OpenHarmony — Vulnerabilities & Security Advisories 167

OpenHarmony is an open-source operating system designed for distributed scenarios across smart devices, IoT, and industrial applications. Its architecture emphasizes modularity and scalability, allowing developers to tailor the system for diverse hardware constraints. Historically, the project has faced 167 recorded Common Vulnerabilities and Exposures (CVEs), with recurring issues primarily involving buffer overflows, use-after-free errors, and improper input validation. These flaws often lead to remote code execution or privilege escalation, particularly within the device communication and permission management modules. While no single catastrophic incident has defined its history, the high volume of CVEs highlights challenges in maintaining rigorous security standards across its fragmented ecosystem. The project relies on community-driven patches and formal verification efforts to mitigate risks, though the complexity of its distributed nature continues to present significant attack surface challenges for security researchers and administrators alike.
