CVE-2025-12736 OpenHarmony未初始化资源导致敏感信息泄露漏洞

Identify target device running vulnerable OpenHarmony version 2. Obtain local access with low privileges (PR:L) 3. Trigger vulnerable code path via: - Specific system API calls - Resource allocation manipulation - Specific application interactions 4. Capture leaked data from uninitialized resources 5. Extract sensitive information (credentials, keys, configs) Note: This is a conceptual PoC. Actual exploitation requires deep understanding of OpenHarmony internals and specific vulnerable code paths in the target version. */
