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 · moderate confidence

A memory leak vulnerability exists in K7TSMngr.exe, a component of K7Computing K7AntiVirus Premium version 15.1.0.53. The vulnerability allows an attacker to cause the process to consume excessive memory over time, potentially leading to denial of service or memory exhaustion on the affected system.

MitigationApply the vendor-supplied patch or update K7AntiVirus to a version that addresses this memory leak vulnerability. If no patch is available, consider disabling or restricting the affected K7TSMngr.exe component until a fix is released.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify K7Computing security software installation
    Check for K7Computing products in the system: Look in 'C:\Program Files\K7 Computing' or 'C:\Program Files (x86)\K7 Computing' directories, or query the Windows Registry under HKLM\SOFTWARE\K7 Computing or HKLM\SOFTWARE\Wow6432Node\K7 Computing
    Affected if No K7Computing software is found on the system, then this CVE does not apply.
  2. Determine installed K7 product version
    Open Windows Registry and navigate to HKLM\SOFTWARE\K7 Computing\Product\Version (or the Wow6432Node equivalent) to read the installed version number, or right-click on the main executable in the K7 installation folder and view Properties > Details for the File Version
    Affected if The installed version falls below 16.0.0001 for AntiVirus/Total/Ultimate Security, or below 14.2.0001 for Enterprise Security.
  3. Locate and verify the vulnerable K7TSMngr.exe component
    Search for K7TSMngr.exe in the K7 installation directory (typically C:\Program Files\K7 Computing\K7TSMngr.exe or C:\Program Files (x86)\K7 Computing\K7TSMngr.exe). Check if the file exists on the system
    Affected if K7TSMngr.exe is not present, the memory leak vulnerability cannot be triggered.
  4. Check if K7TSMngr.exe process is running
    Open Task Manager, go to the Processes tab, and look for K7TSMngr.exe, or run 'tasklist /FI "IMAGENAME eq K7TSMngr.exe"' in Command Prompt
    Affected if The process is actively running, which enables the memory leak condition to manifest over time.

A system is affected if it has any K7Computing security product version below 16.0.0001 (or below 14.2.0001 for Enterprise Security) with the K7TSMngr.exe component present and running.
