CVE-2026-47145Network attack vector

Process termination via malformed Color Control messages

Published Jun 25, 2026 · Updated Jun 25, 2026

Reachable assertion in Silicon Labs EmberZNet 9.0.2 and earlier allows attackers to terminate the process with Color Control messages. Color Control message handling asserts on malformed hue or saturation values instead of rejecting the input, aborting the process. The sender must already be joined to the Zigbee network, and only devices that support the Color Control cluster are exposed to this service interruption.
