Linux Distros Unpatched Vulnerability : CVE-2026-44579

high Nessus Plugin ID 318350

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.

- Next.js is a React framework for building full-stack web applications. From to before 15.5.16 and 16.2.5, applications using Partial Prerendering through the Cache Components feature can be vulnerable to connection exhaustion through crafted POST requests to a server action. In affected configurations, a malicious request can trigger a request-body handling deadlock that leaves connections open for an extended period, consuming file descriptors and server capacity until legitimate users are denied service.
This vulnerability is fixed in 15.5.16 and 16.2.5. (CVE-2026-44579)

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

Solution

There is no known solution at this time.
