High Known exploited (KEV) CVE-2025-48595

Integer overflow in the Android Framework (CVE-2025-48595) — local privilege escalation

Android Framework Added to KEV Jun 2, 2026 Federal remediation due 2026-06-05

An integer-overflow vulnerability in Android's core "Framework" component leads, via code execution, to local privilege escalation. Fixed in the June 2026 Android security update. CISA listed it as known-exploited (KEV) (CVSS 8.4 High).

Key facts

  • CVE IDCVE-2025-48595
  • CVSS base score8.4 HIGH
  • CVSS vectorCVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
  • Affected (vendor / product)Android Framework
  • CWECWE-190
  • ExploitationListed in CISA KEV (exploitation confirmed)
  • Remediation due2026-06-05 (U.S. federal civilian agencies, BOD 22-01)

Key points

  • Integer overflow (CWE-190) in the Android Framework (the OS foundation layer)
  • Leads to local privilege escalation via code execution
  • Fixed in the June 2026 Android security bulletin. Listed in CISA KEV (CVSS 8.4 High)
  • Response: update the device security patch level to 2026-06-01 or later
  • Federal civilian remediation deadline was June 5, 2026
  • Local privilege escalation cannot reach a device alone, but completes control when combined with another vulnerability.

1The Android Framework component

CVE-2025-48595 is an integer-overflow vulnerability (CWE-190) in Android's core "Framework" component (the layer bridging apps and the OS). Integer overflow causes inconsistencies in memory handling, and using that as a foothold for code execution enables local privilege escalation (obtaining higher privileges) on the device.

2What local privilege escalation means

Local privilege escalation does not by itself allow remote intrusion, but combined with a malicious app or another vulnerability it is often abused as the "final push" that lets an attacker take deep control of a device. It was added to CISA's KEV catalog on June 2, 2026, with exploitation confirmed in the wild.

3No way in on its own, but the last push

Local privilege escalation is not a vulnerability that lets anyone in remotely by itself. Within the assembly of an attack, though, it works as the decisive piece.

A vulnerability allowing remote entryLocal privilege escalation (this record)
The attack completes on its ownOn its own it cannot reach the device
Blocking external reach is the countermeasureUsed in combination with a malicious app or another vulnerability
Used as the way inUsed as the last push that completes control
Narrowing exposure reduces the impactOnly an update on the device closes it

An integer overflow produces an inconsistency in memory handling, and code execution built on that yields higher privilege on the device. The fix ships in Google's Android Security Bulletin for June 2026; bringing the device security patch level to 2026-06-01 or later is the basic response.

Why it matters

For organizations managing many corporate Android devices, the priorities are visibility into patch status and updating. In BYOD environments, it is a prompt to enforce a minimum patch level by policy.

FAQ

What is local privilege escalation?
An attack in which a process already running on a device (e.g. a malicious app) seizes higher privileges than it should have. It differs from standalone remote intrusion but becomes serious when combined with other weaknesses.
What should I do?
Update the Android security patch to the latest (2026-06-01 or later). In organizations, verifying patch status via MDM is effective.
