`CHECK` fail via inputs in `PyFunc`
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
An input `token` that is not a UTF-8 bytestring will trigger a `CHECK` fail in [`tf.raw_ops.PyFunc`](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/lib/core/py_func.cc).
Potential impact
An input token that is not a UTF-8 bytestring will trigger a CHECK fail in tf.rawops.PyFunc.

Matching a version is only one part of assessing exposure. QFinch has not assessed your environment on this public page.
Remediation
Apply the vendor-supported fixed release or mitigation, then verify the affected component is no longer reachable.
- Confirm the affected product and reachable code path exist in your environment.
- Apply the vendor-supported patch or mitigation from the primary advisory.
- Rescan the exact deployed revision and retain verification evidence.
