CVE-2023-20584

MediumCVSS 6.0/10Last modified Jun 17, 2026

Description

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.
