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

  - Bluetooth: L2CAP: Fix deadlock in l2cap_conn_del() l2cap_conn_del() calls cancel_delayed_work_sync() for     both info_timer and id_addr_timer while holding conn->lock. However, the work functions     l2cap_info_timeout() and l2cap_conn_update_id_addr() both acquire conn->lock, creating a potential AB-BA     deadlock if the work is already executing when l2cap_conn_del() takes the lock. Move the work     cancellations before acquiring conn->lock and use disable_delayed_work_sync() to additionally prevent the     works from being rearmed after cancellation, consistent with the pattern used in hci_conn_del().
    (CVE-2026-31499)
