When printing a tensor, we get it’s data as a const char*
array (since that’s the underlying storage) and then we typecast it to the element type. However, conversions from char
to bool
are undefined if the char
is not 0
or 1
, so sanitizers/fuzzers will crash.
We have patched the issue in GitHub commit 1be743703279782a357adbf9b77dcb994fe8b508.
The fix will be included in TensorFlow 2.11.0. We will also cherrypick this commit on TensorFlow 2.10.1, TensorFlow 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.
