NVD Description

Note: Versions mentioned in the description apply only to the upstream hey package and not the hey package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
