In the Linux kernel, the following vulnerability has been resolved: HID: hid-ntrig: fix unable to handle page fault in ntrig_report_version() in ntrig_report_version(), hdev parameter passed from hid_probe(). sending descriptor to /dev/uhid can make hdev->dev.parent->parent to null if hdev->dev.parent->parent is null, usb_dev has invalid address(0xffffffffffffff58) that hid_to_usb_dev(hdev) returned when usb_rcvctrlpipe() use usb_dev,it trigger page fault error for address(0xffffffffffffff58) add null check logic to ntrig_report_version() before calling hid_to_usb_dev()
