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
A DLL hijacking vulnerability in Vivado could allow a local attacker to achieve privilege escalation, potentially resulting in arbitrary code execution.

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

A DLL hijacking vulnerability in Xilinx Vivado allows a local attacker to load a malicious DLL in place of a legitimate one the application expects, potentially achieving privilege escalation and arbitrary code execution by injecting code that runs with the victim's privileges.

MitigationApply vendor-provided patches when available; in the interim, ensure the Vivado application runs from directories with strict access controls and remove any untrusted DLLs from searchable paths.

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 Xilinx Vivado is installed
    Search for the Vivado installation directory - common locations include C:\Xilinx\Vivado or C:\Program Files\Xilinx\Vivado on Windows, or /opt/Xilinx/Vivado on Linux. Check for the presence of Vivado executable files (vivado.exe on Windows, vivado on Linux).
    Affected if Vivado is found installed on the system
  2. Determine the installed Vivado version
    Run 'vivado -version' from the Vivado installation bin directory, or check the version information of the vivado.exe file via file properties. Compare the version number against any vendor-provided version guidance.
    Affected if The installed version is older than the patched version provided by Xilinx
  3. Inspect the Vivado installation directory for suspicious DLLs
    List all DLL files in the Vivado bin and lib directories. Look for unknown or recently added DLL files that are not part of the standard Vivado installation. Check for DLLs with unusual names or those matching common DLL hijacking targets (e.g., user32.dll, kernel32.dll placed in the application directory).
    Affected if Unexpected or unauthorized DLL files are present in the Vivado bin or lib directories
  4. Check DLL search path configuration
    Review the system PATH environment variable and any Vivado-specific PATH settings. Check if the Vivado installation directory is listed before system directories in PATH, which could allow local DLL loading. Use 'echo %PATH%' on Windows or 'echo $PATH' on Linux to review.
    Affected if Vivado bin directory appears earlier in PATH than system directories, allowing local DLL loading
  5. Verify file permissions on the Vivado installation directory
    Check that the Vivado installation directory and its subdirectories have restrictive permissions, allowing only authorized users write access. On Windows, right-click the directory > Properties > Security tab. On Linux, use 'ls -la /path/to/Vivado' to review owner and permissions.
    Affected if Non-administrator users have write access to the Vivado installation directory, allowing them to place malicious DLLs

A user is affected if Xilinx Vivado is installed and the application directory or its directories in PATH are writable by untrusted users, enabling placement of malicious DLLs for hijacking.
