CVE-2022-20562

Call-audio disclosure via audio processor logic error

Published Dec 16, 2022 · Updated Apr 21, 2025

Information disclosure in Google Pixel's audio processor allows local users to record call audio through an Android kernel logic error. Various functions in ap_input_processor.c incorrectly permit audio recording during a phone call, although Google has not disclosed the specific faulty branch or state transition. Exploitation requires User execution privileges on the Pixel device, needs no user interaction, and exposes call audio without reported integrity or availability impact.
