NVD Description

Note: Versions mentioned in the description apply only to the upstream npm package and not the npm package as distributed by Centos. See How to fix? for Centos:8 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.
