CWE-119Published: December 12, 2014· Updated: Jun 17, 2026
7.2
CVSS v3.1
Official Description
Heap-based buffer overflow in the K7FWFilt.sys kernel mode driver (aka K7Firewall Packet Driver) before 14.0.1.16, as used in multiple K7 Computing products, allows local users to execute arbitrary code with kernel privileges via a crafted parameter in a DeviceIoControl API call.
Technical Analysis
CVE-2014-7136 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
