NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-firmware-core package and not the linux-firmware-core package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

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.
