CVE-2022-20101

Local information disclosure via aee path traversal

Published May 3, 2022 · Updated Aug 3, 2024

Path traversal in MediaTek's aee daemon on Android 11.0 and 12.0 allows local users to disclose information through a crafted path. MediaTek identifies the aee daemon as the locus but does not disclose which path-handling operation accepts the untrusted pathname or which files are exposed. A low-privileged local user can exploit the flaw without user interaction; the reported consequence is limited to confidentiality.
