The driver allocates GPIO registers using incorrect bounds, leading to access of non-allocated memory addresses. This could cause kernel memory corruption or crashes during display initialization." ],
  "statement" : "Exploitation requires an AMD GPU with the affected display controller code path. The out-of-bounds access occurs during driver initialization rather than through user-controlled input, limiting attack surface.",
