CVE-2022-20413

Call-audio disclosure via flawed recording-state logic

Published Oct 11, 2022 · Updated Aug 3, 2024

Information disclosure in Android 10 through 13 Media Framework allows local users to record phone-call audio without interaction. The start routine in Threads.cpp applies flawed state logic that permits audio recording to begin while a phone call is active. Execution with User privileges is required, and exposure is limited to call audio; no integrity or availability impact is reported.
