CVE-2025-32719 is a medium-severity vulnerability identified in Microsoft Windows 10 Version 1809 (build 10.0.17763.0). It is classified as an out-of-bounds read (CWE-125) within the Windows Storage Management Provider component. This vulnerability allows an authorized attacker with local access and low privileges (PR:L) to read memory beyond the intended buffer boundaries, potentially disclosing sensitive information stored in adjacent memory regions. The vulnerability does not require user interaction (UI:N) and has a low attack complexity (AC:L), but it is limited to local attack vectors (AV:L), meaning the attacker must have local access to the affected system. The scope of the vulnerability is unchanged (S:U), and the impact is limited to confidentiality (C:H), with no impact on integrity or availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on June 10, 2025, and was reserved in early April 2025. Given that Windows 10 Version 1809 is an older release, this vulnerability primarily affects legacy systems that have not been updated to more recent Windows versions. The out-of-bounds read could allow attackers to extract sensitive information such as memory contents that may include credentials or other private data, which could be leveraged for further attacks or privilege escalation if combined with other vulnerabilities.

For European organizations, the impact of CVE-2025-32719 depends largely on the prevalence of Windows 10 Version 1809 within their IT environments. Many enterprises have migrated to newer Windows versions, but legacy systems may still be in use, especially in industrial, governmental, or specialized environments where upgrading is slower. The vulnerability allows local attackers with some level of access to extract sensitive information, potentially exposing confidential data or credentials. This could facilitate insider threats or lateral movement within networks. While the vulnerability does not directly allow remote exploitation or system compromise, the confidentiality breach could undermine data protection obligations under regulations such as GDPR, leading to legal and reputational consequences. Organizations in sectors with high data sensitivity, such as finance, healthcare, and critical infrastructure, could face elevated risks if legacy systems remain unpatched. Additionally, the lack of known exploits reduces immediate risk but does not eliminate the threat of future weaponization.

To mitigate CVE-2025-32719, European organizations should prioritize upgrading affected systems from Windows 10 Version 1809 to supported and patched Windows versions, as this will inherently resolve the vulnerability. In environments where immediate upgrades are not feasible, organizations should implement strict local access controls to limit the ability of unauthorized or low-privileged users to execute code or access the vulnerable component. Employing application whitelisting and endpoint detection and response (EDR) solutions can help detect anomalous behavior indicative of exploitation attempts. Regularly auditing user privileges and removing unnecessary local accounts will reduce the attack surface. Network segmentation can also limit the impact of any local compromise. Monitoring for unusual memory access patterns or information disclosure attempts may provide early warning. Once Microsoft releases an official patch, prompt deployment is critical. Additionally, organizations should review and reinforce their data protection policies to ensure that any potential information leakage is contained and does not violate compliance requirements.
