CVE-2026-102762: Eclipse Foundation Netx Duo

High severity, CVSS 8.2. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Eclipse Foundation Netx Duo: from 6.0, up to and including 6.5.1.202602
