Description

Overflow/crash in tf.tile when tiling tensor is large (CVE-2021-41198)

Details

TensorFlow is an open source platform for machine learning. In affected versions if tf.tile is called with a large input argument then the TensorFlow process will crash due to a CHECK-failure caused by an overflow. The number of elements in the output tensor is too much for the int64_t type and the overflow is detected via a CHECK statement. This aborts the process. 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.

Reason for inclusion in AVID: CVE-2021-41198 describes a vulnerability in TensorFlow (tf.tile) causing a crash due to integer overflow. TensorFlow is a core AI framework used in GP AI systems; the issue affects software components used to build/train/run AI workloads, representing a security vulnerability in the AI software supply chain. The report provides CVE, affected versions, impact and a fix path, giving clear evidence.
