CVE-2026-80894

CVE-2026-80894 affects the Linux kernel iommufd subsystem . The bug is a parameter mismatch in iommufd_hwpt_replace_device(), which passes the new hardware page table (hwpt) to iommufd_auto_response_faults() instead of the old one. Because fault groups are queued under the hwpt active at fault-de...
