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 (SiLabs) Z-Wave Series 700 and 800, which allows attackers to cause a Denial of Service (DoS) by repeatedly sending crafted packets to the controller.

Recommendations: For version 7.21.1, consider restricting access to the controller to minimize the risk of exploitation until a patch is available. As a temporary workaround, avoid using the vulnerable functionality that allows crafted packets to be sent to the controller.
