The version of nbdkit installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-47711 advisory.

  - There's a flaw in the nbdkit server when handling responses from its plugins regarding the status of data     blocks. If a client makes a specific request for a very large data range, and a plugin responds with an     even larger single block, the nbdkit server can encounter a critical internal error, leading to a denial-     of-service. (CVE-2025-47711)
