NVD Description

Note: Versions mentioned in the description apply only to the upstream libertas-usb8388-olpc-firmware package and not the libertas-usb8388-olpc-firmware package as distributed by RHEL. See How to fix? for RHEL: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.
