If you cannot patch yet, consider disabling HTTP/2 server push in the client configuration if possible (e.g., setting client_settings.enable_push to false) to prevent PUSH_PROMISE frames from being accepted.
Description
CVE-2026-48862 is a high-severity vulnerability in the elixir-mint Mint HTTP/2 client library affecting versions 0.2.0 up to but not including 1.9.0. It allows attacker-controlled HTTP/2 servers to exhaust client memory by flooding with PUSH_PROMISE frames. The client accepts server push by default and does not enforce concurrency limits at the time of receiving PUSH_PROMISE frames, leading to unbounded resource allocation until memory exhaustion occurs.
