Local service interruption via runtime buffer overflow
Published Mar 4, 2025 · Updated Mar 11, 2025
Buffer overflow in ArkCompiler eTS Runtime in OpenHarmony 4.1.0 through 5.0.2 allows local users to interrupt service. The CNA maps the flaw to an unchecked buffer copy but has not disclosed the affected function, input path, or buffer operation within the runtime. Exploitation requires low-privileged local access and no user interaction, and the documented consequence is limited to availability loss.

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.
