CVE-2025-24988 is a vulnerability classified under CWE-125 (Out-of-bounds Read) found in the Windows USB Video Driver component of Microsoft Windows 10 Version 1507 (build 10.0.10240.0). The flaw allows an attacker with authorized access and physical presence to the affected system to perform an out-of-bounds read operation, which can lead to privilege escalation. This means the attacker can gain higher system privileges than originally granted, potentially allowing them to execute arbitrary code or access sensitive information. The vulnerability does not require user interaction but does require physical access to the device, limiting the attack vector to scenarios where the attacker can interact directly with the hardware. The CVSS 3.1 base score is 6.6, indicating a medium severity level, with the vector string showing physical attack vector (AV:P), low attack complexity (AC:L), low privileges required (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No patches or known exploits are currently available, but the vulnerability has been officially published and reserved by Microsoft. This vulnerability is significant because it targets a core driver component related to USB video devices, which are common in many enterprise and consumer environments, especially in legacy Windows 10 installations that have not been updated to newer versions. The out-of-bounds read could lead to memory corruption or leakage, enabling attackers to bypass security controls and elevate privileges on the system.

For European organizations, the impact of CVE-2025-24988 can be considerable in environments where legacy Windows 10 Version 1507 systems remain in use, particularly in sectors with high physical access risk such as government offices, critical infrastructure, and industrial control systems. The vulnerability allows attackers with physical access to escalate privileges, potentially leading to unauthorized data access, system manipulation, or disruption of services. This could compromise confidentiality, integrity, and availability of sensitive information and critical operations. Although remote exploitation is not possible, the physical access requirement means that organizations with shared workspaces, public terminals, or insufficient physical security controls are at higher risk. The lack of patches increases the window of exposure, and attackers could leverage this vulnerability in targeted attacks or insider threat scenarios. The impact is amplified in environments where legacy systems are integrated into broader networks without proper segmentation, enabling lateral movement after privilege escalation.

To mitigate CVE-2025-24988 effectively, European organizations should prioritize upgrading affected systems from Windows 10 Version 1507 to a supported and patched Windows version, as this legacy build is no longer maintained and lacks security updates. Until upgrades are completed, organizations must enforce strict physical security controls to prevent unauthorized physical access to devices, including secure facilities, locked workstations, and surveillance. Implementing endpoint detection and response (EDR) solutions can help identify unusual privilege escalation attempts or suspicious driver behavior. Network segmentation should be applied to isolate legacy systems from critical infrastructure and sensitive data repositories. Additionally, disabling or restricting USB video devices where not required can reduce the attack surface. Regular audits of device inventory and access logs can help detect potential exploitation attempts. Organizations should also prepare incident response plans that include scenarios involving physical access attacks and privilege escalation. Monitoring for updates from Microsoft and applying patches promptly once available is essential to long-term risk reduction.
