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. Join the discussion | GCVE Database | 05/01/2026, 15:16:00 UTC Added: 07/17/2026, 10:27:52 UTC |
