Description

h2 unbounded empty DATA frames

Details
Package h2
Version 0.4.15
URL GHSA-q83h-524g-xf6h
Date 2026年08月17日
Patched versions >=0.4.16

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.

See advisory page for additional details.
