Remote information disclosure via unchecked pitch value
Published Jun 22, 2021 · Updated Aug 3, 2024
Out-of-bounds read in Android 11 Media Framework allows remote attackers to disclose memory after required user interaction. Lag_max in p_ol_wgh.cpp indexes the correlation buffer using an unvalidated pitch-derived value, so an out-of-range value reads past the buffer. The flaw requires user interaction but no prior privileges; its reported consequence is memory disclosure, not modification or service interruption.
