CVSS v3.1 |
| 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. |
| 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 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 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 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 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. |
| 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 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 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 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 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. |
