CVE:CVE-2023-20584 vulnerable 2026-06-08 05:52:45.223913 Details available
MEDIUM (5.3)
IOMMU improperly handles certain special address ranges with invalid device table entries (DTEs), which may allow an attacker with privileges and a compromised Hypervisor to induce DTE faults to bypass RMP checks in SEV-SNP, potentially leading to a loss of guest integrity.
