CVE-2025-52915 is a high-severity vulnerability rated 7.2/10 on the CVSS scale. K7RKScan.sys 23.0.0.10, part of the K7 Security Anti-Malware suite, allows an admin-privileged user to send crafted IOCTL requests to terminate processes that are protected through a third-party implementation. This is caused by insufficient caller validation in the driver's IOCTL handler, enabling unauthorized processes to perform those actions in kernel space. EPSS estimates a 0.50% chance of exploitation in the next 30 days.
