Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: USB: gadget: Fix the memory leak in raw_gadget driver Currently, increasing raw_dev->count happens before invoke the raw_queue_event(), if the raw_queue_event() return error, invoke raw_release() will not trigger the dev_free() to be called.
