CVE-2023-20584 (GCVE-0-2023-20584)

Vulnerability from cvelistv5 – Published: 2024-08-13 16:53 – Updated: 2024-11-05 21:40

Summary

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.

Severity ?

5.3 (Medium)
