CVE-2026-21029

Local privilege escalation via exported application components

Published Jun 5, 2026 · Updated Jun 5, 2026

Improper component export in Samsung Galaxy Editing Service before SMR Jun-2026 Release 1 allows local users to execute privileged operations. The service exposes Android application components without proper access control, allowing a low-privileged caller to reach operations executed with elevated privileges. Samsung has not identified the specific exported components or callable operations; exploitation requires local low-privileged access on an affected device running Android 14, 15, or 16.
