Local memory corruption via kernel over-read
Published Oct 14, 2022 · Updated May 14, 2025
Out-of-bounds reads in the kernel module of Huawei HarmonyOS 2.0 and 2.1 and EMUI 11.0.1 and 12.0.0 allow local users to overwrite memory. Huawei discloses that the module reads beyond an intended memory boundary but does not identify the affected function, accepted input, or failed bounds check. Exploitation requires local low-privileged access; public materials identify memory corruption but no specific crash, disclosure path, or privilege gain.

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
- Affected versionversion=2.1
