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.
