Technical details
The vulnerability is an out-of-bounds write in MediaTek Modem caused by a missing bounds check, enabling local privilege escalation from System privilege level. Exploitation requires an attacker to already possess System privilege; no network access or user interaction is needed once that precondition is met. The flaw allows memory corruption that could lead to further privilege escalation on the device.
