CVE-2025-20665

Device identifier disclosure via missing SELinux policy

Published May 5, 2025 · Updated May 12, 2025

Information disclosure in MediaTek devinfo on Android 13.0, 14.0, and 15.0 allows local users to read a device identifier. A missing SELinux policy leaves device-identifying information in the devinfo component accessible to an unauthorized local process. Exploitation requires local code execution with low privileges, needs no user interaction, and has no reported write or service-interruption impact.
