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

  - Bluetooth: ISO: Fix a use-after-free of the hci_conn pointer In iso_sock_rebind_bc(), the bis pointer is     cached, then the socket lock is dropped: bis = iso_pi(sk)->conn->hcon; /* Release the socket before     lookups since that requires hci_dev_lock * which shall not be acquired while holding sock_lock for proper
    * ordering. */ release_sock(sk); hci_dev_lock(bis->hdev); During the unlocked window, could a concurrent     close() destroy the connection and free the bis structure, causing hci_dev_lock(bis->hdev) to access     memory after it is freed, fix this by using the hdev reference which was safely acquired via     iso_conn_get_hdev(). (CVE-2026-53276)

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