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 DGX Spark GB10 contains a vulnerability in SROOT firmware, where an attacker could cause unexpected memory buffer operations. A successful exploit of this vulnerability might lead to data tampering, denial of service, or escalation of privileges.

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 DGX Spark GB10 contains a vulnerability in SROOT firmware where an attacker could cause unexpected memory buffer operations. Successful exploitation may lead to data tampering, denial of service, or privilege escalation.

MitigationApply NVIDIA-provided firmware update for SROOT when available; prioritize rapid deployment given the high CVSS score and potential for privilege escalation.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 if system is a DGX Spark GB10
    Check the system model or product name via `dmidecode -s system-product-name` or check physical labels on the chassis
    Affected if The system model does not contain 'DGX Spark' or 'GB10' - not affected if it's a different NVIDIA DGX model or non-DGX system
  2. Verify DGX OS is installed
    Check for NVIDIA DGX OS by reviewing `/etc/os-release` or running `cat /etc/dgx-release` if available
    Affected if No DGX OS is present - not in scope for this vulnerability
  3. Check SROOT firmware version
    Use NVIDIA system management tools (such as `nvsm` or vendor-specific firmware querying utilities) to retrieve the SROOT firmware version. Consult NVIDIA documentation for the exact command for your DGX OS version.
    Affected if The SROOT firmware version cannot be determined or is running without a patch - all versions of DGX OS are affected per the advisory; compare against any NVIDIA-provided fixed version when released
  4. Verify SROOT firmware is loaded or active
    Check system firmware status via BMC/IPMI interfaces or NVIDIA management tooling to see if SROOT firmware component is currently active on the system
    Affected if SROOT firmware is present and active on the system - vulnerability is applicable
  5. Review system logs for memory anomalies
    Examine system event logs, BMC logs, or kernel logs for unexpected memory buffer operations, crashes, or privilege escalation indicators that may correlate with exploitation attempts
    Affected if Unusual memory-related events or buffer operation errors are present in logs without known cause

If the system is a NVIDIA DGX Spark GB10 running DGX OS with active SROOT firmware, it is affected since all versions are in the affected product range per the CVE.
