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 [ 1542.642868][ T534] [ 1542.653162][ T534] Use-after-free read at 0x000000009ed0ba99 (in kfence-#3): [ 1542.660311][ T534] __list_del_entry_valid+0x10/0xd4 [ 1542.665375][ T534] cdns3_gadget_ep_disable+0x1f8/0x388 [cdns3] [ 1542.671571][ T534] usb_ep_disable+0x44/0xe4 [ 1542.675948][ T534] ffs_func_eps_disable+0x64/0xc8 [ 1542.680839][ T534] ffs_func_set_alt+0x74/0x368 [ 1542.685478][ T534] ffs_func_disable+0x18/0x28 Move list_del_init() before cdns3_gadget_ep_free_request() to resolve this problem.
