  "details": "In the Linux kernel, the following vulnerability has been resolved:  iommufd: Fix wrong hwpt passed to iommufd_auto_response_faults on replace  iommufd_hwpt_replace_device() calls:  \tiommufd_auto_response_faults(hwpt, old_handle);  passing the *new* hwpt together with the handle of the device's *old* domain. This should be a parameter mismatch:  1. Semantically, iommufd_auto_response_faults(x, handle) scans    x-\u003efault's deliver list and response xarray for groups matching    \"handle\". A group is queued under the hwpt that was attached at    fault-delivery time. old_handle is fetched *before* the domain switch,    so its group lives on old-\u003efault, not on the new hwpt-\u003efault.  2. Historically, the first argument was \"old\". The routine was    introduced by commit b7d8833677ba (\"iommufd: Fault-capable hwpt    attach/detach/replace\") as __fault_domain_replace_dev() in    fault.c, correctly calling iommufd_auto_response_faults(old, curr).    Commit fb21b1568ada (\"iommufd: Make attach_handle generic than    fault specific\") moved this into iommufd_hwpt_replace_device() in    device.c and swapped it to \"hwpt\". This should be a refactor regression,    not an intentional change.  Fix this by passing \"old\" instead.",
