CVE-2022-20032

Local information disclosure via VOW driver race

Published Feb 9, 2022 · Updated Aug 3, 2024

An out-of-bounds read in MediaTek's VOW driver allows local users to disclose information on affected Android 10.0, 11.0, and 12.0 devices. A race condition permits concurrent driver operations to corrupt memory and read beyond intended bounds; MediaTek has not disclosed the affected function or shared resource. Exploitation requires System execution privileges and no user interaction, and the documented consequence is local information disclosure only.
