TFSA-2022-088: CHECK failure in TensorListReserve via missing validation
CVE Number
CVE-2022-35960
Impact
In core/kernels/list_kernels.cc's TensorListReserve, num_elements is assumed to be a tensor of size 1. When a num_elements of more than 1 element is provided, then tf.raw_ops.TensorListReserve fails the CHECK_EQ in CheckIsAlignedAndSingleElement.
import tensorflow as tf
tf.raw_ops.TensorListReserve(element_shape=(1,1), num_elements=tf.constant([1,1], dtype=tf.int32), element_dtype=tf.int8)
Patches
We have patched the issue in GitHub commit xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.
The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
