CVE-2025-41432

// CVE-2025-41432 PoC - OpenHarmony Out-of-Bounds Write // This PoC demonstrates the vulnerability trigger mechanism // Note: Actual exploitation requires specific device and app context // Simulated vulnerable function signature function triggerVulnerability(appId, inputData) { // Vulnerable code pattern (pseudo-code) // The actual vulnerable code exists in OpenHarmony pre-installed apps // where input validation is insufficient // Example trigger scenario: // 1. Identify a pre-installed app with the vulnerability // 2. Prepare malicious input with oversized data // 3. Trigger the vulnerable code path console.log('[PoC] Triggering CVE-2025-41432'); console.log('[PoC] Target App:', appId); console.log('[PoC] Input length:', inputData.length); // Attempt to trigger out-of-bounds write // The actual exploit would require: // - Specific app ID of vulnerable pre-installed app // - Crafted input that exceeds buffer boundaries // - Specific timing and system state return { status: 'vulnerability_triggered', cve_id: 'CVE-2025-41432', affected_versions: 'OpenHarmony <= v5.1.0', attack_vector: 'Local (AV:L)', privileges_required: 'Low (PR:L)', note: 'This is a conceptual PoC.
