Google Patches 124 Vulnerabilities in June 2026 Android Update, Including Exploited Zero-Day CVE-2025-48595

Google has rolled out its June 2026 Android security update, addressing a total of 124 vulnerabilities, among which is a critical zero-day exploit identified as CVE-2025-48595. This integer overflow vulnerability resides within the Android Framework, allowing local attackers to escalate their privileges on affected devices without any user interaction.

Understanding CVE-2025-48595

CVE-2025-48595 is classified as a high-severity integer overflow vulnerability (CWE-190) within the Android Framework, which comprises the APIs and system services that applications directly utilize. Integer overflow occurs when an arithmetic operation generates a value that surpasses the maximum limit of the data type used to store it. This can lead to unexpected behaviors that attackers can exploit to gain elevated access.

The vulnerability permits a local attacker, equipped with basic application permissions, to escalate privileges and execute code at a higher permission level. This could potentially grant them full control over device functionalities. Notably, exploitation of this vulnerability requires only the execution of a malicious application on the device, with no further user interaction needed.

Context of the Vulnerability

This incident marks the fourth Android zero-day vulnerability patched since December 2025. Google has indicated that CVE-2025-48595 “may be under limited, targeted exploitation.” This terminology is typically employed when targeted attacks have been confirmed, although widespread exploitation in the wild has not yet been documented. Such patterns are often linked to commercial spyware vendors or nation-state actors targeting high-profile individuals, including journalists, activists, and government officials.

Scope of the June 2026 Update

The June 2026 Android security update is comprehensive, addressing 124 vulnerabilities across two patch levels. Patch level 2026-06-01 focuses on core Android OS components, including the Framework and System, with 18 vulnerabilities rated as critical. Patch level 2026-06-05 encompasses all fixes from the earlier patch level and adds further patches for kernel subcomponents and third-party chipset drivers from manufacturers such as Qualcomm and MediaTek.

Affected Android versions include Android 14, 15, 16, and Android 16 QPR2. Pixel devices receive updates immediately through Google’s update delivery system, while devices from manufacturers like Samsung, OnePlus, and Xiaomi will receive updates on a staggered timeline that may extend for weeks or months following Google’s release.

Technical Details and CVSS

• CVE: CVE-2025-48595
• CWE: CWE-190 (Integer Overflow or Wraparound)
• Severity: High
• KEV Status: Not confirmed; added to CISA KEV catalogue as of June 3, 2026
• Affected Versions: Android 14, Android 15, Android 16, Android 16 QPR2

Implications of the Update

The emergence of four Android zero-day vulnerabilities within a span of six months underscores an active market for Android exploits among sophisticated threat actors. While Google’s characterization of “limited, targeted exploitation” suggests that mass exploitation is not yet a concern, the targeted use of these vulnerabilities by spyware operators or nation-state actors poses significant risks for high-value individuals and organizations.

Mobile devices increasingly serve as primary work tools, accessing corporate email, VPNs, and sensitive business applications. A privilege escalation vulnerability on a corporate-enrolled Android device could enable an attacker to capture credentials, intercept multi-factor authentication codes, access enterprise applications, and exfiltrate sensitive data—all from a device that users typically trust.

The trajectory of Android zero-days in 2026 indicates that mobile endpoints are garnering heightened attention from sophisticated threat actors. Analysts emphasize that organizations with mobile device management (MDM) programs should prioritize Android OS updates with the same urgency as Windows Patch Tuesday releases.

Recommended Mitigation Steps

Organizations are advised to take immediate action to mitigate the risks associated with this vulnerability:

• Apply the June 2026 Android security update promptly on all managed Android devices via MDM or enterprise mobility management (EMM) platforms.
• For Pixel devices, install the update via Settings > System > Software update.
• Contact device manufacturers for updated timelines if using non-Pixel Android devices.
• Implement mobile application management (MAM) policies that restrict the installation of applications from unverified sources.
• Enable Google Play Protect scanning on all managed Android devices.
• Enforce policies that restrict sensitive corporate applications to devices meeting a minimum patch level of 2026-06-05 through MDM.
• Monitor for unusual privilege escalation events in your mobile device management console.

The June 2026 Android update highlights that mobile patch management is now a critical component of enterprise security hygiene, rather than an optional maintenance task.
