CVE-2025-29824 is a use-after-free vulnerability identified in the Windows Common Log File System Driver component of Microsoft Windows 10 Version 1507 (build 10.0.10240.0). Use-after-free (CWE-416) vulnerabilities occur when a program continues to use memory after it has been freed, potentially leading to arbitrary code execution or privilege escalation. In this case, the flaw allows an authorized local attacker—someone with limited privileges on the system—to exploit the vulnerability to elevate their privileges to SYSTEM level. The vulnerability does not require user interaction and has a low attack complexity, meaning it can be reliably exploited under normal conditions. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, as well as ease of exploitation. The vulnerability affects only the initial release of Windows 10 (Version 1507), which is an older and largely unsupported version. No public exploits have been reported yet, but the presence of a fully functional exploit is plausible given the nature of use-after-free bugs in kernel drivers. The vulnerability was reserved in March 2025 and published in April 2025, with no patches currently available, indicating that affected organizations must rely on mitigations or upgrade paths. The Common Log File System Driver is a core component responsible for managing transaction logs for file systems, so exploitation could compromise system stability and security.

The impact of CVE-2025-29824 is significant for organizations still running Windows 10 Version 1507. Successful exploitation allows an attacker with local access to escalate privileges to SYSTEM, effectively gaining full control over the affected machine. This can lead to unauthorized access to sensitive data, installation of persistent malware, disabling of security controls, and disruption of system availability. Because the vulnerability affects a kernel-mode driver, exploitation could also cause system crashes or instability. Organizations relying on legacy Windows 10 versions, especially in industrial, governmental, or critical infrastructure environments, face increased risk of targeted attacks. The lack of user interaction requirement and low complexity of exploitation make it easier for attackers to leverage this vulnerability in automated or semi-automated attacks. Although no known exploits are currently in the wild, the vulnerability’s characteristics suggest it could be weaponized quickly once a public exploit is developed. The scope is limited to Windows 10 Version 1507, but any unpatched systems remain at high risk.

1. Upgrade affected systems to a supported and fully patched version of Windows 10 or later, as Windows 10 Version 1507 is outdated and no longer supported by Microsoft. 2. If upgrading is not immediately possible, restrict local access to affected systems by enforcing strict access controls and limiting administrative privileges. 3. Employ application whitelisting and endpoint protection solutions that can detect and block suspicious privilege escalation attempts. 4. Monitor system logs and security telemetry for unusual behavior indicative of exploitation attempts, such as unexpected process launches or privilege escalations. 5. Disable or limit use of the Common Log File System Driver if feasible, or apply any interim mitigations recommended by Microsoft once available. 6. Implement network segmentation to isolate legacy systems and reduce the risk of lateral movement if compromise occurs. 7. Maintain an accurate inventory of systems running Windows 10 Version 1507 to prioritize remediation efforts. 8. Stay informed on Microsoft advisories for patches or workarounds related to this CVE and apply them promptly upon release.
