Out of Bounds Write in GenieZone Due to Race Condition

Publication date: 2026-06-01

Last updated on: 2026-06-01

Assigner: MediaTek, Inc.

Description
In geniezone, there is a possible out of bounds write due to a race condition. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10873936; Issue ID: MSV-6786.

Executive Summary

This vulnerability exists in geniezone and is caused by a race condition that leads to a possible out of bounds write.

An out of bounds write means that the program writes data outside the boundaries of allocated memory, which can corrupt data or cause unexpected behavior.

The race condition implies that the vulnerability occurs when multiple processes or threads access shared data concurrently in an unsafe way.

Exploitation of this vulnerability could allow a malicious actor who already has System privilege to escalate their privileges locally.

User interaction is not required to exploit this vulnerability.

Impact Analysis

If exploited, this vulnerability can lead to local escalation of privilege for an attacker who already has System privilege.

This means an attacker with System-level access could gain even higher privileges or perform unauthorized actions on the affected system.

Since user interaction is not needed, the vulnerability could be exploited silently and potentially compromise system integrity.

Mitigation Strategies

To mitigate this vulnerability, apply the security patch identified as ALPS10873936 provided by MediaTek.

Since the vulnerability involves a race condition leading to out of bounds write and local privilege escalation, ensure that only trusted users have System privileges to reduce risk.
