In hasInteractAcrossUsersFullPermission of AppInfoBase.java, there is a possible cross-user permission bypass due to a confused deputy. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
Executive ViewAI
A high-severity local privilege escalation vulnerability affects Android devices up to version 14.0, potentially allowing attackers to gain elevated system access without requiring special permissions. Organizations with Android device deployments face elevated risk of unauthorized access to sensitive data and system compromise, particularly if devices are used for corporate communications or data access.
Enforce mandatory device encryption and strong authentication (PIN/biometric). Restrict physical device access and implement mobile device management (MDM) to monitor for unauthorized privilege escalation. Disable Bluetooth and unnecessary connectivity when not in use. Segment Android devices from critical enterprise networks. Monitor system logs for suspicious privilege elevation attempts. Require regular security updates as they become available. Consider restricting sensitive operations to patched devices only.
