CVE-2024-3051Network attack vector

End-device denial via malformed reset commands

Published Apr 26, 2024 · Updated Sep 27, 2024

Denial of service in Silicon Labs Z/IP Gateway SDK 7.18.03 and earlier allows remote attackers to interrupt end-device communications. A malformed Device Reset Locally command makes the gateway stop acknowledging every frame sent by the targeted end device. Unauthenticated network reachability to the gateway is sufficient; the effect is a temporary, targeted communication interruption.
