Lack of data validation - Type confusion In tensorflow

Description

Type confusion leading to CHECK-failure based denial of service in TensorFlow

Impact

The macros that TensorFlow uses for writing assertions (e.g., CHECK_LT, CHECK_GT, etc.) have an incorrect logic when comparing size_t and int values. Due to type conversion rules, several of the macros would trigger incorrectly.

Patches

We have patched the issue in GitHub commit b917181c29b50cb83399ba41f4d938dc369109a1 (merging GitHub PR #55730).

The fix will be included in TensorFlow 2.9.0. We will also cherrypick this commit on TensorFlow 2.8.1, TensorFlow 2.7.2, and TensorFlow 2.6.4, as these are also affected and still in supported range.
