  "title": "usb: gadget: f_ecm: Refactor bind path to use __free()",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  usb: gadget: f_ecm: Refactor bind path to use __free()  After an bind/unbind cycle, the ecm-\u003Enotify_req is left stale. If a subsequent bind fails, the unified error label attempts to free this stale request, leading to a NULL pointer dereference when accessing ep-\u003Eops-\u003Efree_request.  Refactor the error handling in the bind path to use the __free() automatic cleanup mechanism.",
