mod_http2 reports:

The Apache HTTPD web server (from 2.4.17-2.4.23) did not apply limitations on request headers correctly when experimental module for the HTTP/2 protocol is used to access a resource.

The net result is that a the server allocates too much memory instead of denying the request. This can lead to memory exhaustion of the server by a properly crafted request.
