CVE-2024-38062 is an out-of-bounds read vulnerability classified under CWE-125 affecting the Windows kernel-mode driver in Windows 10 Version 1809 (build 10.0.17763.0). This vulnerability arises from improper bounds checking in kernel memory operations, allowing an attacker with low privileges (PR:L) to read memory beyond allocated buffers. The flaw can be leveraged to elevate privileges from a limited user context to SYSTEM level, thereby compromising the confidentiality, integrity, and availability of the system. The CVSS v3.1 score of 7.8 reflects a high severity, with an attack vector limited to local access (AV:L), low attack complexity (AC:L), and no user interaction required (UI:N). The scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component without impacting other system components. The vulnerability was reserved in June 2024 and published in July 2024, with no known exploits in the wild at the time of reporting. The absence of patch links suggests that a fix may be pending or in progress. Given the kernel-mode context, exploitation could allow attackers to bypass security controls, install persistent malware, or disrupt system operations. This vulnerability is particularly concerning for environments still running Windows 10 Version 1809, which is an older release with reduced mainstream support, increasing the risk of unpatched systems.

For European organizations, the impact of CVE-2024-38062 is significant, especially for those still operating legacy Windows 10 Version 1809 systems. Successful exploitation can lead to full system compromise, allowing attackers to execute arbitrary code with SYSTEM privileges, disable security mechanisms, and access sensitive data. This can result in data breaches, ransomware deployment, or disruption of critical services. Industries with high regulatory requirements such as finance, healthcare, and government are at heightened risk due to potential data confidentiality and integrity violations. The local attack vector means that insider threats or attackers who gain initial footholds via phishing or physical access could escalate privileges rapidly. The lack of known exploits currently reduces immediate risk, but the vulnerability's nature and severity warrant proactive mitigation. Organizations with delayed patch management or legacy system dependencies in Europe may face increased exposure, potentially affecting operational continuity and compliance with data protection regulations like GDPR.

Until official patches are released, European organizations should implement specific mitigations to reduce risk. First, restrict local access to systems running Windows 10 Version 1809 by enforcing strict access controls, limiting user accounts with local login privileges, and using endpoint protection solutions to detect suspicious local activity. Employ application whitelisting and behavior monitoring to identify attempts to exploit kernel vulnerabilities. Ensure that principle of least privilege is applied rigorously to minimize the attack surface. Network segmentation can help isolate vulnerable systems from critical infrastructure. Organizations should also accelerate plans to upgrade or migrate from Windows 10 Version 1809 to supported Windows versions with active security updates. Monitoring event logs for unusual kernel-mode activity and preparing incident response playbooks for privilege escalation attempts will improve detection and response capabilities. Once Microsoft releases patches, prioritize their deployment in all affected environments. Additionally, educate users about the risks of local exploitation and enforce strong physical security controls to prevent unauthorized access.
