Impact
If
tf.tile
is called with a large input argument then the TensorFlow process will crash due to aCHECK
-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 aCHECK
statement. This aborts the process.Patches
We have patched the issue in GitHub commit 9294094df6fea79271778eb7e7ae1bad8b5ef98f (merging #51138).
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.
