Miggo AIMiggo AIMiggo AIRoot Cause AnalysisThe vulnerability stems from the EditDistanceOp's Compute function allocating an output tensor based on output_shape without validating it has >0 elements. The patch adds an explicit check (OP_REQUIRES(ctx, output_elements > 0)) to prevent empty allocations. The original code's lack of this check directly leads to the null dereference when operating on an empty buffer via setZero(). The function's responsibility for buffer allocation and initialization makes it the clear vulnerable entry point.
