Local information disclosure via missing APU bounds check
Published Mar 7, 2023 · Updated Mar 6, 2025
Out-of-bounds read in the MediaTek APU on Android 12.0 and 13.0 allows local users with System privileges to disclose information. The APU component reads outside the intended memory bounds because it omits a required bounds check; MediaTek has not disclosed the affected function or data path. Exploitation requires System execution privileges, needs no user interaction, and is limited to devices using one of the listed chipsets.
