CVE-2025-60706 is a security vulnerability classified as CWE-125 (Out-of-bounds Read) found in the Windows Hyper-V virtualization component of Microsoft Windows 10 Version 1809 (build 10.0.17763.0). This vulnerability allows an attacker with authorized local access and limited privileges (PR:L) to perform an out-of-bounds read operation, which can lead to the disclosure of sensitive information from memory. The flaw arises because Hyper-V improperly handles memory boundaries, enabling an attacker to read data beyond the intended buffer limits. This can expose confidential information that could be leveraged for further attacks or privilege escalation. The vulnerability does not require user interaction (UI:N) and does not impact system integrity or availability, limiting its scope to confidentiality breaches. The attack vector is local (AV:L), meaning an attacker must have some level of access to the affected system, such as a logged-in user or a process running with limited privileges. The CVSS v3.1 base score is 5.5, indicating a medium severity level. No public exploits or active exploitation in the wild have been reported as of the publication date (November 11, 2025). Since the affected product is an older Windows 10 version, many organizations may have already migrated to newer versions, but legacy systems remain vulnerable. The vulnerability highlights the importance of securing virtualization environments and controlling local access to systems running Hyper-V. Microsoft has not yet published a patch link, so organizations should monitor for updates and apply them promptly once available.

For European organizations, the primary impact of CVE-2025-60706 is the potential disclosure of sensitive information from systems running Windows 10 Version 1809 with Hyper-V enabled. This could include confidential data residing in memory, such as cryptographic keys, credentials, or proprietary information. Although the vulnerability does not allow direct code execution or system disruption, information disclosure can facilitate further attacks, including privilege escalation or lateral movement within networks. Organizations relying on legacy Windows 10 systems, especially in sectors with strict data protection requirements like finance, healthcare, and government, face increased risk of data breaches. The local attack vector means that insider threats or compromised user accounts could exploit this vulnerability. Additionally, virtualized environments are often used for critical workloads, so any compromise of confidentiality can have cascading effects. The absence of known exploits reduces immediate risk, but the medium severity rating and the presence of vulnerable systems in European enterprises warrant proactive mitigation. Failure to address this vulnerability could lead to compliance issues under GDPR if personal data is exposed.

To mitigate CVE-2025-60706, European organizations should: 1) Prioritize patch management by monitoring Microsoft security advisories and applying updates for Windows 10 Version 1809 Hyper-V as soon as patches are released. 2) Restrict local access to systems running Hyper-V, enforcing the principle of least privilege and limiting user accounts with Hyper-V usage rights. 3) Implement strict access controls and monitoring on virtualization hosts to detect unusual local activities that could indicate exploitation attempts. 4) Consider upgrading affected systems to supported Windows versions with improved security and ongoing support to reduce exposure to legacy vulnerabilities. 5) Use endpoint detection and response (EDR) tools to identify anomalous memory access patterns or suspicious local processes. 6) Conduct regular security audits of virtualization environments to ensure compliance with security policies. 7) Educate users about the risks of local privilege abuse and enforce strong authentication mechanisms to prevent unauthorized local access. These steps go beyond generic advice by focusing on controlling local access and securing virtualization hosts specifically.
