Code execution via out-of-bounds memory access
Published Feb 25, 2022 · Updated Aug 3, 2024
Out-of-bounds memory access in Huawei HarmonyOS 2.0 and EMUI 10.1.0, 10.1.1, or 11.0.0 allows attackers to execute code via unspecified vectors. Huawei has not published the affected component, boundary calculation, or attacker-controlled input that reaches the invalid access. The exploitation gate remains undisclosed; the established consequence is code execution on an affected phone, with no separately reported confidentiality or availability effect.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
