CVE-2025-2631

Code execution via InitCPUInformation bounds error

Published Apr 9, 2025 · Updated Apr 9, 2025

Out-of-bounds write in InitCPUInformation() in NI LabVIEW 2025 Q1 and earlier allows attackers to execute code via a crafted VI. InitCPUInformation() performs improper bounds checking while processing VI data and writes beyond the intended buffer. Exploitation requires a local user to open the file, and successful memory corruption can disclose information or run attacker-controlled code.
