CVE-2025-64468

Code execution via corrupted VI use-after-free

Published Dec 18, 2025 · Updated Dec 18, 2025

Use-after-free in NI LabVIEW 25.3.2 and earlier allows context-dependent attackers to execute code through a corrupted VI file. The sentry!sentry_span_set_data() routine accesses freed memory while LabVIEW parses corrupted VI contents. Execution requires a user to open the crafted file; successful exploitation can also disclose process memory.
