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

  - Bluetooth: L2CAP: cancel pending_rx_work before taking conn->lock l2cap_conn_del() takes conn->lock and     then calls cancel_work_sync() for pending_rx_work. process_pending_rx() takes the same mutex, so teardown     can deadlock against the worker it is flushing. This issue was found by our static analysis tool and then     manually reviewed against the current tree. The grounded PoC kept the l2cap_conn_ready() ->     queue_work(..., &conn->pending_rx_work) submit path, the l2cap_conn_del() ->     cancel_work_sync(&conn->pending_rx_work) teardown path, and the process_pending_rx() ->     mutex_lock(&conn->lock) worker edge. Lockdep WARNING: possible circular locking dependency detected     process_pending_rx+0x21/0x2a [vuln_msv] l2cap_conn_del.constprop.0+0x3f/0x4e [vuln_msv] *** DEADLOCK ***     Cancel pending_rx_work before taking conn->lock, matching the existing lock-before-drain ordering used for     the two delayed works in the same teardown path. The pending_rx queue is still purged after the work has     been cancelled and conn->lock has been acquired. (CVE-2026-64206)

Note that Nessus relies on the presence of the package as reported by the vendor.
