Local privilege escalation via DA bounds-check omission
Published Nov 4, 2024 · Updated Nov 4, 2024
Out-of-bounds write in MediaTek DA allows local users to escalate privileges on affected chipsets with user interaction. The DA component writes beyond a buffer because it omits a bounds check; MediaTek has not identified the affected function or input format. Exploitation requires user interaction but no additional execution privileges, and success grants elevated local privileges.
