CVE-2025-48595: Android Framework Integer Overflow Vulnerability

This vulnerability is an integer overflow in the Android Framework that can result in local privilege escalation through code execution on affected devices. It matters because the flaw resides in core system components that run with elevated privileges, so successful local exploitation can expand an attacker's foothold without requiring remote access.

How it works

The weakness is categorized as CWE-190, an integer overflow or wraparound. In this class of flaw, arithmetic operations on integer values exceed the maximum representable value for the data type, producing an unexpected result such as an undersized buffer allocation or incorrect bounds check.

An attacker with the ability to supply crafted input to the affected code path can trigger the overflow. The resulting incorrect state may then be leveraged to execute arbitrary code at a higher privilege level on the device. Specific trigger conditions, affected code paths, and required attacker context must be confirmed against the vendor advisory.

Am I affected? How to find it in your systems

The vulnerability affects the Android Framework, the core set of libraries and services that underpin Android devices. Inventory begins with identifying managed Android endpoints through enterprise mobility management platforms, device management consoles, or asset inventories that record OS build fingerprints.

• Compare installed framework versions and security patch levels against the vendor advisory to determine exposure.
• Review application and system logs for anomalies in memory allocation or process behavior that could indicate attempted exploitation of integer-handling routines, though such signals are typically low-visibility for local flaws.
• Pay particular attention to devices that run third-party or custom ROMs where framework modifications may alter the presence of the defect.

How to remediate

Apply the vendor-supplied update referenced in the official advisory as the primary remediation. The update addresses the integer-handling error in the framework components.

• After patching, verify that the new build appears in device reporting and that the security patch level advances past the vulnerable range.
• Enforce least-privilege application permissions and review any custom or pre-installed applications that interact directly with framework APIs handling numeric inputs or memory buffers.
• Follow applicable BOD 22-01 guidance for any cloud-managed Android services associated with the devices.

If you can't patch immediately

Until patches can be deployed, reduce exposure by applying mitigations described in the vendor advisory. Where mitigations are unavailable, discontinue use of the affected devices or isolate them from sensitive data and networks.

• Segment mobile device traffic and limit the ability of untrusted applications to interact with privileged framework services.
• Monitor endpoint detection and response telemetry for unusual local process behavior or privilege changes on Android devices.
• Consider virtual patching or policy controls that restrict execution of code paths known to exercise the vulnerable integer operations, confirming feasibility against vendor documentation.

If your data may have been exposed

Local privilege-escalation vulnerabilities that are actively exploited can contribute to device compromise and subsequent data exposure. Organizations can run a free exposure scan of employee email addresses against known breach datasets to identify accounts that may already appear in public breach records.
