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

  - Bluetooth: hci_sync: fix double free in 'hci_discovery_filter_clear()' Function     'hci_discovery_filter_clear()' frees 'uuids' array and then sets it to NULL. There is a tiny chance of the     following race: 'hci_cmd_sync_work()' 'update_passive_scan_sync()' 'hci_update_passive_scan_sync()'     'hci_discovery_filter_clear()' kfree(uuids);
    <-------------------------preempted--------------------------------> 'start_service_discovery()'     'hci_discovery_filter_clear()' kfree(uuids); // DOUBLE FREE     <-------------------------preempted--------------------------------> uuids = NULL; To fix it let's add     locking around 'kfree()' call and NULL pointer assignment. Otherwise the following backtrace fires: [ ]
