  "details": "In the Linux kernel, the following vulnerability has been resolved:  iommufd: Avoid locking internal accesses during unmap  iommufd_access_notify_unmap() skips internal accesses because they do not have an external unmap callback to invoke.  However, the current test calls iommufd_lock_obj() before checking whether the access is internal. If iommufd_lock_obj() succeeds, the loop then sees the internal access and continues, bypassing the matching iommufd_put_object() used by the normal unmap path. This leaks the object reference taken by iommufd_lock_obj().  Check for internal accesses first so skipped entries are never locked.",
