CVE-2025-48643 Overview
CVE-2025-48643 is a high-severity provisioning bypass vulnerability affecting Google Android 17.0. The flaw stems from improper input validation [CWE-20] in multiple locations within the operating system. A local attacker with low privileges can exploit this weakness to escalate privileges on the affected device. Exploitation requires no user interaction and no additional execution privileges beyond an already-running unprivileged context. Google documented the issue in the Android Security Bulletin for release 17.
Critical Impact
Local attackers can bypass provisioning controls and achieve privilege escalation on Android 17.0 devices without user interaction, leading to full confidentiality, integrity, and availability impact.
Affected Products
- Google Android 17.0
- Devices built on the Android 17 platform that have not received the security bulletin patch
- Components referenced in the Android Security Bulletin #17 advisory
Discovery Timeline

Technical Details for CVE-2025-48643
Vulnerability Analysis
The vulnerability is classified as Improper Input Validation [CWE-20] occurring in multiple code locations within Android 17.0. Inputs that should be validated against the device provisioning state are accepted without sufficient checks. As a result, the provisioning workflow can be bypassed by a local process that supplies crafted parameters. Successful exploitation grants elevated privileges that would normally require completing the provisioning flow.
Google marks the issue with high confidentiality, integrity, and availability impact, reflecting a full compromise of the affected user or system context. The attack vector is local, meaning the adversary requires existing code execution on the device, such as through a malicious application. Because user interaction is not required, automated abuse from a background app or compromised service is feasible.
Root Cause
The root cause is missing or insufficient validation of inputs that gate provisioning decisions. When the affected code paths process untrusted parameters, they fail to confirm that the caller, the data, or the device state satisfy required preconditions. This permits state transitions that should be reserved for trusted provisioning flows.
Attack Vector
An attacker leverages a local, low-privileged context, such as an installed application, to invoke the vulnerable code paths with malformed or unexpected inputs. The validation gap allows the request to proceed, bypassing provisioning checks and elevating the caller's effective privileges. No user prompt or interaction is required during exploitation.
No public proof-of-concept code is available. Refer to the Android Security Bulletin #17 for vendor-supplied technical details.
Detection Methods for CVE-2025-48643
Indicators of Compromise
- Unexpected changes to device provisioning state, owner, or profile configuration outside of a managed enrollment flow.
- Applications invoking provisioning-related system APIs or intents from non-system contexts.
- Privilege transitions in system logs (logcat) that do not correspond to a legitimate setup or MDM action.
Detection Strategies
- Audit installed applications on Android 17.0 devices for those requesting device administration, device owner, or provisioning-related capabilities without a clear business need.
- Compare device build fingerprints and security patch levels against the Android 17 bulletin to identify unpatched endpoints.
- Correlate mobile threat defense telemetry with sudden changes in device management posture or policy state.
Monitoring Recommendations
- Forward Android device logs and MDM events to a central SIEM and alert on unauthorized provisioning state changes.
- Track applications that gain elevated permissions or device owner status outside of provisioning windows.
- Monitor enterprise fleets for devices that fall behind on the security patch level documented in Android Security Bulletin #17.
How to Mitigate CVE-2025-48643
Immediate Actions Required
- Apply the security patch level published in the Android Security Bulletin #17 as soon as it is available from the device OEM.
- Inventory all Android 17.0 devices in the environment and prioritize patching based on data sensitivity and exposure.
- Restrict installation of untrusted applications by enforcing Google Play Protect and managed app catalogs through MDM.
Patch Information
Google has addressed CVE-2025-48643 in the Android 17 security bulletin. Device manufacturers ship the fix as part of the corresponding monthly security patch level. Administrators should verify that managed devices report the patched security patch level after the OEM update is delivered. See the Android Security Bulletin #17 for component-level details.
Workarounds
- Where patches are unavailable, restrict device enrollment and provisioning operations to trusted networks and supervised conditions.
- Enforce MDM policies that block sideloading and unknown sources to reduce the chance of a malicious local app reaching the device.
- Disable or remove non-essential applications on high-value devices until the security patch level is updated.
