In EmberZNet 9.1.1 and earlier, a malformed GetGroupMembership message can result in an out-of-bounds write leading to a crash.

Only devices supporting the Group Cluster are impacted.

In EmberZNet 9.1.1 and earlier, a malformed Simple_Desc_req response can result in an out-of-bounds write potentially leading to remote code execution. This response must come from a device that has already joined the network, and the attacker must wait for a Simple_Desc_req before the attack can be performed.

In EmberZNet 9.1.1 and earlier, a malformed Publish Billing Period command can result in a recursive function call that will never reach its end condition. These messages must come from a device that has already joined the network. Only devices supporting the Price Cluster are impacted.

In EmberZNet v9.0.2 and earlier, malformed global ZCL messages can trigger out-of-bounds reads in framework parsing logic and terminate the process. These messages must come from a device that has already joined the network.

In EmberZNet v9.0.2 and earlier, a malformed GetProfileResponse message can trigger out-of-bounds reads while iterating interval entries, resulting in process termination. These messages must come from a device that has already joined the network.

In EmberZNet v9.0.2 and earlier, a malformed Level Control Step command can terminate the process through a divide-by-zero fault. This command must come from a device that has already joined the network.

In EmberZNet v9.0.2 and earlier, a malformed Level Control Move command can terminate the process through a divide-by-zero fault. This command must come from a device that has already joined the network.

In EmberZNet v9.0.2 and earlier, malformed ClearWeekdaySchedule messages can trigger out-of-bounds writes into Door Lock schedule state. Only devices that have already joined the network and support the Door Lock cluster may be impacted.

In EmberZNet v9.0.2 and earlier, malformed IAS Zone enrollment messages can trigger an out-of-bounds state-table write and terminate the process. The size and location of this write is limited.
