NVD Description
Note: Versions mentioned in the description apply only to the upstream libertas-sd8787-firmware package and not the libertas-sd8787-firmware package as distributed by RHEL.
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.
