CVE-2024-38185 is a high-severity elevation of privilege vulnerability affecting the Windows 10 Version 1809 kernel-mode driver. The underlying issue is classified under CWE-822, which involves untrusted pointer dereference. This vulnerability arises when the Windows kernel-mode driver dereferences a pointer that can be controlled or influenced by an untrusted source, leading to potential memory corruption. Exploiting this flaw allows an attacker with limited privileges (low-level privileges) to execute arbitrary code in kernel mode, thereby escalating their privileges to SYSTEM level. The CVSS 3.1 base score of 7.8 reflects the significant confidentiality, integrity, and availability impacts possible, with an attack vector requiring local access (AV:L), low attack complexity (AC:L), and low privileges (PR:L), but no user interaction (UI:N). The vulnerability does not require user interaction and can be exploited by a local attacker to gain full control over the affected system. Although no known exploits are currently reported in the wild, the vulnerability's nature and impact make it a critical target for attackers seeking privilege escalation on Windows 10 Version 1809 systems. The affected version is specifically Windows 10 build 17763.0, which corresponds to the 1809 release. No patch links are provided yet, indicating that remediation may still be pending or in progress. The vulnerability was reserved in June 2024 and published in August 2024, indicating recent discovery and disclosure.

For European organizations, this vulnerability poses a significant risk, especially for those still operating legacy systems running Windows 10 Version 1809. Successful exploitation could allow attackers to bypass security controls, gain SYSTEM-level privileges, and execute arbitrary code with full kernel access. This could lead to complete system compromise, data theft, disruption of critical services, and deployment of persistent malware such as ransomware or advanced persistent threats (APTs). The confidentiality, integrity, and availability of sensitive data and critical infrastructure could be severely impacted. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly at risk due to the potential for high-impact breaches and operational disruptions. The local attack vector means that attackers would need initial access, which could be achieved through phishing, compromised credentials, or insider threats. Given the lack of known exploits in the wild, proactive mitigation is essential to prevent future exploitation, especially as attackers often weaponize such vulnerabilities rapidly once public disclosure occurs.

European organizations should prioritize the following specific mitigation steps: 1) Identify and inventory all systems running Windows 10 Version 1809 (build 17763.0) to understand exposure. 2) Apply any available security updates or patches from Microsoft as soon as they are released; monitor Microsoft Security Update Guide and related advisories closely. 3) If patches are not yet available, consider temporary mitigations such as restricting local user access to trusted personnel only and enforcing strict access controls to limit the ability of low-privileged users to execute arbitrary code. 4) Employ endpoint detection and response (EDR) solutions capable of monitoring kernel-mode activities and detecting suspicious behavior indicative of privilege escalation attempts. 5) Harden systems by disabling unnecessary services and drivers that could be leveraged in exploitation. 6) Conduct regular security awareness training to reduce the risk of initial access vectors like phishing. 7) Implement network segmentation and least privilege principles to contain potential compromises. 8) Prepare incident response plans specifically addressing kernel-level compromises to enable rapid containment and recovery.
