CVE-2026-8554

Description

Type Confusion in ANGLE in Google Chrome on Windows prior to 148.0.7778.168 allowed a remote attacker who had compromised the renderer process to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: High)

    gl.shaderSource(shader, shaderSource);
    gl.compileShader(shader);
    
    // Further specific manipulation of buffers and textures is needed
    // to reach the vulnerable code path in ANGLE.
    console.log('Shader compiled. Exploitation requires specific crafted payload.');
