CVE-2025-59192 is a buffer over-read vulnerability classified under CWE-126 found in the Storport.sys driver of Microsoft Windows 10 Version 1507 (build 10.0.10240.0). The Storport driver is responsible for storage port operations, and improper handling of memory boundaries allows an attacker with local authorized access to read beyond allocated buffers. This memory mismanagement can lead to elevation of privileges by corrupting or leaking sensitive kernel memory, enabling attackers to execute code with higher privileges or cause system instability. The vulnerability requires the attacker to have some level of local privileges (PR:L) but does not require user interaction (UI:N). The CVSS v3.1 base score is 7.8, indicating high severity with high impact on confidentiality, integrity, and availability. The attack vector is local, and the attack complexity is low, meaning exploitation is feasible but limited to local users. No public exploits or patches have been reported at the time of publication, but the vulnerability poses a significant risk to systems still running this legacy Windows 10 version. The flaw highlights the risks of outdated operating systems and the importance of timely patching or upgrading to supported versions.

The vulnerability allows a local attacker to elevate privileges, potentially gaining SYSTEM-level access on affected Windows 10 Version 1507 machines. This can lead to full compromise of the system, including unauthorized access to sensitive data, installation of persistent malware, and disruption of system operations. The buffer over-read can also cause system crashes or instability, impacting availability. Organizations relying on legacy Windows 10 installations, particularly in environments where local user access is possible, face increased risk of insider threats or malware leveraging this flaw for privilege escalation. The impact extends to confidentiality, integrity, and availability, making it a critical concern for enterprise environments, government agencies, and critical infrastructure sectors still using this outdated OS version.

1. Upgrade affected systems from Windows 10 Version 1507 (build 10.0.10240.0) to a supported and fully patched Windows version to eliminate the vulnerability. 2. If upgrading immediately is not feasible, restrict local user access and enforce the principle of least privilege to minimize the risk of exploitation. 3. Monitor system logs and security alerts for unusual activity indicative of privilege escalation attempts. 4. Employ endpoint detection and response (EDR) solutions capable of detecting anomalous behavior related to kernel driver exploitation. 5. Once Microsoft releases an official patch, prioritize its deployment across all affected systems. 6. Conduct regular vulnerability assessments and penetration testing focusing on legacy systems to identify and remediate similar risks. 7. Educate system administrators and users about the risks of running unsupported OS versions and the importance of timely updates.
