Door Lock state corruption via invalid schedule-table index
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 corrupt Door Lock schedule state. The ClearWeekdaySchedule handler accepts an invalid schedule-table index and writes outside the bounded Door Lock schedule state. Only a device that has joined the Zigbee network can reach the handler, and only devices implementing the Door Lock cluster are affected; the limited write can corrupt state or interrupt operation.
