  "title": "usb: cdns3: gadget: Use-after-free during failed initialization and exit of cdnsp gadget",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  usb: cdns3: gadget: Use-after-free during failed initialization and exit of cdnsp gadget  In the __cdnsp_gadget_init() and cdnsp_gadget_exit() functions, the gadget structure (pdev-\u003Egadget) was freed before its endpoints. The endpoints are linked via the ep_list in the gadget structure. Freeing the gadget first leaves dangling pointers in the endpoint list. When the endpoints are subsequently freed, this results in a use-after-free.  Fix: By separating the usb_del_gadget_udc() operation into distinct \u0022del\u0022 and \u0022put\u0022 steps, cdnsp_gadget_free_endpoints() can be executed prior to the final release of the gadget structure with usb_put_gadget().  A patch similar to bb9c74a5bd14(\u0022usb: dwc3: gadget: Free gadget structure  only after freeing endpoints\u0022).",
