CVE-2025-2838

Silicon Labs Gecko OS DNS Response Processing Infinite Loop Denial-of-Service Vulnerability. This vulnerability allows network-adjacent attackers to create a denial-of-service condition on affected installations of Silicon Labs Gecko OS. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of DNS responses. The issue results from a logic error that can lead to an infinite loop. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-23392.
