CVE-2025-65886Public exploitNetwork attack vector

Process crash via mismatched eye tensor addition

Published Jan 28, 2026 · Updated Jan 28, 2026

Shape-mismatch handling in OneFlow 0.9.0 allows attackers to crash a process by adding a list-shaped diagonal to an eye tensor. The flow.eye(n) addition path accepts a diagonal operand whose shape does not match the returned matrix and proceeds until a segmentation fault produces a core dump. Reachability requires control of this tensor operation, and successful triggering terminates the hosting OneFlow process.
