Integer Overflow Information Disclosure in NI LabVIEW (CVE‑2026‑18445)
What It Is – NI LabVIEW contains an integer‑overflow flaw in the parsing of VI files. The overflow can be triggered by a malicious file or webpage, allowing a remote attacker to read memory from the LabVIEW process.
Exploitability – Requires user interaction (opening a crafted file or visiting a malicious page). No public exploit code is known, and the CVSS base score is 3.3 (Low‑Moderate).
Affected Products – National Instruments LabVIEW (all supported versions prior to the September 2026 security update).
Why It Matters for Trust & Control Assurance
- Vulnerability Management – The flaw tests the control objective of maintaining an up‑to‑date patch management process; evidence of timely remediation is a key audit artifact.
- Secure Software Development – Lack of proper input validation highlights the need for secure coding standards and regular code‑review evidence.
- Continuous Assurance – Demonstrating that you monitor vendor advisories and can produce remediation proof satisfies multiple framework controls (e.g., NIST CSF Identify and Protect functions).
Recommended Actions
- Deploy the NI LabVIEW security update released September 2026.
- Verify the installed version across all endpoints and update inventory records.
- Conduct a focused code‑review of any custom VI file parsers to ensure proper bounds checking.
- Integrate NI’s advisory feed into your vulnerability‑scanning pipeline for continuous detection.
- Document the remediation steps and retain patch‑deployment logs for audit readiness.
