CVE-2025-2631
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 · uneditedOut of bounds write vulnerability due to improper bounds checking in NI LabVIEW in InitCPUInformation() that may result in information disclosure or arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted VI. This vulnerability affects NI LabVIEW 2025 Q1 and prior versions.
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 · high confidenceOut-of-bounds write vulnerability in NI LabVIEW's InitCPUInformation() function due to improper bounds checking. This allows writing beyond allocated buffer boundaries, potentially leading to information disclosure or arbitrary code execution when a user opens a specially crafted VI file.

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 checksWork through these to decide whether this CVE applies to you.
-
Locate LabVIEW installation directoryCheck common installation paths: C:\Program Files\National Instruments\LabVIEW [version] on Windows, or /Applications/National Instruments/LabVIEW [version] on macOS. Use 'where labview.exe' (Windows) or 'mdfind kMDItemCFBundleIdentifier | grep labview' (macOS) to search.Affected if LabVIEW is found on the system
-
Identify installed LabVIEW versionRight-click the LabVIEW executable (labview.exe or LabVIEW.app), select Properties, then Details. Or run 'labview.exe -?' from command line. On Windows, also check Add/Remove Programs for the version.Affected if Version matches <= 2021, 2022, 2023, 2024, or 2025
-
Verify InitCPUInformation function exists in LabVIEW binariesUse a strings or binary analysis tool on the main LabVIEW executable or core runtime DLLs (search for 'InitCPUInformation' string). On Windows, check niLabVIEW core DLLs in the installation directory.Affected if The InitCPUInformation function string is found in LabVIEW binaries
-
Check for recently opened VI filesReview LabVIEW's recent files list (File > Recent). Check Windows Event Viewer under Application logs for LabVIEW activity, or examine browser/download histories if VI files were downloaded.Affected if Untrusted or unknown VI files were recently opened in LabVIEW
-
Review antivirus logs for LabVIEW-related alertsCheck Windows Event Viewer Security/Application logs, or antivirus quarantine/alert logs for any detections related to LabVIEW VI file processing or the InitCPUInformation function.Affected if Any security alerts mention LabVIEW VI file parsing or the affected function
The environment is affected if LabVIEW is installed with a version matching <= 2021, 2022, 2023, 2024, or 2025, and the InitCPUInformation function is present in the binaries.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate to patched LabVIEW version when available. Do not open VI files from untrusted sources until the patch is applied.
