Name of the Vulnerable Software and Affected Versions: Silicon Labs (SiLabs) Z-Wave Series 700 and 800 version 7.21.1

Description: The issue is related to insecure permissions in the Silicon Labs Z-Wave Series 700 and 800, which allow attackers to modify the wakeup interval of end devices in the controller's memory. This modification disrupts the device's communications with the controller.

Recommendations: For version 7.21.1, consider restricting access to the controller's memory to prevent unauthorized changes to the wakeup interval until a fix is available. As a temporary workaround, review and secure the permissions settings to minimize the risk of exploitation.
