Executive Summary

This vulnerability exists in multiple functions of GrantPermissionsActivity.java where a user can be tricked into granting incorrect permissions due to permission overload. This means an app can present multiple permission requests simultaneously, confusing the user and potentially causing them to grant more permissions than intended. Exploiting this flaw can lead to local escalation of privilege without needing additional execution privileges or user interaction. [2]

Impact Analysis

The vulnerability can lead to local escalation of privilege on the affected device. An attacker could exploit the permission overload to gain higher privileges than intended by tricking the user into granting incorrect permissions. This could compromise the security of the device and potentially allow unauthorized actions or access to sensitive data without requiring additional execution privileges or user interaction.

Mitigation Strategies

Apply the Android security updates that include the patch for CVE-2025-26420. Specifically, update your device or system to include the changes made to the PermissionController component, which restricts apps from showing multiple permission request dialogs simultaneously. This patch is included in updates merged by March 12, 2025. Ensuring your system is updated to the latest Android security patch level will mitigate this vulnerability. [2]
