+## TFSA-2021-145: Reference binding to nullptr in map operations
+
+### CVE Number
+CVE-2021-37671
+
+### Impact
+An attacker can cause undefined behavior via binding a reference to null pointer
+in `tf.raw_ops.Map*` and `tf.raw_ops.OrderedMap*` operations:
+
+```python
+import tensorflow as tf
+
+tf.raw_ops.MapPeek(
+  key=tf.constant([8],dtype=tf.int64),
+  indices=[],
+  dtypes=[tf.int32],
+  capacity=8,
+  memory_limit=128)
+```
+
+The
+[implementation](https://github.com/tensorflow/tensorflow/blob/460e000de3a83278fb00b61a16d161b1964f15f4/tensorflow/core/kernels/map_stage_op.cc#L222-L248)
+has a check in place to ensure that `indices` is in ascending order, but does
+not check that `indices` is not empty.
+
+### Patches
+We have patched the issue in GitHub commit
+[532f5c5a547126c634fefd43bbad1dc6417678ac](https://github.com/tensorflow/tensorflow/commit/532f5c5a547126c634fefd43bbad1dc6417678ac).
+
+The fix will be included in TensorFlow 2.6.0. We will also cherrypick this
+commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are
+also affected and still in supported range.
