Description
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.
