CVE-2026-0096 Overview
CVE-2026-0096 is a user interface confusion vulnerability in the Android operating system. The flaw resides in the getAppLabel method of ForgetDeviceDialogFragment.java, a component involved in Bluetooth device pairing management. Misleading or insufficient UI rendering allows an attacker to trick the user into forgetting a paired device. Successful exploitation results in local escalation of privilege without requiring additional execution privileges. The vulnerability is categorized under [CWE-451] (User Interface Misrepresentation of Critical Information). Google addressed the issue in the June 2026 Android Security Bulletin.
Critical Impact
Local privilege escalation through UI spoofing in the Bluetooth device-forget dialog, affecting Android 16.0 and multiple QPR2 beta builds.
Affected Products
- Google Android 16.0
- Google Android 16.0 QPR2 Beta 1 and Beta 2
- Google Android 16.0 QPR2 Beta 3

Technical Details for CVE-2026-0096
Vulnerability Analysis
The vulnerability exists in the getAppLabel function within ForgetDeviceDialogFragment.java. This fragment is responsible for displaying the confirmation dialog when a user removes a paired Bluetooth or companion device. The dialog renders an application label that identifies the requesting app or device context. Insufficient validation or truncation of this label allows a malicious application to supply text that misrepresents the action being confirmed. The user sees a dialog that appears to perform a benign operation while the underlying action removes a trusted paired device.
This class of flaw maps to [CWE-451], where the security-relevant information presented to the user does not match the operation being authorized. Removing a paired device can downgrade trust relationships, sever secure channels, or force re-pairing under attacker-controlled conditions.
Root Cause
The root cause is improper handling of the application label string used to construct the dialog message. The getAppLabel routine returns a label that is rendered directly into the confirmation UI without sufficient constraints on length, content, or origin verification. A locally installed application with low privileges can manipulate this label to obscure the true intent of the dialog.
Attack Vector
The attack vector is local. A malicious application installed on the device, running with low privileges and no special permissions, can trigger the forget-device dialog with a crafted label. Because user interaction is not required for exploitation as scored, the attack path leads to local privilege escalation by manipulating trust state managed by the system. The advisory from Google should be consulted for the precise interaction surface. See the Android Security Bulletin June 2026 for technical details.

Detection Methods for CVE-2026-0096
Indicators of Compromise
- Unexpected removal of paired Bluetooth or companion devices from the Android device list without explicit user action.
- Installation of low-reputation applications shortly before paired-device trust loss.
- Repeated re-pairing prompts for previously trusted accessories.
Detection Strategies
- Inspect Android system logs (logcat) for BluetoothDevice unpair events correlated with foreground activity from third-party applications.
- Review MetricsEvent and CompanionDeviceManager audit entries for forget-device actions originating from non-system packages.
- Monitor enterprise mobile management (EMM) telemetry for changes to paired-device state on managed Android 16.0 devices.
Monitoring Recommendations
- Forward Android device event logs to a centralized analytics platform for correlation across the fleet.
- Alert on installations of applications that request Bluetooth or companion device APIs on patch-deficient devices.
- Track Android security patch level (ro.build.version.security_patch) and flag devices below the June 2026 baseline.
How to Mitigate CVE-2026-0096
Immediate Actions Required
- Apply the June 2026 Android security patch level (2026-06-01 or later) to all affected devices.
- Restrict installation of unvetted applications on Android 16.0 devices until patches are deployed.
- Audit currently paired Bluetooth and companion devices and re-validate trust relationships.
Patch Information
Google published fixes in the Android Security Bulletin June 2026. Devices reporting a security patch level of 2026-06-01 or later contain the corrected ForgetDeviceDialogFragment logic. Original equipment manufacturers (OEMs) distribute the patch through their standard update channels.
Workarounds
- Disable Bluetooth and companion device features on unpatched devices where operationally feasible.
- Enforce application allowlisting through mobile device management (MDM) policies to block untrusted installers.
- Educate users to scrutinize device-forget dialogs and cancel any unexpected confirmation prompts.
# Verify the Android security patch level on a connected device
adb shell getprop ro.build.version.security_patch
# Expected output for patched devices: 2026-06-01 or later
