CVE-2022-31077

Controller crash via nil message pointer dereference

Published Jun 27, 2022 · Updated Apr 23, 2025

Denial of service in KubeEdge before 1.9.3 and 1.10.0 allows remote authenticated users to crash the CloudCore CSI Driver controller. The CSI driver extractMessage function unmarshals a response into a nil model.Message pointer, so JSON null leaves the pointer nil and its subsequent dereference panics. Exploitation requires an authenticated cloud user to launch csidriver and a malicious KubeEdge response; the bounded consequence is controller unavailability.
