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.

This patch improves recoverability in one edge case, but it does not remove the broader risk.
Recovery from space exhaustion is unspecified, best‑effort behavior and is not a reliable basis for
availability or security. In availability‑critical paths where recursion depth may be influenced
by untrusted input, prefer input validation and designs that bound or avoid recursion rather than
depending on stack space exhaustion behavior or the lack of tail‑call optimizations in
the runtime/engine. See [this blog post](/blog/vulnerability/january-2026-dos-mitigation-async-hooks)
for details.

Impact:

- This vulnerability affects all users in active release lines: 20.x, 22.x, 24.x, 25.x
