CVE-2024-26749

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

usb: cdns3: fixed memory use after free at cdns3_gadget_ep_disable()

...
cdns3_gadget_ep_free_request(&priv_ep->endpoint, &priv_req->request);
list_del_init(&priv_req->list);
...

'priv_req' actually free at cdns3_gadget_ep_free_request(). But
list_del_init() use priv_req->list after it.
