Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

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

- A flaw was found in libsoup's WebSocket frame processing when handling incoming messages. If a non-default configuration is used where the maximum incoming payload size is unset, the library may read memory outside the intended bounds. This can cause unintended memory exposure or a crash. Applications using libsoup's WebSocket support with this configuration may be impacted. (CVE-2026-0716)

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