Local information disclosure via incorrect VOW bounds check

Published Sep 6, 2022 · Updated Aug 3, 2024

Out-of-bounds read in MediaTek VOW on listed chipsets with Android 11.0 or 12.0 allows local users to read beyond the intended buffer. The VOW component applies an incorrect bounds check before reading data; MediaTek has not disclosed the affected code path or input. Exploitation requires System execution privileges but no user interaction, and the reported consequence is local information disclosure only.
