CVE-2025-64465

Code execution via out-of-bounds VI parsing

Published Dec 18, 2025 · Updated Dec 18, 2025

Out-of-bounds read in lvre!DataSizeTDR() in NI LabVIEW 2025 Q3 and earlier allows attackers to disclose data or execute code via a crafted VI. The lvre!DataSizeTDR() routine reads beyond the valid buffer boundary while parsing corrupted VI data. Exploitation requires a user to open the specially crafted VI, and the resulting memory corruption runs within the user's LabVIEW process and privileges.
