Description
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('uncaughtException')`, 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.

Executive Summary

This vulnerability is a bug in Node.js error handling where "Maximum call stack size exceeded" errors become uncatchable when async_hooks.createHook() is enabled. Instead of the error being caught by process.on('uncaughtException'), the process terminates immediately, causing an unrecoverable crash. Applications using AsyncLocalStorage or async_hooks.createHook() are vulnerable to denial-of-service crashes triggered by deep recursion under specific conditions.

Impact Analysis

The vulnerability can cause denial-of-service crashes in applications that use AsyncLocalStorage or async_hooks.createHook(). When a deep recursion triggers a "Maximum call stack size exceeded" error, the process will terminate without recovery, potentially causing service outages and loss of availability.
