*   Fixes a heap OOB read in `tf.ragged.cross`
    ([CVE-2021-41212](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-41212))
*   Fixes a heap OOB in shape inference for `QuantizeV2`
    ([CVE-2021-41211](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-41211))
*   Fixes a heap OOB read in all `tf.raw_ops.QuantizeAndDequantizeV*` ops

## Pull Request Checklist

Before sending your pull requests, make sure you do the following:

-   Read the [contributing guidelines](CONTRIBUTING.md).
-   Read the [Code of Conduct](CODE_OF_CONDUCT.md).
-   Ensure you have signed the
    [Contributor License Agreement (CLA)](https://cla.developers.google.com/).
-   Check if your changes are consistent with the

// maximum number of in flight async nodes. Enqueuing of additional async ops
// after the limit is reached blocks until some inflight nodes finishes.
// The effect is bounding the memory held by inflight TensorHandles that are
// referenced by the inflight nodes.
// A recommended value has not been established.
// A value of 0 removes the limit, which is the behavior of TensorFlow 2.11.
