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.

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.

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 input validation in IOMMU could allow a malicious hypervisor to reconfigure IOMMU registers resulting in loss of guest 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.
