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
