Last modified
CVE-2023-20584 is a medium-severity vulnerability rated 6/10 on the CVSS scale. 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.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
