CVE-2025-52915
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedK7RKScan.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. Successful exploitation can lead to denial of service by disrupting critical third-party services or applications.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceK7RKScan.sys driver 23.0.0.10 in the K7 Security Anti-Malware suite contains an insufficient caller validation vulnerability in its IOCTL handler. Admin-privileged users can send crafted IOCTL requests to terminate third-party protected processes, allowing unauthorized actions to execute in kernel space. This enables denial of service by disrupting critical services or applications.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the K7RKScan.sys driver fileSearch for K7RKScan.sys in the Windows\System32\drivers directory and any K7 Security product installation folders, or use 'Get-ChildItem -Path C:\ -Recurse -Filter K7RKScan.sys -ErrorAction SilentlyContinue' to find all instancesAffected if The driver file exists on the system, indicating K7 Security Anti-Malware is installed
-
Verify the driver file versionRight-click the K7RKScan.sys file, select Properties, then go to the Details tab to check the Product Version and File Version fields, or run 'powershell (Get-Item "<path_to_driver>").VersionInfo'Affected if The version matches exactly 23.0.0.10 or falls within the affected version range (prior to any vendor fix)
-
Check if the driver is currently loadedOpen an elevated command prompt and run 'sc query K7RKScan' or check Device Manager for hidden/system devices, or use 'driverquery /v | findstr K7RKScan'Affected if The driver shows as RUNNING or LOADED, meaning the vulnerable IOCTL handler is active
-
Confirm administrative access existsRun 'whoami /groups | findstr -i admin' or check if the current user is a member of the Administrators group, as the exploit requires admin privilegesAffected if The current user has administrative rights, enabling the crafted IOCTL requests to be sent
If K7RKScan.sys version 23.0.0.10 is installed and loaded while the current user has administrative privileges, the environment is affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-provided patches for K7RKScan.sys when available. Restrict administrative privileges and monitor for suspicious IOCTL requests targeting protected processes until a fix is deployed.
