Process termination via out-of-bounds state-table write
Published Jun 25, 2026 · Updated Jun 25, 2026
Out-of-bounds write in Silicon Labs Zigbee EmberZNet 9.0.2 and earlier allows remote authenticated users to terminate the affected process. Malformed IAS Zone enrollment messages trigger a limited write beyond the state table, but Silicon Labs has not disclosed the responsible function or validation failure. Reachability requires a device already joined to the Zigbee network and an implementation supporting the IAS Zone cluster; the reported consequence is limited to the affected process.
