CVE-2026-58874

Local privilege escalation via unchecked SMS dispatch

Published Sep 8, 2026 · Updated Sep 8, 2026

Improper privilege management in Google Android 14, 15, 16, and 16-qpr2 allows local users to elevate privileges through SmsController. The sendStoredText and sendStoredMultipartText paths in SmsController.java omit a subscription-to-user permission check before dispatching stored SMS messages. A low-privileged local process can reach the affected calls without user interaction, gaining higher privileges over protected device resources.
