CVE-2025-2631 National Instruments CVE debrief

Who should care

Organizations using National Instruments LabVIEW, especially teams running version 2025 Q1 or any earlier release. This is most relevant to engineering, test, automation, and industrial environments that process untrusted or externally supplied LabVIEW data.

Technical summary

The advisory describes an out-of-bounds write in LabVIEW while parsing user-supplied data. Affected products are listed as National Instruments LabVIEW: <=2025_Q1. The supplied CVSS 3.1 vector is AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, which means exploitation is rated as requiring local access and user interaction, while the potential impact is high. NI has published remediation guidance and update links in the advisory.

Defensive priority

High. Patch and verify affected LabVIEW deployments promptly, prioritizing systems that process untrusted input or are operationally sensitive.

Recommended defensive actions

• Apply the National Instruments remediation for CVE-2025-2631 using the vendor advisory and update link provided in the source corpus.
• Inventory LabVIEW installations and confirm whether any instance is at version 2025 Q1 or earlier.
• Restrict who can open, import, or otherwise supply data to LabVIEW workflows until updates are applied.
• Review operational procedures for handling externally sourced files or inputs that may be parsed by LabVIEW.
• Track the NI advisory for any follow-up guidance or corrected release information.

Evidence notes

All statements are drawn from the supplied CISA CSAF source item and its listed references. The advisory identifies one affected product entry: National Instruments LabVIEW: <=2025_Q1. The revision history shows the 2025-05-06 update was a typo-fix revision, not a new technical disclosure. No CISA KEV entry was supplied for this CVE.
