How to fix?

Upgrade to version 3.0.2 or higher.

Overview is a CSI snapshotter that is part of Kubernetes implementation of Container Storage Interface (CSI).

Affected versions of this package are vulnerable to NULL Pointer Dereference. The snapshot-controller could panic when processing a VolumeSnapshot custom resource when:

  • The VolumeSnapshot referenced a non-existing PersistentVolumeClaim and the VolumeSnapshot did not reference any VolumeSnapshotClass.
  • The snapshot-controller crashes, is automatically restarted by Kubernetes, and processes the same VolumeSnapshot custom resource after the restart, entering an endless crashloop.
