Local privilege escalation via Cdpsvc use-after-free
Published Sep 8, 2026 · Updated Sep 9, 2026
Use-after-free in Microsoft Windows Cdpsvc allows local users with low privileges to elevate privileges on affected Windows 10, 11, and Server systems. Cdpsvc accesses an object after releasing its memory, leaving a stale reference that can be manipulated during a high-complexity local attack; Microsoft has not disclosed the responsible function or object lifecycle. Successful exploitation requires an existing low-privileged account and can grant elevated control without user interaction.
