The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - nfc: nci: Fix race between rfkill and nci_unregister_device(). syzbot reported the splat below [0] without     a repro. It indicates that struct nci_dev.cmd_wq had been destroyed before nci_close_device() was called     via rfkill. nci_dev.cmd_wq is only destroyed in nci_unregister_device(), which (I think) was called from     virtual_ncidev_close() when syzbot close()d an fd of virtual_ncidev. The problem is that     nci_unregister_device() destroys nci_dev.cmd_wq first and then calls nfc_unregister_device(), which     removes the device from rfkill by rfkill_unregister(). So, the device is still visible via rfkill even     after nci_dev.cmd_wq is destroyed. Let's unregister the device from rfkill first in     nci_unregister_device(). Note that we cannot call nfc_unregister_device() before nci_close_device()     because 1) nfc_unregister_device() calls device_del() which frees all memory allocated by devm_kzalloc()     and linked to ndev->conn_info_list 2) nci_rx_work() could try to queue nci_conn_info to     ndev->conn_info_list which could be leaked Thus, nfc_unregister_device() is split into two functions so we     can remove rfkill interfaces only before nci_close_device().
