      <div xmlns="http://www.w3.org/1999/xhtml"><p><strong>Affected:</strong> wibu-systems-ag wibukey</p>
<p>In WibuKey for Windows before version 6.71, an untrusted pointer dereference in the WibuKey2_64.sys kernel driver for 64-bit Windows allows an attacker to exploit a write-what-where primitive, enabling local privilege escalation. This can be leveraged to execute arbitrary code, run an administrator shell, or gain full control over the system.</p></div>
