CVE-2022-23558Network attack vector

Memory corruption via truncated TFLite allocation size

Published Feb 4, 2022 · Updated Apr 22, 2025

Integer overflow in TFLite array creation in Google TensorFlow allows attackers to corrupt process memory via a crafted TFLite model. TfLiteIntArrayGetSizeInBytes stores the attacker-controlled byte count in an int, allowing truncation before TfLiteIntArrayCreate allocates the array. Processing attacker-controlled model dimensions is required, and the resulting undersized allocation can corrupt or interrupt the hosting process.
