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

  - ngtcp2 is a C implementation of the IETF QUIC protocol. In versions prior to 1.22.1,     ngtcp2_qlog_parameters_set_transport_params() serializes peer transport parameters into a fixed 1024-byte     stack buffer without bounds checking. When qlog is enabled, a remote peer can send sufficiently large     transport parameters during the QUIC handshake to cause writes beyond the buffer boundary, resulting in a     stack buffer overflow. This affects deployments that enable the qlog callback and process untrusted peer     transport parameters. This issue has been fixed in version 1.22.1. If developers are unable to immediately     upgrade, they can disable the qlog on client. (CVE-2026-40170)

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