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.
