Technical details

A segmentation fault (CWE-125) exists in the flow.column_stack component of OneFlow v0.9.0. The vulnerability is triggered when the API attempts to process a list containing a mix of OneFlow tensors and NumPy arrays, leading to a type mismatch or invalid memory access. An attacker can exploit this by providing crafted input that causes the process to crash (core dump), resulting in a denial of service. The issue is confirmed in version 0.9.0 when running on environments such as Ubuntu 22.04 with Python 3.10.

Affected products
