CVE-2022-23559 Information

Description

Tensorflow is an Open Source Machine Learning Framework. An attacker can craft a TFLite model that would cause an integer overflow in embedding lookup operations. Both embedding_size and lookup_size are products of values provided by the user. Hence a malicious user could trigger overflows in the multiplication. In certain scenarios this can then result in heap OOB read/write. Users are advised to upgrade to a patched version.
