CVE-2017-18019 is a high vulnerability (CVSS 7.1) in K7computing Total Security, published January 4, 2018. Public exploit code exists. EPSS puts the chance of exploitation in the next 30 days at 1.24%, the 69th percentile. No source names a fixed version.
In K7 Total Security before 15.1.0.305, user-controlled input to the K7Sentry device is not sufficiently sanitized: the user-controlled input can be used to compare an arbitrary memory address with a fixed value, which in turn can be used to read the contents of arbitrary memory. Similarly, the product crashes upon a \.\K7Sentry DeviceIoControl call with an invalid kernel pointer.
