Sources and claim methodology

Upstream source description

In EmberZNet v9.0.2 and earlier, malformed ClearWeekdaySchedule messages can trigger out-of-bounds writes into Door Lock schedule state. The size and location of this data is limited. These messages must come from a device that has already joined the network. Only devices supporting the Door Lock cluster may be impacted.
