NetX Duo MQTT Client Denial of Service via Malformed PUBLISH Message

Published Sep 29, 2026 CVSS 4.0 · 8.2 High EPSS < 1% KEV · Not listed
Description
The NetX Duo MQTT client leaks the packet carrying a malformed PUBLISH message. Each malformed PUBLISH costs one packet, or one chain of packets, from the network driver's receive pool, and nothing returns it. A peer that can deliver a few dozen such messages exhausts the pool and stops all inbound network traffic on the device until it is rebooted.
