Local privilege escalation via coarse SDMA access controls
Published Jul 14, 2026 · Updated Jul 14, 2026
Access-control granularity failure in Surface Broker SDMA on affected Microsoft Surface devices allows local users to elevate privileges. Microsoft identifies insufficiently granular SDMA access control but has not disclosed the specific broker operation, protected asset, or attacker-controlled input. Exploitation requires low-privileged local access; the disclosed impact is privilege elevation, but the resulting privilege level is unspecified.
