CVE-2024-20098

System-privileged escalation via unchecked power write

Published Oct 7, 2024 · Updated Oct 7, 2024

Out-of-bounds write in MediaTek chipset power components on Android 12.0, Android 15.0, and Yocto 4.0 allows local users to escalate privileges. The power component writes beyond a buffer because it fails to check a boundary; MediaTek has not disclosed the affected function or input path. Exploitation requires existing System execution privileges, needs no user interaction, and can further elevate privileges, although the resulting privilege level is undisclosed.
