CVE-2025-71006Public exploitNetwork attack vector

Process crash via zero-dimension reshape arithmetic

Published Jan 28, 2026 · Updated Jan 28, 2026

Divide-by-zero in OneFlow 0.9.0 reshape allows attackers to crash a process by supplying a tensor reshape with a zero dimension. The reshape path accepts (-1, 0) and performs dimension-size arithmetic with zero, triggering a floating-point exception instead of rejecting the invalid shape. Execution requires crafted shape values to reach the library through an application, and the resulting exception terminates that process without affecting data confidentiality or integrity.
