CVE-2023-29753Public exploit

Persistent app crash via unbounded preference insertion

Published Jun 9, 2023 · Updated Jan 6, 2025

Denial of service in EKATOX APPS Facemoji Emoji Keyboard 2.9.1.2 for Android allows local users to persistently crash the app. An exposed content provider accepts inserts from unauthorized apps into arbitrary SharedPreference files, allowing persistent data to grow without bounds and load at startup. A local malicious app can repeatedly write large keys and values until startup exhausts memory, leaving the keyboard in a persistent crash loop.
