CWE-59Published: February 18, 2019· Updated: Jun 17, 2026

7.0
CVSS v3.1

Official Description

The LHA.sys driver before 1.1.1811.2101 in LG Device Manager exposes functionality that allows low-privileged users to read and write arbitrary physical memory via specially crafted IOCTL requests and elevate system privileges. This occurs because the device object has an associated symbolic link and an open DACL.

Technical Analysis

CVE-2019-8372 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 7.0.
