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.
