Impact The implementation of `MapStage` is vulnerable a `CHECK`-fail if the key tensor is not a scalar: ```python import tensorflow as tf import numpy as np tf.raw_ops.MapStage( key = tf.constant(value=[4], shape= (1,2), dtype=tf.int64), indices = np.array([[6]]), values = np.array([-60]), dtypes = [tf.int64], capacity=0, memory_limit=0, container='', shared_name='', name=None ) ``` Patches We have patched the issue in GitHub commit f57315566d7094f322b784947093406c2aea0d7d. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.
