Executive brief
A security vulnerability exists in MediaTek's GenieZone, a secure execution environment component. A malicious actor who has already gained high-level 'System' privileges on a device could exploit a timing-related flaw to gain even deeper control over the system. This could allow an attacker to bypass security boundaries and maintain persistent, unauthorized access to the device's most sensitive operations.
Technical details
A race condition (CWE-367: Time-of-check Time-of-use) exists within the MediaTek GenieZone environment. The vulnerability stems from improper synchronization that allows an out-of-bounds write operation. To exploit this, an attacker must already have 'System' level privileges on the local device. Successful exploitation allows for further escalation of privilege within the secure environment. No user interaction is required for exploitation. MediaTek has released a fix under Patch ID ALPS10873936.
