概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，廠商表示將不會修補。說明
Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。- USB：misc：usbio：修正用戶端拆卸中的中斷連接 UAF usbio_disconnect（） 反向遍歷 usbio->cli_list 並取消初始化每個輔助裝置。auxiliary_device_uninit（） 會刪除裝置參照，並且對於可以執行 usbio_auxdev_release（） 並釋放包含結構usbio_client的未綁定子項。
list_for_each_entry_reverse（） 透過讀取 client->link.prev 在迴圈主體之後前進。如果目前用戶端由 auxiliary_device_uninit（） 釋放，則迭代器會解除參照釋放的記憶體。使用 list_for_each_entry_safe_reverse（），以便在內文刪除最終參照之前快取前一個用戶端。這會保留反向拆卸順序，同時讓下一個迭代器游標獨立於目前用戶端的存留期。驗證重現了此核心報告： 錯誤：KASAN：usbio_disconnect+0x12e/0x150 中的 slab-use-after-free 呼叫追蹤： <TASK> dump_stack_lvl+0x66/0xa0 print_report+0xce/0x630 ？ usbio_disconnect+0x12e/0x150 ？ srso_alias_return_thunk+0x5/0xfbef5 ？ __virt_addr_valid+0x188/0x320 ？ usbio_disconnect+0x12e/0x150 kasan_report+0xe0/0x110 ？ usbio_disconnect+0x12e/0x150 usbio_disconnect+0x12e/0x150 usb_unbind_interface+0xf3/0x400 really_probe+0x316/0x660
