Microsoft Windows Cdpsvc: Elevation of privilege via use-after-free
Summary
The Connected Devices Platform Service (Cdpsvc) in multiple Windows 10, Windows 11 and Windows Server versions contains a use-after-free flaw. An authorized local user can exploit it to gain higher privileges on the affected system. Exploitation requires high complexity and local access, so an attacker needs an existing foothold on the host first. On an affected host, the impact on confidentiality, integrity and availability is rated high.

Exploitation
- CISA SSVC: Exploitation none, Automatable no, Technical impact total.
- Not listed as exploited in the wild.
- No public proof of concept found.
Our recommendation
- Install the November 2026 Windows security update on all affected systems, prioritising terminal servers, RDS hosts, shared workstations and systems used by contractors.
- Confirm that the update is installed and that the Cdpsvc service runs normally.
- Restrict local logons to trusted users and monitor for unexpected privilege changes.
