CVE-2026-32860
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 a memory corruption vulnerability due to an out-of-bounds write when loading a corrupted LVLIB file in NI LabVIEW. 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 .lvlib file. This vulnerability affects NI LabVIEW 2026 Q1 (26.1.0) 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 write vulnerability exists in NI LabVIEW's LVLIB file loader when parsing a corrupted .lvlib file. This memory corruption can be exploited to achieve information disclosure or arbitrary code execution, requiring the victim to open a specially crafted malicious LVLIB 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 versionOpen LabVIEW and navigate to Help > About LabVIEW, or check the version from the installer/Add or Remove Programs in Windows. For command-line, check the executable properties of LabVIEW.exe.Affected if The installed version is 2022 or earlier, or exactly 2023, 2024, 2025, or 2026.
-
Confirm .lvlib file handling capabilityVerify that LabVIEW is configured to open .lvlib files. Check file associations in Windows (right-click any .lvlib file > Properties > Opens with) or within LabVIEW's Tools > Options > File Preferences.Affected if LabVIEW is associated as the default handler for .lvlib files, which is the default configuration.
-
Audit recent .lvlib file accessCheck Windows Event Viewer under Security/Application logs for recent .lvlib file openings, or use PowerShell: Get-ChildItem -Path $env:USERPROFILE -Filter *.lvlib -Recurse -ErrorAction SilentlyContinue | Select-Object FullName, LastWriteTimeAffected if There are recently opened .lvlib files from untrusted or unknown sources.
-
Review LabVIEW project files for corruption indicatorsOpen any .lvlib files in a hex editor or use LabVIEW's built-in validation (Tools > Advanced > Check Disk) to identify malformed library structures.Affected if Any .lvlib files fail validation checks or show unexpected byte patterns at offset locations related to library metadata.
You are affected if LabVIEW version 2022 or earlier, or any of 2023-2026 is installed AND the system opens or processes .lvlib files, since the vulnerability triggers during parsing of corrupted .lvlib libraries.

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 a patched version of LabVIEW once released; until then, exercise caution and do not open LVLIB files from untrusted sources.
