CVE-2022-48478Network attack vector

Facial recognition service interruption via unchecked memory length

Published May 26, 2023 · Updated Jan 15, 2025

Improper memory-length verification in the facial recognition TA in Huawei HarmonyOS 2.0.0 allows remote attackers to interrupt the service. The trusted application processes facial-recognition memory without verifying its length, so malformed input triggers service exceptions. Network access requires no authentication or user interaction, and the documented consequence is limited to interruption of facial recognition.
