DescriptionIn the Linux kernel, the following vulnerability has been resolved: usb: xusbatm: don't rely on id table pointer arithmetic The current code is broken when dynamic ID is involved; in such cases usb_device_id parameter of probe lives on the heap and the pointer arithmetic will get an index that is wildly out of bound. xusbatm initialize the USB device IDs dynamically so it can just use driver_info too. Even with conversion, xusbatm still cannot support dynamic IDs, so also set no_dynamic_id.
