What is CVE-2018-5220?

In K7 Antivirus version 15.1.0306, the K7Sentry.sys driver does not properly validate input values from IOCtl 0x95002610. This oversight can allow local users to trigger a denial of service condition, potentially leading to a Blue Screen of Death (BSOD) or other unspecified impacts. Because of this vulnerability, unauthorized users could exploit the system’s response to manipulated input, thereby compromising system stability.
