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

  - Historically, we have been rather lax about malformed framing-related headers in our HTTP/2     implementation, as they cannot interfere with HTTP/2 framing. However, this makes it possible for our     HTTP/2 implementation to forward responses containing such headers to an HTTP/1 client when acting as a     reverse proxy. If the HTTP/1 client also does not behave strictly enough, this can result in response     smuggling. (CVE-2026-78660)

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