In K7 Ultimate Security versions prior to 17.0.2019, the driver file (K7RKScan.sys - this version 15.1.0.7) allows local users to cause a denial of service (BSOD) or possibly have unspecified other impact because of a null pointer dereference from IOCtl 0x222010 and 0x222014. At the same time, the drive is accessible to all users in the "Everyone" group.
