CVE-2025-62572 is an out-of-bounds read vulnerability classified under CWE-125, discovered in the Application Information Services component of Microsoft Windows 11 Version 24H2 (build 10.0.26100.0). This vulnerability allows an authorized local attacker to read memory outside the intended buffer boundaries, which can lead to privilege escalation by exposing sensitive data or corrupting memory structures critical for security enforcement. The flaw does not require user interaction but does require the attacker to have some level of local privileges (PR:L). The vulnerability affects confidentiality, integrity, and availability, as indicated by the CVSS vector (C:H/I:H/A:H). The attack vector is local (AV:L), and the attack complexity is low (AC:L), meaning exploitation is feasible with limited conditions. No known exploits have been reported in the wild yet, but the vulnerability is publicly disclosed and rated as high severity with a CVSS score of 7.8. The absence of a patch link suggests that a fix may be forthcoming or pending deployment. This vulnerability is significant because it can be leveraged by attackers who have gained limited access to escalate privileges to SYSTEM or equivalent, thereby compromising the entire system. The Application Information Services component is critical for managing application execution contexts, making this vulnerability a serious threat to Windows 11 environments.

The impact of CVE-2025-62572 is substantial for organizations using Windows 11 Version 24H2. Successful exploitation can lead to local privilege escalation, allowing attackers with limited access to gain SYSTEM-level privileges. This elevation can enable attackers to install malware, disable security controls, access sensitive data, and move laterally within networks. The vulnerability affects confidentiality by exposing memory contents, integrity by potentially corrupting security-critical data structures, and availability by enabling disruptive actions. Organizations relying on Windows 11 for endpoint devices, especially those in sensitive sectors like finance, healthcare, government, and critical infrastructure, face increased risk of compromise. Since the attack requires local access, insider threats or attackers who have already breached perimeter defenses could leverage this flaw to deepen their foothold. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as public disclosure often leads to rapid development of exploit code.

To mitigate CVE-2025-62572, organizations should: 1) Monitor Microsoft security advisories closely and apply patches immediately once released to address this vulnerability. 2) Restrict local user privileges rigorously, ensuring users operate with the least privilege necessary to reduce the attack surface. 3) Employ application whitelisting and endpoint detection and response (EDR) solutions to detect and block suspicious local privilege escalation attempts. 4) Harden systems by disabling unnecessary services and restricting access to Application Information Services where feasible. 5) Conduct regular audits of local accounts and permissions to identify and remediate excessive privileges. 6) Implement network segmentation to limit lateral movement opportunities if local compromise occurs. 7) Educate users and administrators about the risks of local privilege escalation and the importance of maintaining updated systems. These steps, combined with timely patching, will reduce the likelihood and impact of exploitation.
