Floating point exception in SparseDenseCwiseDiv
Impact
The implementation of tf.raw_ops.SparseDenseCwiseDiv is vulnerable to a division by 0 error:
The implementation uses a common class for all binary operations but fails to treat the division by 0 case separately.
Patches
We have patched the issue in GitHub commit d9204be9f49520cdaaeb2541d1dc5187b23f31d9.
The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.
