CVE-2022-42514

Local information disclosure via unchecked buffer bounds

Published Dec 16, 2022 · Updated Apr 17, 2025

Out-of-bounds read in the Android kernel allows local users with System privileges to disclose adjacent memory without user interaction. ProtocolImsBuilder::BuildSetConfig in protocolimsbuilder.cpp reads past a buffer boundary because it omits a required bounds check. Exploitation requires System execution privileges and is limited to local information disclosure; integrity and availability are unaffected.
