AMD EPYC™ 9004 Series Processors: From CVEorg collector

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.

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

Improper restriction of operations in the IOMMU could allow a malicious hypervisor to access guest private memory resulting in loss of integrity.

Improper Prevention of Lock Bit Modification in SEV firmware could allow a privileged attacker to downgrade firmware potentially resulting in a loss of integrity.
