CVE-2025-59466  (opens in a new tab)

How to fix?

Upgrade Debian:unstable nodejs to version 22.22.0+dfsg+~cs22.19.6-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs package and not the nodejs package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

We have identified a bug in Node.js error handling where "Maximum call stack size exceeded" errors become uncatchable when async_hooks.createHook() is enabled. Instead of reaching process.on(&#39;uncaughtException&#39;), the process terminates, making the crash unrecoverable. Applications that rely on AsyncLocalStorage (v22, v20) or async_hooks.createHook() (v24, v22, v20) become vulnerable to denial-of-service crashes triggered by deep recursion under specific conditions.
