CVE-2023-20584: Medium severity amd epyc 8024pn firmware vulnerability

Published Aug 13, 2024
·
Updated

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.
