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

  - nfc: llcp: Fix memleak in nfc_llcp_send_ui_frame(). syzbot reported various memory leaks related to NFC,     struct nfc_llcp_sock, sk_buff, nfc_dev, etc. [0] The leading log hinted that nfc_llcp_send_ui_frame()     failed to allocate skb due to sock_error(sk) being -ENXIO. ENXIO is set by nfc_llcp_socket_release() when     struct nfc_llcp_local is destroyed by local_cleanup(). The problem is that there is no synchronisation     between nfc_llcp_send_ui_frame() and local_cleanup(), and skb could be put into local->tx_queue after it     was purged in local_cleanup(): CPU1 CPU2 ---- ---- nfc_llcp_send_ui_frame() local_cleanup() |- do { ' |-     pdu = nfc_alloc_send_skb(..., &err) | . | |- nfc_llcp_socket_release(local, false, ENXIO); | |-     skb_queue_purge(&local->tx_queue); | | ' | |- skb_queue_tail(&local->tx_queue, pdu); | ... | |- pdu =     nfc_alloc_send_skb(..., &err) | ^._________________________________.' local_cleanup() is called for struct     nfc_llcp_local only after nfc_llcp_remove_local() unlinks it from llcp_devices. If we hold     local->tx_queue.lock then, we can synchronise the thread and nfc_llcp_send_ui_frame(). Let's do that and     check list_empty(&local->list) before queuing skb to local->tx_queue in nfc_llcp_send_ui_frame().
