CVE-2026-80894

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A parameter mismatch exists in the iommufd component. The function iommufd hwpt replace device() incorrectly calls iommufd auto response faults() by passing the new hwpt (hardware page table) instead of the old one, while simultaneously using the old handle of the device domain. Because the group associated with old handle is stored under the old hwpt rather than the new one, this mismatch prevents the correct scanning of the deliver list and response xarray.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
