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
The NVIDIA NVDebug tool contains a vulnerability that may allow an actor to write files to restricted components. A successful exploit of this vulnerability may lead to information disclosure, denial of service, and data tampering.

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

The NVIDIA NVDebug tool contains a file write vulnerability that allows an attacker to write files to restricted system components. This improper access control flaw can be exploited to achieve information disclosure, denial of service, and data tampering.

MitigationRestrict access to the NVDebug tool to authorized personnel only and monitor for unauthorized use. Apply NVIDIA security updates when available.

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. Verify NVDebug tool is present
    Search for the NVDebug executable on the system using 'where nvdebug' on Windows or 'find / -name nvdebug' on Linux. Common locations include NVIDIA driver installation directories.
    Affected if NVDebug executable is found on the system
  2. Determine installed NVDebug version
    Run 'nvdebug --version' or 'nvdebug -v' to retrieve the version number of the installed NVDebug tool.
    Affected if The version returned is less than 1.7.0 or the command fails to return a version
  3. Check NVDebug binary permissions
    On Linux, run 'ls -la <path_to_nvdebug>' to inspect file permissions. On Windows, right-click the nvdebug.exe file, select Properties, and examine the Users/Groups with Read and Execute permissions.
    Affected if The binary is executable by unprivileged users or groups outside authorized personnel
  4. Inspect NVDebug access control
    Review system access control lists and group memberships to determine which users can execute the NVDebug tool. Check if any unauthorized accounts have access.
    Affected if Non-admin or unauthorized user accounts can execute NVDebug
  5. Audit recent file modifications in system directories
    Review system logs and file system audit trails for any recent writes to restricted directories (system32, /etc, boot) that coincide with NVDebug execution timestamps.
    Affected if Unauthorized file modifications are detected in protected system directories

The system is affected if NVDebug is installed with a version below 1.7.0 and is accessible to unauthorized users.
