CVE-2026-32862
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 in ResFileFactory::InitResourceMgr() 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 VI 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 confidenceA memory corruption vulnerability exists in NI LabVIEW's ResFileFactory::InitResourceMgr() function, where an out-of-bounds write occurs. This vulnerability can lead to information disclosure or arbitrary code execution. Successful exploitation requires a user to open 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.
-
Verify LabVIEW is installedCheck for LabVIEW installation directory, typically at C:\Program Files\National Instruments\LabVIEW [version] or C:\Program Files (x86)\National Instruments\LabVIEW [version] on Windows. On macOS, look in /Applications/National Instruments/LabVIEW [version]. On Linux, check /usr/local/natinst/LabVIEW-[version] or /opt/natinst/LabVIEW-[version].Affected if LabVIEW is not installed on the system.
-
Identify installed LabVIEW versionOpen LabVIEW and go to Help > About LabVIEW to see the exact version number. Alternatively, check the installation directory name (e.g., LabVIEW 2023, LabVIEW 2024) or inspect the LabVIEW.ini file in the installation directory for the Version entry.Affected if Unable to determine LabVIEW version or LabVIEW is not present.
-
Compare version against affected rangesMatch your installed version to the affected list: any version 2022 or earlier, or versions 2023, 2024, 2025, or 2026. LabVIEW versions are typically denoted by year (e.g., 2023 corresponds to version 23.0).Affected if Installed version is 2022 or earlier, OR is 2023, 2024, 2025, or 2026.
-
Confirm VI file handling capabilityVerify the LabVIEW installation includes the ability to open and load VI files. This is standard in full LabVIEW installations but may be limited in LabVIEW Run-Time Engine only deployments.Affected if LabVIEW Run-Time Engine is installed without the full development environment and users cannot directly open VI files.
A system is affected if LabVIEW is installed with a version in the 2022 or earlier range, or version 2023 through 2026, and the installation can open VI files.

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 dataOrganizations should avoid opening untrusted VI files and wait for the official vendor patch from NI to address this vulnerability in LabVIEW 2026 Q1 (26.1.0) and prior versions.
