Privileged service interruption via out-of-bounds kernel array access
Published May 6, 2025 · Updated May 6, 2025
Out-of-bounds access in the HarmonyOS 5.0.0 kernel module allows local users with high privileges to interrupt device availability. The module reads from or writes to an array outside its allocated bounds, but Huawei has not identified the affected code path, input, or failure mode. Exploitation requires local access, high privileges, and a high-complexity condition; the published impact is limited to availability.

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.
