  <description>
    <p>A vulnerability has been found in the way NVIDIA drivers handle
      read/write access to GPU device nodes, allowing access to arbitrary
      system memory locations.
    </p>
    
    <p>NOTE: Exposure to this vulnerability is reduced in Gentoo due to 660
      permissions being used on the GPU device nodes by default.
