What is CVE-2026-47146?

In prior versions of EmberZNet, specifically v9.0.2 and earlier, the system is vulnerable to issues stemming from malformed Color Control messages. These messages, originating from devices that have already joined the network, can cause the application to assert and subsequently terminate the process. Notably, the vulnerability specifically affects devices that support the Color Control cluster. This could pose a significant risk to network stability and operation continuity.

Affected Version(s)
