Summary

This vulnerability affects EmberZNet, Silicon Labs' Zigbee networking stack used in embedded wireless devices. A malformed Simple_Desc_req response from a device already on the network can trigger a memory write outside intended bounds, potentially allowing an attacker to execute code remotely.

Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.

Read the original description

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.
