In the Linux kernel, the following vulnerability has been resolved: usb: cdns3: gadget: fix NULL pointer dereference in ep_queue When the gadget endpoint is disabled or not yet configured, the ep->desc pointer can be NULL. This leads to a NULL pointer dereference when __cdns3_gadget_ep_queue() is called, causing a kernel crash. Add a check to return -ESHUTDOWN if ep->desc is NULL, which is the standard return code for unconfigured endpoints. This prevents potential crashes when ep_queue is called on endpoints that are not ready. A flaw was found in the Linux kernel's cdns3 USB gadget driver. When a gadget endpoint is disabled or not yet configured, a NULL pointer dereference can occur in the `ep_queue` function. This can lead to a kernel crash, resulting in a denial of service (DoS) on the affected system.
