CVE-2026-81581

Name of the Vulnerable Software and Affected Versions WibuKey versions prior to 6.71

Description Improper validation of memory boundaries in the WibuKey64.sys driver allows an attacker to set pointers outside the program scope. This occurs because user input is used without proper sanitization to compute a pointer address, enabling the user to point to any storage location. This typically results in a denial of service, although Remote Code Execution and Privilege Escalation are possible because the driver operates with system privileges.

Recommendations Update WibuKey to version 6.71 or later.
