When tf.raw_ops.ResizeNearestNeighborGrad is given a large size input, it overflows.
import tensorflow as tf
align_corners = True
half_pixel_centers = False
grads = tf.constant(1, shape=[1,8,16,3], dtype=tf.float16)
size = tf.constant([1879048192,1879048192], shape=[2], dtype=tf.int32)
tf.raw_ops.ResizeNearestNeighborGrad(grads=grads, size=size, align_corners=align_corners, half_pixel_centers=half_pixel_centers)
We have patched the issue in GitHub commit 00c821af032ba9e5f5fa3fe14690c8d28a657624.
The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.
Please consult our security guide for more information regarding the security model and how to contact us with issues and questions.
