Session operations in eager mode lead to null pointer dereferences

  • Publicada: 14.05.2021
  • Actualizado: 11.10.2026 13:19

Impact

In eager mode (default in TF 2.0 and later), session operations are invalid. However, users could still call the raw ops associated with them and trigger a null pointer dereference:

python
import tensorflow as tf
tf.raw_ops.GetSessionTensor(handle=['\x12\x1a\x07'],dtype=4)
python
import tensorflow as tf
tf.raw_ops.DeleteSessionTensor(handle=['\x12\x1a\x07'])

The implementation dereferences the session state pointer without checking if it is valid:

cc
  OP_REQUIRES_OK(ctx, ctx->session_state()->GetTensor(name, &val));

Thus, in eager mode, ctx->session_state() is nullptr and the call of the member function is undefined behavior.

Patches

We have patched the issue in GitHub commit ff70c47a396ef1e3cb73c90513da4f5cb71bebba.

The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.
