NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs:24/nodejs-libs package and not the nodejs:24/nodejs-libs package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

A flaw in Node.js allows a spoofed TypedArray byteLength to trigger a reachable assertion in the synchronous node:zlib APIs, causing the entire process to crash. All 11 synchronous zlib functions are affected.

Repeated exploitation of this condition can result in a denial of service.

This vulnerability affects Node.js 22.x, 24.x, and 26.x.
