Microsoft Windows: Heap-based buffer overflow in Devices Human Interface allows privilege escalation
Summary
A heap-based buffer overflow in the Windows Devices Human Interface component allows a locally authorized user to elevate privileges to SYSTEM. The attack requires physical access to the device and a low-privilege local account. An attacker with physical access, for example to a lost laptop or shared workstation, could gain full control over the affected system once exploited.

Workaround
Unknown.
Exploitation
- No known exploitation in the wild.
- No public proof of concept found.
- Microsoft Exploitability Index as reported by Rapid7: Exploitation Less Likely.
- CISA SSVC: exploitation none, not automatable.
Our recommendation
- Apply the November 2026 cumulative update to all affected Windows systems, prioritising laptops and shared workstations.
- Enable full disk encryption and enforce strong logon and screen-lock policies on mobile devices.
- Restrict unmanaged USB ports and physical access to workstations through policy.
- Verify the fixed build numbers against the MSRC entry before rollout.
