Android local code exec exploited in the wild (CVE-2025-48595)

Actively exploited in the wild - CVE-2025-48595 is a high-severity integer overflow in Android that allows an attacker to achieve local code execution without any privileges or user interaction. This vulnerability is confirmed exploited in the wild by CISA, and the Android security patch must be applied immediately.

Overview

CVE-2025-48595 is an integer overflow vulnerability in multiple locations within the Android operating system. An integer overflow occurs when an arithmetic operation attempts to create a numeric value that is outside of the range that can be represented with a given number of bits. In this case, the overflow can be triggered to overwrite critical memory regions, leading to arbitrary code execution.

The CVSS score of 8.4 (HIGH) reflects the ease of exploitation: the attack vector is LOCAL, the complexity is LOW, no privileges are required, and no user interaction is needed. This means an attacker who already has a foothold on a device - via a malicious app or compromised system process - can immediately escalate privileges and execute arbitrary code with higher system-level permissions.

Impact

A successful exploit of CVE-2025-48595 allows an attacker to execute arbitrary code in the context of a privileged system process. This local escalation of privilege can lead to full device compromise, including the ability to install persistent malware, steal sensitive data (contacts, messages, credentials), bypass security controls, and monitor user activity. Attackers can also use this as a stepping stone to pivot to other devices on a corporate network.

Remediation and Mitigation

The only effective remediation is to install the Android security update that patches CVE-2025-48595. Since this is a platform-level vulnerability in the Android OS itself, users must apply the monthly security patch from their device manufacturer or carrier. Google has included the fix in the latest Android security bulletin.

Action steps:

1. Update immediately: Go to Settings > Security & privacy > System updates and install the latest update.
2. Enterprise devices: IT teams should push the latest Android security patch level to all managed devices through Mobile Device Management (MDM) solutions.
3. No workarounds exist: There are no reliable mitigations for this vulnerability other than patching. Blocking sideloaded apps or restricting app installations will not prevent exploitation because the flaw does not require user interaction.

Security Insight

CVE-2025-48595 is a reminder that integer overflows remain a stubborn class of vulnerability even in mature codebases like Android. The fact that this flaw requires no privileges and no user interaction to exploit makes it a highly attractive target for surveillanceware and spyware vendors who prize stealthy, zero-click privilege escalation. This vulnerability is a strong signal that the Android platform’s memory-safety boundaries still have gaps, and organizations that rely on older devices no longer receiving security patches face a permanent and unpatched risk.
