Data disclosure and service disruption via unchecked input
Published Feb 6, 2021 · Updated Aug 3, 2024
Out-of-bounds read in Huawei Taurus-AL00A 10.0.0.1(C00E1R1P1) allows local users to expose data and disrupt service through a specific app. An unspecified firmware module accepts an app-delivered message without validating some input before reading beyond its intended bounds. Exploitation requires high privileges and user interaction on the affected smartphone, and the reported result is data exposure or abnormal service rather than code execution.
