CVE-2026-24292 is a use-after-free vulnerability classified under CWE-416 found in the Connected Devices Platform Service (Cdpsvc) component of Microsoft Windows 10 Version 1809 (build 10.0.17763.0). The vulnerability arises when Cdpsvc improperly manages memory, freeing an object while it is still in use, which can lead to memory corruption. An authorized attacker with local access and limited privileges can exploit this flaw to execute arbitrary code with elevated privileges, effectively escalating their rights on the system. The vulnerability does not require user interaction and has a CVSS v3.1 base score of 7.8, indicating high severity. The attack vector is local (AV:L), with low attack complexity (AC:L), requiring privileges (PR:L) but no user interaction (UI:N). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Although no exploits are currently known in the wild, the vulnerability poses a significant risk to affected systems. The affected Windows 10 version 1809 is an older release, which may still be operational in some enterprise or industrial environments. No patches are currently linked, so mitigation depends on applying forthcoming updates or implementing compensating controls. The vulnerability was reserved in January 2026 and published in March 2026, reflecting recent discovery and disclosure.

If exploited, this vulnerability allows an attacker with local access and limited privileges to escalate their privileges to SYSTEM or equivalent, potentially gaining full control over the affected machine. This can lead to unauthorized access to sensitive data, installation of persistent malware, disruption of system operations, and lateral movement within a network. The high impact on confidentiality, integrity, and availability means that critical systems running Windows 10 Version 1809 could be severely compromised. Organizations relying on this OS version, especially in sectors like government, finance, healthcare, and critical infrastructure, face increased risk of targeted attacks. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as weaponization could occur rapidly after public disclosure. Legacy systems that cannot be upgraded remain vulnerable, increasing the attack surface for adversaries.

Organizations should prioritize upgrading from Windows 10 Version 1809 to a supported and patched Windows version to eliminate exposure. Until patches are available, restrict local access to trusted users only and enforce the principle of least privilege to minimize the number of accounts with local access. Employ application whitelisting and endpoint detection and response (EDR) solutions to monitor for suspicious behavior indicative of exploitation attempts. Regularly audit and harden Connected Devices Platform Service permissions and configurations. Network segmentation can limit lateral movement if a system is compromised. Maintain up-to-date backups and incident response plans to recover quickly from potential breaches. Monitor vendor advisories for the release of official patches and apply them promptly once available. Consider disabling or restricting Cdpsvc if it is not required in the environment, after assessing operational impact.
