CVE-2025-48595: Android integer overflow bug patched in June 2026

Google’s June 2026 Android security update includes a fix for CVE-2025-48595, an integer overflow that can enable code execution and local privilege escalation on affected devices. According to the Android Security Bulletin—June 2026, the flaw requires no additional execution privileges and no user interaction to be exploited.

Why it matters: local escalation paths are valuable to attackers because they can turn limited code execution into broader control of a device. BleepingComputer reports that Google indicated signs of “limited, targeted exploitation” of CVE-2025-48595 and characterizes it as an Android Framework issue, affecting devices running Android 14 or later, within a wider batch of fixes released this month. See their coverage here: Google fixes one actively exploited Android zero-day, 124 flaws.

What’s confirmed

The Android bulletin entry for CVE-2025-48595 states:

• The issue involves an integer overflow in multiple locations.
• Successful exploitation can lead to code execution and local escalation of privilege.
• No additional execution privileges are needed, and no user interaction is required.

Security patch levels of 2026-06-05 or later address all issues listed in the June bulletin. Google notes that corresponding source code patches are planned for release to AOSP shortly after the bulletin publication.

What’s still unclear

At the time of writing, technical details about the vulnerable code paths, proof-of-concept triggers, or affected subcomponents beyond the high‑level description have not been published in the bulletin. BleepingComputer’s report cites Google’s indication of limited, targeted exploitation, but specific attack chains and indicators of compromise are not publicly detailed. As with many Android vulnerabilities at disclosure time, that level of technical depth may follow in later updates to official advisories or source repositories.

Practical next steps

• Update to the latest security patch level available for your device. The June 2026 bulletin indicates that patch level 2026-06-05 includes all fixes for this cycle.
• Verify your patch level after updating. Google documents how to check this on Android devices here: Check and update your Android version.
• Monitor vendor advisories. Device makers often publish their own bulletins that map the Android patch level to device-specific firmware releases.

Closing thoughts

CVE-2025-48595 is a concise example of why timely Android updates matter: a low-interaction path to local privilege escalation is exactly the kind of building block attackers look for. While technical specifics are currently limited, the remediation path is clear. If your device supports the June 2026 update, applying patch level 2026-06-05 or later is the straightforward way to close this gap.
