Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
NVIDIA Bluefield and ConnectX contain a vulnerability in the management interface that could allow a malicious actor with high privilege access to execute arbitrary code.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

NVIDIA Bluefield (DPU) and ConnectX (network adapter) products contain a management interface vulnerability that allows an attacker with high privilege access to execute arbitrary code. This is a privilege escalation issue within the firmware/management plane of the hardware.

MitigationRestrict access to the management interface to trusted administrators only, monitor for compromise of privileged accounts, and apply NVIDIA firmware updates when released. Consider network segmentation of management interfaces.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Bluefield DPU presence
    Check system inventory or run 'lspci | grep -i mellanox' or 'mst status' (Mellanox tools) to list Bluefield devices
    Affected if A Bluefield DPU is present in the environment
  2. Identify ConnectX adapter presence
    Run 'lspci | grep -i connectx' or check NIC inventory for ConnectX network adapters
    Affected if A ConnectX adapter is present in the environment
  3. Check BMC/ICM firmware version
    Access the Bluefield Management Controller (BMC) via IPMI or ELOM and retrieve the firmware version. Use 'ipmitool -I lanplus -H <bmc_ip> -U admin fru' or check via BMC web interface under firmware info
    Affected if The BMC firmware version falls within the affected ranges for CVE-2025-23299 (compare to NVIDIA's published affected versions)
  4. Verify management interface exposure
    Check network configuration to see if the BMC/management interface is accessible from untrusted networks. Review firewall rules and network segmentation around the DPU/adapter management ports
    Affected if The management interface is exposed to networks beyond trusted admin subnets
  5. Audit privileged access to management interface
    Review BMC logs, authentication records, and privileged user activity for the management controller. Check for unexpected privileged accounts or sessions
    Affected if There are privileged accounts or sessions that are unauthorized or unexpected on the management interface

The environment is affected if Bluefield DPUs or ConnectX adapters with management interfaces are present and their firmware version matches the affected ranges, especially if the management interface is accessible beyond trusted administrators.
