Technical details
The vulnerability is an improper input validation flaw in the Wi-Fi beacon frame handler that triggers a divide-by-zero fault in WF200 firmware versions 3.17.0 and earlier. Attack requires only Wi-Fi proximity (adjacent network vector) with no authentication or user interaction. Exploitation results in a fault and denial of service until device reset; a firmware update to 3.18.0 or later fixes the issue.
