CVE-2025-48595: Android Framework privilege escalation
Tech GuruQuick Answer
CISA added CVE-2025-48595 to its Known Exploited Vulnerabilities catalog on 2026-06-02, confirming that exploitation has occurred. If you operate Android Framework, identify the exact version and relevant configuration now, preserve security evidence, and follow the live vendor remediation. A KEV match does not prove your system was compromised, and installing an update does not rule out earlier exploitation.
Fix Or Immediate Action
What to do now: Install an OEM system update with Android security patch level 2026-06-01 or later; prefer the complete 2026-06-05 level or a later level and verify the date reported by the device.
Last verified: 2026-09-17 UTC. CISA KEV snapshot version
2026.09.16. Recheck the live advisory before changing production.
Context
Scope And Impact In Plain Language
Who should check: Anyone who manages Android Framework.
When this applies: Only when the exact product, version, and required configuration match the live vendor advisory. Owning the product family alone does not mean the device is vulnerable.
What could happen: Someone who already has the required foothold may be able to gain administrator, root, or Windows SYSTEM permissions—the highest level of control on the affected system.
Not sure? Find the product name and version in the device or application, then compare them with the affected-products section of the linked vendor notice.
Status At A Glance
| Product scope | Android — Framework |

| CVE | CVE-2025-48595 |
| TechGeeks response tier | P0 — confirm an exact match and act now |

| CVSS | 8.4 base — CVSS v3.1 — CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H — source: CISA ADP |
| Ransomware field | Unknown — this is not the same as No; CISA has not marked the field Known. |
| Forensic-triage field | No in the current CISA field; organizations should still investigate when exposure or evidence warrants it. |
| CWE | CWE-190 |
| Federal remediation date | 2026-06-05 — applies to covered federal agencies; other organizations should set a risk-based deadline. |
What Happened
Android Framework Integer Overflow Vulnerability. Android Framework contains an integer overflow vulnerability that allows for code execution that could allow for local privilege escalation. CISA's KEV listing confirms exploitation evidence, but it does not state how widespread the activity is or prove that any particular installation was compromised.
Affected Scope
Android Framework on Android 14, 15, 16, and 16-QPR2. This is an Android platform issue, not a Pixel-only or chipset-only issue.
Match the exact edition, hardware or virtual platform, release, patch level, enabled feature, and management exposure. A product-family name alone is not enough to establish applicability.
Steps
What To Do Now
- Confirm. Inventory every Framework asset and record its exact version, patch level, role, relevant configuration, and exposure.
- Preserve. Save UTC timestamps, off-device authentication, firewall, proxy, DNS, endpoint, application, and SIEM evidence before logs rotate or a disruptive change removes context.
- Contain. Restrict unnecessary internet and management-plane access using supported controls. Follow the live advisory: Open the live Android advisory.
- Remediate. Install an OEM system update with Android security patch level 2026-06-01 or later; prefer the complete 2026-06-05 level or a later level and verify the date reported by the device.
- Validate. Verify the resulting version or patch level, service health, logging, expected access, an expected denial, and representative dependent workflows.
- Escalate. If exposure overlapped the vulnerable period or evidence is suspicious, treat the system as a potential incident and follow vendor and incident-response recovery guidance.
Fixed Releases And Mitigation
Permanent Fix
Vendor-directed fix path: Install an OEM system update with Android security patch level 2026-06-01 or later; prefer the complete 2026-06-05 level or a later level and verify the date reported by the device.
Verified fixed release, patch level, or update guidance captured at the last check:
- Android security patch level 2026-06-01 or later
Workaround Or Temporary Mitigation
Android platform protections and Google Play Protect can make exploitation more difficult, but Google recommends updating to the latest Android version and security patch available for the device.
Important boundary: A workaround, access restriction, or provider-side control may reduce risk while the update is prepared, but it does not necessarily remove vulnerable code or erase an earlier compromise. Install the vendor-approved update when one is available.
Investigation And Recovery
CISA added this CVE to KEV. The June bulletin describes local privilege escalation with no additional execution privileges or user interaction; treat it as a possible exploit-chain component when investigating a suspected device compromise.
When an attacker may have gained administrative, root, SYSTEM, identity, management-plane, or code-execution access, patching alone is not an eradication claim. Preserve evidence, scope affected accounts and downstream systems, rotate exposed credentials or certificates when justified, and rebuild from a trusted source when vendor or incident-response guidance requires it.
Notes
Exploitation Evidence
Vendor statement: Google says there are indications of limited, targeted exploitation.
CISA statement: CVE-2025-48595 was added to KEV on 2026-06-02. The ransomware field is Unknown, and the forensic-triage field is No. These are separate signals.
Validation And Boundaries
This notice does not prove that every product carrying the family name is affected, that exploitation is widespread, that a clean indicator search rules out compromise, or that a successful update restored trust. TechGeeks has not reproduced the exploit and does not replace the vendor advisory, asset inventory, vulnerability scanner, or incident-response process.
