CVE-2025-1055 – K7 Security Anti-Malware IOCTL Elevation of Privilege Vulnerability

CVE ID : CVE-2025-1055

Published : June 11, 2025, 12:15 a.m. | 47 minutes ago

Description : A 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. This flaw stems from missing access control in the driver’s IOCTL handler, enabling unprivileged users to perform privileged actions in kernel space. Successful exploitation can lead to denial of service by disrupting critical services or privileged applications.

Severity: 5.6 | MEDIUM
