Root Cause Analysis
The vulnerability stems from the unvalidated direct access to tensor elements in QuantizedReshapeOp's Compute method. The original implementation assumed inputs 2 and 3 (input_min/input_max) were valid scalars but didn't check tensor dimensions/sizes. The patch added explicit validation (OP_REQUIRES) for scalar/vector shape, confirming the vulnerability existed in the pre-patch version of this function.
