CWE-119Published: September 13, 2017· Updated: Jun 17, 2026

7.8
CVSS v3.1

Official Description

In Sophos SurfRight HitmanPro before 3.7.20 Build 286 (included in the HitmanPro.Alert solution and Sophos Clean), a crafted IOCTL with code 0x22E1C0 might lead to kernel data leaks. Because the leak occurs at the driver level, an attacker can use this vulnerability to leak some critical information about the machine such as nt!ExpPoolQuotaCookie.

Technical Analysis

CVE-2017-7441 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
