CVE-2025-64464

Code execution via crafted VI out-of-bounds read

Published Dec 18, 2025 · Updated Dec 18, 2025

Out-of-bounds read in NI LabVIEW 25.3 and earlier allows attackers to disclose data or execute code through a crafted VI file. lvre!VisaWriteFromFile() reads past a buffer boundary while parsing corrupted VI content; NI has not disclosed the faulty bounds calculation. Execution requires a local user to open the file, after which the process can expose memory or run attacker-controlled code in that user's context.
