`h2` 0.4.14 is affected by RUSTSEC-2026-0258 (unbounded empty DATA frames): empty DATA frames can be queued without bound for a stream that is not actively drained, leading to unbounded memory usage or a panic if the length overflows. Low severity, patched in 0.4.16. Lockfile-only; no other package changes.
