Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - nfcnci修正 rfkill 和 nci_unregister_device() 之間的爭用。 syzbot 報告了以下 [0] 的展開而沒有重現。它表示在透過 rfkill 呼叫 nci_close_device() 之前結構體 nci_dev.cmd_wq 已遭到損毀。 nci_dev.cmd_wq 只會在 nci_unregister_device() 中遭到破壞我認為 nci_unregister_device() 是在 syzbot close()d virtual_ncidev 的 fd 時從 virtual_ncidev_close() 呼叫。問題在於 nci_unregister_device() 先損毀 nci_dev.cmd_wq然後再呼叫 nfc_unregister_device()其會從 rfkill by rfkill_unregister() 移除裝置。因此即使 nci_dev.cmd_wq 已損毀仍可透過 rfkill 檢視該裝置。我們先在 nci_unregister_device() 中從 rfkill 取消註冊裝置。請注意我們無法在呼叫 nci_close_device() 之前先呼叫 nfc_unregister_device()因為 1) nfc_unregister_device() 呼叫 device_del()這會釋放 devm_kzalloc() 配置及連結至 ndev->conn_info_list 的所有記憶體 2) nci_rx_work() 可嘗試將 nci_conn_info 排入 ndev 佇列可能洩漏的 ->conn_info_list。因此將 nfc_unregister_device() 分割為兩個函式因此我們只能在執行 nci_close_device() 之前移除 rfkill 介面。 [0]DEBUG_LOCKS_WARN_ON(1) 警告
