Security Vulnerabilities

h2: h2 unbounded empty DATA frames

RUSTSEC-2026-0258

The h2 crate, used internally by hyper, had a flaw that would accept and queue empty DATA frames without limit. If streams were not actively drained, this could lead to unbounded memory usage, or a panic if the length overflows.

Low severity.

Patched in v0.4.16.
