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. |
| 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 bound check within AMD CPU microcode can allow a malicious guest to write to host memory, potentially resulting in loss of integrity. |
| Improper restriction of operations in the IOMMU could allow a malicious hypervisor to access guest private memory resulting in 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. |
| 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 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 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 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. |
