When a handle is opened with a special file attribute value, the drivers improperly initialize FILE_OBJECT->FsContext to a non-pointer magic value. If subsequent operations are not handled by the VB-Audio driver and are forwarded down the audio driver stack (e.g., via PortCls to ks.sys), the invalid FsContext value can be dereferenced, causing a kernel crash (BSoD), typically SYSTEM_SERVICE_EXCEPTION with STATUS_ACCESS_VIOLATION. This flaw allows a local unprivileged user to trigger a denial-of-service on affected Windows systems."
