Code execution via out-of-bounds memory write
Published Aug 2, 2021 · Updated Aug 3, 2024
Out-of-bounds memory access in Huawei EMUI 11.0.0 allows remote attackers to execute malicious code via network input. The affected smartphone component writes beyond a memory buffer boundary when processing untrusted data, but Huawei has not disclosed the component or input format. No privileges or user interaction are required; successful exploitation executes attacker-controlled code on the device.
