CVE-2025-71001Public exploit

Process crash via mixed tensor-type stacking

Published Jan 28, 2026 · Updated Jan 28, 2026

Denial of service in OneFlow 0.9.0 flow.column_stack allows attackers to crash a process by supplying mixed tensor types. The API attempts to stack a OneFlow tensor with a NumPy array without safely rejecting the type mismatch, causing a segmentation fault and core dump. A caller must cause the host application to pass this mixed list to flow.column_stack; the demonstrated consequence is a process crash.
