Impact
The [
UnbatchGradOp](https://github.com/tensorflow/tensorflow/blob/769eddaf479c8debead9a59a72617d6ed6f0fe10/tensorflow/core/kernels/batch kernels.cc#L891) function takes an argument id that is assumed to be a scalar. A nonscalar id can trigger a CHECK failure and crash the program.python
import numpy as np
import tensorflow as tf
# `id` is not scalar
tf.raw ops.UnbatchGrad(original input= tf.constant([1]),batch index=tf.constant([[0,0,0 ], ], dtype=tf.int64),grad=tf.constant([1,]),id=tf.constant([1,1,], dtype=tf.int64))It also requires its argument
batch index to contain three times the number of elements as indicated in its batch index.dim size(0). An incorrect batch index can trigger a CHECK failure and crash the program.python
import numpy as np
import tensorflow as tf
# batch index's size is not 3
tf.raw ops.UnbatchGrad(original input= tf.constant([1]),batch index=tf.constant([[0,0], ], dtype=tf.int64),grad=tf.constant([1,]),id=tf.constant([1,], dtype=tf.int64))Patches
We have patched the issue in GitHub commit 5f945fc6409a3c1e90d6970c9292f805f6e6ddf2.
The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
