Upgrade SLES:16.0.0 nodejs24-docs to version 24.14.1-160000.1.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs24-docs package and not the nodejs24-docs package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

A memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOW_UPDATE frames on stream 0 (connection-level) that cause the flow control window to exceed the maximum value of 2³¹-1. The server correctly sends a GOAWAY frame, but the Http2Session object is never cleaned up.

This vulnerability affects HTTP2 users on Node.js 20, 22, 24 and 25.
