CVE-2026-55262

Summary

The flaw is a policy desynchronization in NotificationManagerService.java caused by insufficient input validation when setting notification listener access for a user, allowing an unprivileged local attacker to bypass intended restrictions and gain elevated privileges without user interaction.

Exploitability

Exploitation requires local access and no additional privileges, but the exact trigger condition is not specified, making reliable exploitation difficult without deeper knowledge of internal state transitions.

Blast radius

Successful exploitation could allow a local attacker to fully compromise the device—reading sensitive data, modifying system behavior, and crashing services—without requiring user interaction or elevated credentials.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Apply the official patch released in Android Security Bulletin 2026-10 (patch level 2026-10-05) or later, which addresses the input validation issue in NotificationManagerService.setNotificationListenerAccessGrantedForUserInternal().
