Node.js: Hardening Pass Across Streams, Crypto, and Native Bindings
Today's activity is dominated by defensive fixes catching wrong-type errors, out-of-bounds memory access, and state machine race conditions across crypto, streams, and text encoding, alongside new APIs for PKCS12 parsing and QUIC stream flow control.

Good morning, it's September 12th, and this is your Node.js briefing.
The clear signal today: a broad hardening pass across the codebase. Multiple PRs fix cases where wrong input types or edge-case timing could cause crashes, memory corruption, or wrong behavior — not new features, but tightening existing surfaces.
Start with memory safety. PR 65950 fixes an out-of-bounds native write in perf hooks' histogram code, where a malformed offset could corrupt memory during import. PR 65842 corrects error types in the FFI module, so wrong-typed pointers now throw the right error class instead of the wrong one. And two separate PRs —…
Streams got similar attention. Matteo Collina's PR 65986 fixes half-open sockets staying alive after async iteration ends, tied to a socket leak issue. PR 62773 stops a crash when cancelling a web-compatible readable stream mid-flight. And PR 65727 fixes a spec-compliance bug in writable stream's closed promise…
Crypto and TLS saw parallel fixes: PR 65577 corrects CRL bundle loading to read all entries instead of just the first, and PR 65105 from pimterry defers re-entrant calls into the OpenSSL state machine, part of ongoing work tracked in issue 65035.…
