Description OSIDB Bzimport 2026-08-04 01:01:39 UTC 
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**.
