Background

The package under scrutiny is platform/packages/modules/NeuralNetworks, which is a part of the Android ecosystem. This package provides functionality for neural networks in Android applications. It allows developers to leverage machine learning capabilities for tasks such as image recognition and natural language processing. The vulnerability affects the convertSubgraphFromHAL function in ShimConverter.cpp, specifically the SUBGRAPH parameter. This vulnerability can lead to an out of bounds read, potentially resulting in local information disclosure. Exploitation does not require user interaction.

Vulnerability Detail

The vulnerability arises due to a missing bounds check in the convertSubgraphFromHAL function of ShimConverter.cpp. This allows an attacker to read data beyond the bounds of the SUBGRAPH parameter, leading to potential information disclosure. The impact of this vulnerability is limited to local information disclosure, and it does not grant additional execution privileges. The vulnerability affects versions 12, 12L, and 13 of the platform/packages/modules/NeuralNetworks package. The fix for this vulnerability was implemented in commit 75ee704ed5feafc05440138863c618fddbf3b8be, which was released on January 1, 2024.
