CVE-2026-0085

Local denial of service via case-mismatched columns

Published Jun 1, 2026 · Updated Jun 1, 2026

Improper input validation in Android 14, 15, 16, and 16-qpr2 allows local users to crash Contacts Provider with an oversized contact name. applySimpleFieldMaxSize in DataRowHandler.java matches column keys case-sensitively, so mixed-case keys such as DaTa1 bypass length truncation. A low-privileged local user can trigger the availability-only failure without user interaction; no data disclosure or modification is reported.
