Description Joel Chamberlain 2026-08-10 20:05:06 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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**.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
