Data compromise via incomplete GPU permission checks
Published Jul 5, 2023 · Updated Nov 20, 2024
Incorrect authorization in Huawei EMUI 12.0.0 and HarmonyOS 2.0.0 allows remote attackers to read or alter data and interrupt service. The GPU module incompletely verifies read and write permissions, but Huawei has not disclosed the affected interface or the omitted authorization check. Network access without authentication is sufficient, and no user interaction is required; the affected read and write operations remain unspecified.
