CVE-2024-38062 is a high-severity vulnerability identified in the Microsoft Windows 10 Version 1809 kernel-mode driver. It is classified as an out-of-bounds read vulnerability (CWE-125), which occurs when the software reads data past the boundary of a buffer. This flaw exists within the Windows kernel, a critical component responsible for managing system resources and hardware interactions. The vulnerability allows an attacker with limited privileges (local access with low privileges) to perform an elevation of privilege attack, potentially gaining higher system privileges without requiring user interaction. The CVSS v3.1 score of 7.8 reflects the significant impact on confidentiality, integrity, and availability, with the attack vector being local (AV:L), low attack complexity (AC:L), and requiring low privileges (PR:L). The vulnerability does not require user interaction (UI:N) and affects Windows 10 Version 1809 (build 10.0.17763.0). Although no known exploits are currently reported in the wild, the vulnerability's nature and impact make it a critical concern for affected systems. Exploiting this vulnerability could allow an attacker to read sensitive kernel memory beyond intended boundaries, potentially leading to information disclosure, system instability, or further exploitation to gain full system control. The lack of a patch link suggests that remediation may still be pending or in progress, emphasizing the need for vigilance and interim mitigations.

For European organizations, this vulnerability poses a significant risk, especially for those still operating legacy systems running Windows 10 Version 1809. Successful exploitation could lead to unauthorized privilege escalation, allowing attackers to bypass security controls and gain administrative access. This could result in data breaches, disruption of critical services, and compromise of sensitive information, including personal data protected under GDPR. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly at risk due to the potential for severe operational and reputational damage. Additionally, the vulnerability could be leveraged as a foothold for lateral movement within networks, increasing the scope of compromise. Given the local attack vector, insider threats or attackers with initial access to endpoints could exploit this flaw to escalate privileges and deepen their control over affected systems.

1. Immediate assessment of the deployment of Windows 10 Version 1809 systems within the organization to identify vulnerable endpoints. 2. Prioritize upgrading or migrating affected systems to a supported and patched Windows version, as Windows 10 Version 1809 is an older release with limited support. 3. Implement strict access controls and monitoring on local user accounts to reduce the risk of privilege escalation from low-privileged users. 4. Employ endpoint detection and response (EDR) solutions capable of detecting anomalous kernel-level activities indicative of exploitation attempts. 5. Restrict physical and remote access to critical systems to trusted personnel only, minimizing the risk of local exploitation. 6. Maintain up-to-date backups and incident response plans to quickly recover from potential compromises. 7. Monitor official Microsoft channels for the release of patches or workarounds addressing CVE-2024-38062 and apply them promptly upon availability.
