Feature disruption via out-of-bounds module read
Published Feb 18, 2024 · Updated Mar 13, 2025
Out-of-bounds reads in Huawei HarmonyOS 2.0.0, 3.0.0, 3.1.0, and 4.0.0 and EMUI 12.0.0 and 13.0.0 allow attackers to disrupt features. The smart activity recognition module reads beyond a buffer boundary, but Huawei has not published the input, interface, or function that reaches the faulty read. Published assessments disagree on whether reachability is local or network-based; the confirmed consequence is abnormal feature operation.

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.
- Affected versionversion=2.0.0
- Affected versionversion=3.0.0
- Affected versionversion=3.1.0
- Affected versionversion=4.0.0
