CVE-2024-35250 is a vulnerability identified in the Windows 10 Version 1809 kernel-mode driver, classified under CWE-822 (Untrusted Pointer Dereference). This flaw arises when the kernel-mode driver dereferences pointers that can be influenced by an attacker, leading to memory corruption. Specifically, an attacker with low privileges on a vulnerable system can exploit this flaw to execute arbitrary code in kernel mode, effectively elevating their privileges from a limited user to SYSTEM level. The vulnerability does not require user interaction but does require local access and some level of privileges (PR:L). The CVSS v3.1 score is 7.8, indicating high severity, with impacts rated high on confidentiality, integrity, and availability. The attack vector is local (AV:L), and the attack complexity is low (AC:L), meaning exploitation is feasible if the attacker has local access. No known exploits are currently reported in the wild, and no patches have been released yet, though Microsoft is likely to issue updates given the critical nature of kernel-level vulnerabilities. This vulnerability affects Windows 10 Version 1809 (build 10.0.17763.0), which is an older, out-of-support or limited-support version, commonly still used in some enterprise environments. Exploitation could allow attackers to bypass security controls, install persistent malware, or disrupt system operations by corrupting kernel memory structures.

For European organizations, the impact of CVE-2024-35250 can be significant, especially for those still running Windows 10 Version 1809 in production environments. Successful exploitation can lead to full system compromise, allowing attackers to gain SYSTEM-level privileges, bypass security mechanisms, and execute arbitrary code with kernel-level access. This can result in data breaches, disruption of critical services, and potential lateral movement within networks. Industries such as finance, healthcare, government, and critical infrastructure are particularly at risk due to the sensitive nature of their data and operations. The vulnerability's local attack vector means insider threats or attackers who have gained initial footholds can escalate privileges rapidly. The lack of a patch at the time of disclosure increases the window of exposure. Additionally, legacy systems that cannot be easily upgraded may remain vulnerable for extended periods, increasing risk. The high confidentiality, integrity, and availability impact ratings underscore the potential for severe operational and reputational damage.

1. Upgrade affected systems to a supported and fully patched version of Windows, preferably Windows 10 versions later than 1809 or Windows 11, as these are less likely to be vulnerable. 2. Apply any security updates Microsoft releases addressing CVE-2024-35250 as soon as they become available. 3. Restrict local access to critical systems by enforcing strict access controls, including the use of least privilege principles and strong authentication mechanisms. 4. Monitor system logs and kernel-level events for unusual activity indicative of exploitation attempts, such as unexpected driver loads or privilege escalations. 5. Employ endpoint detection and response (EDR) solutions capable of detecting kernel-level anomalies. 6. Conduct regular security audits and vulnerability assessments focusing on legacy systems. 7. Where upgrading is not immediately feasible, consider isolating vulnerable systems from untrusted users and networks to reduce attack surface. 8. Educate internal staff about the risks of local privilege escalation vulnerabilities and the importance of reporting suspicious activity.
