An exploitable pool corruption vulnerability exists in the 0x8200E804 IOCTL handler functionality of WIBU-SYSTEMS WibuKey.sys Version 6.40 (Build 2400). A specially crafted IRP request can cause a buffer overflow, resulting in kernel memory corruption and, potentially, privilege escalation. An attacker can send an IRP request to trigger this vulnerability.
