Incomplete validation in `tf.summary.create_file_writer` ### Impact If `tf.summary.create_file_writer` is called with non-scalar arguments code crashes due to a `CHECK`-fail. ```python import tensorflow as tf import numpy as np tf.summary.create_file_writer(logdir='', flush_millis=np.ones((1,2))) ``` ### Patches We have patched the issue in GitHub commit 874bda09e6702cd50bac90b453b50bcc65b2769e https://github.com/tensorflow/tensorflow/commit/874bda09e6702cd50bac90b453b50bcc65b2769e (merging #51715 https://github.com/tensorflow/tensorflow/pull/51715) The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range. ### For more information Please consult our security guide https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md for more information regarding the security model and how to contact us with issues and questions. ### Attribution This vulnerability has been reported externally via a GitHub issue https://github.com/tensorflow/tensorflow/issues/46909.
