CVE-2025-48595 Android Zero-Day Under Active Exploit

Google has released the June 2026 Android security update, patching 124 vulnerabilities across the mobile operating system. One high-severity flaw in the Android Framework component, tracked as CVE-2025-48595, is already under active exploitation in targeted attacks.

What Happened: CVE-2025-48595 Android Zero-Day Under Active Exploit

Google disclosed CVE-2025-48595 on June 2, 2026, alongside the monthly Android security bulletin. The vulnerability carries a CVSS score of 8.4 and allows local privilege escalation without user interaction. In other words, an attacker with minimal access on a device can exploit this flaw to gain elevated privileges and potentially execute arbitrary code.

Google confirmed the vulnerability is seeing “limited, targeted exploitation.” Consequently, this is not a theoretical risk; threat actors are actively leveraging it in the wild. The issue affects Android versions 14, 15, 16, and 16 QPR2.

Technical Details of the CVE-2025-48595 Vulnerability

CVE-2025-48595 stems from an integer overflow in multiple locations within the Android Framework. Because of the overflow, an attacker can trigger code execution, leading to local escalation of privilege. No additional execution privileges are needed, and no user interaction is required.

The following technical points summarize the attack surface:

• Attack Vector: Local exploitation via integer overflow
• Privileges Required: None beyond initial local access
• User Interaction: Not required
• Impact: Local escalation of privilege, possible arbitrary code execution
• Affected Versions: Android 14, 15, 16, and 16 QPR2
• CVSS Score: 8.4 (High)

Google also released a second patch level, 2026-06-05, which includes all fixes from the first set plus patches for the Linux kernel and third-party chipset components from Imagination Technologies, MediaTek, Qualcomm, and Unisoc.

Business and Operational Impact

The exploitation of CVE-2025-48595 carries significant risk for organizations and individuals. Because the flaw enables privilege escalation without user interaction, it is especially attractive to advanced threat actors and commercial spyware vendors.

• Targeted Surveillance: Similar Android Framework flaws have been weaponized by commercial spyware vendors to compromise high-profile individuals.
• Enterprise Exposure: Organizations with bring-your-own-device policies or managed Android fleets face elevated risk until patches are applied.
• Data Exfiltration: Elevated privileges can lead to unauthorized access to sensitive applications, files, and communications.
• Supply Chain Risk: Devices running older chipsets may depend on OEM partners to deliver updates on time.

Mitigation and Recommendations

Immediate Actions for Defenders

1. Apply the June 2026 Android security patches immediately on all supported devices.
2. Verify patch levels are 2026-06-01 or 2026-06-05 on enterprise-managed devices.
3. Monitor for anomalous privilege escalation activity on Android endpoints.
4. Restrict installation of unknown applications until devices are fully patched.

Long-Term Recommendations

Enterprises should enforce minimum patch level policies through mobile device management solutions. Moreover, they should review mobile threat detection capabilities to identify post-exploitation behavior. Finally, users should enable automatic security updates where available and avoid sideloading apps from untrusted sources.

Bottom line: CVE-2025-48595 is a high-severity, actively exploited Android privilege escalation flaw with no user interaction required. Apply the June 2026 security patches without delay to mitigate targeted exploitation.
