CVE-2024-20096

Local information disclosure via unchecked m4u read

Published Oct 7, 2024 · Updated Oct 27, 2024

Out-of-bounds read in MediaTek m4u on Android 12.0, 13.0, 14.0, and 15.0 allows System-privileged local users to disclose memory. The component reads beyond an intended buffer because a required bounds check is missing; MediaTek has not disclosed the affected function or input. Exploitation requires prior System-level execution, needs no user interaction, and affects only the listed MediaTek chipsets and Android releases.
