CVE-2024-4080

Arbitrary code execution via out-of-bounds write

Published Jul 23, 2024 · Updated Sep 29, 2025

Memory corruption in National Instruments LabVIEW 2024 Q1 and earlier allows local users to disclose data or execute code via a crafted VI. The tdcore_24_1.dll library uses an improper length check when processing crafted VI data, permitting an out-of-bounds write. Exploitation requires a user to open the malicious VI, after which successful execution can compromise data or interrupt the application.
