Description

CHECK fail via inputs in SparseFillEmptyRowsGrad

Impact

If SparseFillEmptyRowsGrad is given empty inputs, TensorFlow will crash.

import tensorflow as tf
tf.raw_ops.SparseFillEmptyRowsGrad(
    reverse_index_map=[], grad_values=[], name=None
)

Patches

We have patched the issue in GitHub commit af4a6a3c8b95022c351edae94560acc61253a1b8.

The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.
