CVE-2022-31076

Authenticated service crash via nil JSON message

Published Jun 27, 2022 · Updated Apr 22, 2025

Denial of service in KubeEdge before 1.9.3 and 1.10.0 allows remote authenticated users to crash CloudCore via a local UDS message. The UDS Server's ExtractMessage function unmarshals JSON into a pointer that can remain nil, then returns it for subsequent dereference. The path is reachable only from the cloud-side CSI Driver over the local host network when CloudHub's unixsocket setting is enabled.
