CVE-2024-20103Network attack vector

Remote code execution via unchecked firmware input

Published Oct 7, 2024 · Updated Oct 7, 2024

Out-of-bounds write in MediaTek wlan firmware on affected Android 13.0 through 15.0 devices allows remote attackers to execute code. The firmware improperly validates input before writing it to memory, allowing data to pass beyond the intended buffer; MediaTek has not disclosed the affected routine or input field. No authentication, additional execution privileges, or user interaction is required, and successful exploitation compromises device confidentiality, integrity, and availability.
