CVE-2025-64464
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 · uneditedThere is an out of bounds read vulnerability in NI LabVIEW in lvre!VisaWriteFromFile() when parsing a corrupted VI file. This vulnerability 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 Q3 (25.3) 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 confidenceAn out-of-bounds read vulnerability exists in NI LabVIEW's lvre!VisaWriteFromFile() function when parsing corrupted VI files. The function fails to properly validate memory boundaries during file parsing, allowing read operations beyond allocated buffers. This can expose sensitive memory contents or potentially enable arbitrary code execution when a user opens a specially crafted malicious 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.
-
Identify installed LabVIEW versionCheck the Windows registry at HKLM\SOFTWARE\National Instruments\LabVIEW\ for the installed version, or look in C:\Program Files\National Instruments\LabVIEW <version>\ for the version folderAffected if The installed version is 2022, 2023, 2024, or 2025
-
Locate LabVIEW installation directoryOpen File Explorer and navigate to C:\Program Files\National Instruments\ or check Program Files (x86)\National Instruments for the LabVIEW folderAffected if LabVIEW version 2022-2025 is present in the installation directory
-
Verify lvre runtime componentsSearch for lvre*.dll files in the LabVIEW installation directory, typically found in the runtime or vi.lib foldersAffected if The lvre DLL files exist in the LabVIEW installation, confirming the vulnerable component is present
-
Assess VI file handling exposureCheck if the LabVIEW environment is configured to automatically open or parse VI files from network shares, email attachments, or download foldersAffected if Users routinely open VI files from untrusted or external sources without prior validation
A user is affected if LabVIEW version 2022, 2023, 2024, or 2025 is installed and the system handles or opens VI files, since the vulnerability triggers when parsing a specially crafted malicious VI file.

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 dataAvoid opening VI files from untrusted or unknown sources. Apply vendor patches when released, maintain up-to-date antivirus scanning, and implement application whitelisting policies for LabVIEW environments.
