Missing validation results in undefined behavior in `SparseTensorDenseAdd

TensorFlow

CVE-2022-29206 · Published May 24, 2022 · updated Jul 13, 2026

Medium5.5
Fix: upgrade to 2.6.4 or later (3 fixed versions below)

Impact

The implementation of [tf.raw_ops.SparseTensorDenseAdd](https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/core/kernels/sparse_tensor_dense_add_op.cc) does not fully validate the input arguments:

```python

import tensorflow as tf

a_indices = tf.constant(0, shape=[17, 2], dtype=tf.int64)

a_values = tf.constant([], shape=[0], dtype=tf.float32)

a_shape = tf.constant([6, 12], shape=[2], dtype=tf.int64)

b = tf.constant(-0.223668531, shape=[6, 12], dtype=tf.float32)

tf.raw_ops.SparseTensorDenseAdd(

a_indices=a_indices, a_values=a_values, a_shape=a_shape, b=b)

`

In this case, a reference gets bound to a nullptr during kernel execution. This is UB.

Patches

We have patched the issue in GitHub commit [11ced8467eccad9c7cb94867708be8fa5c66c730](https://github.com/tensorflow/tensorflow/commit/11ced8467eccad9c7cb94867708be8fa5c66c730).

The fix will be included in TensorFlow 2.9.0. We will also cherrypick this commit on TensorFlow 2.8.1, TensorFlow 2.7.2, and TensorFlow 2.6.4, as these are also affected and still in supported range.
