Executive brief
A race condition vulnerability exists in MediaTek chipset display drivers that allows privilege escalation. An attacker who already holds System-level privileges can exploit this to elevate privileges further, with no user interaction required. This could be leveraged as part of a multi-stage attack to gain complete control of affected devices.
Technical details
The vulnerability is a race condition in the display subsystem that leads to local privilege escalation. The vulnerability requires that an attacker has already obtained System privilege level access; no additional user interaction is needed for exploitation. The exact vulnerable component and root cause are not detailed in the available information, but the race condition allows privilege boundary bypass. A patch has been issued (Patch ID: ALPS11019183) by MediaTek and is available through their August 2026 security bulletin.
