CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:N/I:N/A:HA vulnerability in the K7RKScan.sys driver, part of the K7 Security Anti-Malware suite, allows a local low-privilege user to send crafted IOCTL requests to terminate a wide range of processes running with administrative or system-level privileges, with the exception of those inherently protected by the operating system.
