The debug print that dumps out newly-dequeued events uses emsg.datalen before that field has been validated, which may lead to an out-of-bounds read. Assume that any properly-formed event message has a valid length field, and move the debug print below the length check.
The length check is a bit redundant as event->datalen is assigned to emsg.datalen upon queuing the event which also does validation. So I would propose to just remove the length check here.
