Description
Roger Light reports: If an authenticated client connected with MQTT v5 sent a malformed CONNACK message to the broker a NULL pointer dereference occurred, most likely resulting in a segfault. (Note: a CVE is referenced in the github commit but it appears to be for a python-bleach vulnerability so it is not included here.)
