CVE-2024-38062 is an out-of-bounds read vulnerability classified under CWE-125 found in a kernel-mode driver of Microsoft Windows 10 Version 1809 (build 10.0.17763.0). This vulnerability allows a local attacker with low privileges to read memory outside the intended bounds, which can lead to elevation of privilege by corrupting kernel memory or leaking sensitive information. The flaw arises from insufficient bounds checking in kernel code, enabling attackers to manipulate kernel memory structures, potentially resulting in arbitrary code execution with SYSTEM privileges. The CVSS v3.1 base score is 7.8 (high), reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and requiring only limited privileges and no user interaction. Although no exploits have been reported in the wild yet, the vulnerability poses a significant risk to systems still running this older Windows version, which is no longer supported with security updates. The lack of available patches at the time of publication increases the urgency for mitigation through system upgrades or workarounds. This vulnerability could be leveraged by attackers to bypass security boundaries, gain persistent elevated access, and compromise critical systems.

For European organizations, the impact of CVE-2024-38062 is substantial, especially for those relying on legacy Windows 10 Version 1809 systems in production environments. Successful exploitation can lead to full system compromise, allowing attackers to execute arbitrary code with kernel-level privileges. This threatens the confidentiality of sensitive data, the integrity of system operations, and the availability of critical services. Sectors such as finance, healthcare, government, and critical infrastructure are particularly vulnerable due to their reliance on Windows-based systems and the potential for severe disruption or data breaches. The vulnerability could facilitate lateral movement within networks, enabling attackers to escalate privileges and compromise additional systems. Given the lack of known exploits currently, organizations have a window to proactively mitigate risk before active exploitation emerges. However, the high severity and ease of exploitation by a local attacker necessitate urgent remediation to prevent potential attacks.

European organizations should prioritize upgrading all Windows 10 Version 1809 systems to a supported and fully patched Windows version, such as Windows 10 21H2 or later, or Windows 11. If immediate upgrades are not feasible, organizations should implement strict access controls to limit local user privileges and restrict access to sensitive systems. Employ endpoint detection and response (EDR) solutions to monitor for suspicious kernel-level activity indicative of exploitation attempts. Regularly audit and harden system configurations to minimize attack surfaces, including disabling unnecessary services and drivers. Network segmentation can help contain potential breaches originating from compromised endpoints. Organizations should also stay alert for official Microsoft patches or advisories related to this vulnerability and apply them promptly once available. Additionally, educating users about the risks of local privilege escalation and enforcing the principle of least privilege can reduce the likelihood of successful exploitation.
