Overview

CVE-2026-19381 is a local privilege escalation vulnerability in Kingston FURY CTRL RGB Control Software 2.0.65.0. The vulnerability resides in the NTIOLib_KSFX.sys driver component and is caused by improper privilege management. This vulnerability requires local access to be exploited, and its successful exploitation allows an attacker to escalate privileges, potentially leading to a complete compromise of the system.

Understanding the Vulnerability / Threat

Root Cause Analysis

The root cause of CVE-2026-19381 is an improper privilege management vulnerability in the NTIOLib_KSFX.sys driver component of Kingston FURY CTRL RGB Control Software 2.0.65.0. This vulnerability falls under CWE-266 and CWE-269 categories, which relate to improper privilege management and privilege escalation, respectively.

Attack Surface & Vector

This vulnerability lives in the software stack at the driver level, specifically in the NTIOLib_KSFX.sys component of Kingston FURY CTRL RGB Control Software. The attack vector is local, meaning an attacker needs to have local access to the system to exploit this vulnerability. The attack complexity is low, and no user interaction is required.

Exploitation Mechanics — Scenario Walkthrough

Scenario: Escalating Privileges in Kingston FURY CTRL RGB Control Software

Initial Position: An attacker has local access to a system with Kingston FURY CTRL RGB Control Software 2.0.65.0 installed. The attacker has limited privileges, such as those of a standard user.

Triggering the Flaw: The attacker manipulates the NTIOLib_KSFX.sys driver component, exploiting the improper privilege management vulnerability. This manipulation could involve crafting specific inputs that are not properly validated or sanitized by the driver, leading to an escalation of privileges.

What Breaks: The security boundary that fails is the driver's privilege management mechanism. Normally, this mechanism should ensure that only authorized actions can be performed with elevated privileges. However, due to the vulnerability, an attacker can bypass these restrictions, leading to an escalation of privileges.

Attacker's Prize: After successfully exploiting the vulnerability, the attacker gains elevated privileges, potentially allowing them to perform actions that were previously restricted. This could include data theft, lateral movement within the network, deployment of malware, or other malicious activities.

Real-World Impact

The real-world impact of CVE-2026-19381 can be significant. An attacker who successfully exploits this vulnerability can escalate privileges, potentially leading to a complete compromise of the system. This could allow for data breaches, malware deployment, or other malicious activities. The affected software is used for managing RGB lighting effects on Kingston FURY gaming peripherals, indicating that systems used in gaming environments or by organizations that utilize Kingston FURY products are at risk.

Detection & Defense

Immediate Mitigations

To mitigate CVE-2026-19381, users of Kingston FURY CTRL RGB Control Software 2.0.65.0 should upgrade to a patched version if available. Additionally, restricting local access to the system and monitoring for suspicious activity related to the Kingston FURY CTRL RGB Control Software can help prevent exploitation.

Detection Strategies

Defenders can detect exploitation attempts by monitoring system logs for unusual activity related to the Kingston FURY CTRL RGB Control Software or the NTIOLib_KSFX.sys driver. Implementing security monitoring tools that can detect anomalies in system behavior or privilege escalation attempts can also be effective.

Long-Term Hardening

To prevent similar vulnerabilities, it's essential to implement defense-in-depth strategies, such as:

  • Regularly updating and patching software
  • Restricting local access to sensitive systems
  • Implementing robust privilege management and access control mechanisms
  • Monitoring system activity for suspicious behavior
