CVE-2022-24937

Device resets via malformed Zigbee packet

Published Nov 14, 2022 · Updated Apr 30, 2025

Buffer-boundary errors in Silicon Labs EmberZNet 1.0.0 through 7.0.0 allow physically proximate attackers to reset Zigbee devices. The stack processes a malformed Zigbee packet without enforcing a memory-buffer boundary, overflows the buffer, and reaches an assertion. No privileges or user interaction are required; the assertion interrupts availability by resetting the affected device, with no reported confidentiality or integrity effect.
