Android Framework CVE-2025-48595: KEV Local Privilege Escalation

Executive Summary

Google’s June 2026 Android Security Bulletin says there are indications that CVE-2025-48595 may be under limited, targeted exploitation. The Framework vulnerability can produce code execution through an integer overflow and lead to local privilege escalation without additional execution privileges or user interaction Google Android Security Bulletin.

CISA added the CVE to the Known Exploited Vulnerabilities catalog on 2026-06-02, with a federal remediation due date of 2026-06-05 CISA KEV. Android lists the issue as High severity and identifies Android 14, 15, 16, and 16 QPR2 as updated AOSP versions. Defenders should use the device’s security patch level, not the marketing OS version alone, to determine remediation status.

Impact Determination

Classification	Criteria	Required evidence	Required action
Confirmed compromise	Device forensics or vendor telemetry identifies exploitation tied to this CVE.	Preserved application inventory, security telemetry, crash artifacts, and vendor findings.	Isolate the device, revoke enterprise sessions, investigate the initial-access application, and re-enroll from a known-good state.
Presumed exposed	Android 14, 15, 16, or 16 QPR2 device has a patch level before 2026-06-01.	MDM-reported OS version and security patch level.	Apply an OEM update containing the 2026-06-01 Android security patch level or later.
Potentially exposed	Android version or patch level is missing or stale in inventory.	Current MDM or on-device patch data.	Block or restrict the device until patch state is verified.
Not exposed	Device reports the 2026-06-01 security patch level or later from its OEM.	Current device patch level and OEM bulletin coverage.	Record the evidence and continue normal mobile threat monitoring.

Timeline

• 2025-08 to 2026-01: Public AOSP commits associated with Android bug A-430889718 stage and select SQLite 3.44.5 for affected release branches.
• 2026-06-01: Google publishes the June 2026 Android Security Bulletin and notes limited, targeted exploitation.
• 2026-06-02: CISA adds CVE-2025-48595 to KEV with a 2026-06-05 due date.
• 2026-06-10: Sources and public patch references revalidated for this update.

Remediation and Closure

1. Enforce the 2026-06-01 security patch level or a later OEM build that includes the fix.
2. Prioritize devices permitted to sideload applications, handle privileged enterprise data, or lack current mobile threat-defense telemetry.
3. For suspected exploitation, preserve installed-package lists and available security telemetry before reset or re-enrollment.
4. Close the incident only when MDM reports a remediated build and any sessions available to a suspected compromised device have been revoked.
