Summary
Undefined behavior when users supply invalid resource handles
Details
Impact
Multiple TensorFlow operations misbehave in eager mode when the resource handle provided to them is invalid:
```python import tensorflow as tf
tf.raw_ops.QueueIsClosedV2(handle=[]) ```
```python import tensorflow as tf
tf.summary.flush(writer=()) ```
In graph mode, it would have been impossible to perform these API calls, but migration to TF 2.x eager mode opened up this vulnerability. If the resource handle is empty, then a reference is bound to a null pointer inside TensorFlow codebase (various codepaths). This is undefined behavior.
Patches
We have patched the issue in GitHub commit a5b89cd68c02329d793356bda85d079e9e69b4e7 and GitHub commit dbdd98c37bc25249e8f288bd30d01e118a7b4498.
The fix will be included in TensorFlow 2.9.0. We will also cherrypick this commit on TensorFlow 2.8.1, TensorFlow 2.7.2, and TensorFlow 2.6.4, as these are also affected and still in supported range.
