Devices with a Silicon Labs WF200 Wi-Fi chip running firmware 3.17.0 or earlier are affected, per NVD. The CVSS 4.0 vector from Silicon Labs is adjacent-network, no privileges, no user interaction, with impact on availability only. That points to a device in Wi-Fi range being able to cause a fault, with no data impact rated. The sources do not say whether the fault is a crash or a reset. Skip it if you do not ship WF200-based products.
