In the Linux kernel, the following vulnerability has been resolved: USB: gadget: Fix the memory leak in rawgadget driver Currently, increasing rawdev->count happens before invoke the rawqueueevent(), if the rawqueueevent() return error, invoke rawrelease() will not trigger the devfree() to be called.
