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.
[ 1542.642868][ T534] BUG: KFENCE: use-after-free read in __list_del_entry_valid+0x10/0xd4

Move list_del_init() before cdns3_gadget_ep_free_request() to resolve this
problem.
