## Technical details

An integer overflow vulnerability exists in the display driver DIAG escape handler, allowing local unprivileged attackers to cause an out-of-bounds write via a specially crafted escape call. The vulnerability requires local code execution capability (not network-based) and could result in denial of service or arbitrary code execution. A patch is expected from NVIDIA.
