in a loss of SEV-SNP guest memory integrity. |
| 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. |
| 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. |
| 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 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. |
