Google’s June 2026 Android Security Bulletin, published 2 June, patches 124 vulnerabilities across the Android platform including CVE-2025-48595 — an integer overflow in the Android Framework that has been exploited in limited, targeted attacks. The exploitation pattern, characterised as “limited targeted exploitation” in the bulletin, is consistent with nation-state spyware or surveillance tool deployment against high-value individuals rather than mass exploitation.
CVE-2025-48595: Zero-Day Technical Details
CVE-2025-48595 is an integer overflow in the Android Framework component. The vulnerability allows local privilege escalation without requiring any user interaction — an attacker with code execution in a sandboxed process can exploit the integer overflow to gain elevated privileges within the Android runtime.
The vulnerability affects Android 14 and later. Google’s note of “limited targeted exploitation” and the 2025 CVE identifier (despite being patched in June 2026) indicate this was likely discovered and reported through threat intelligence channels rather than by Google’s own research — consistent with being weaponised by a commercial surveillance vendor or nation-state actor before responsible disclosure.
Severity: High (Android’s second-highest severity tier). No CVSS score published for Android-specific vulnerabilities.
Exploitation requirements: Local code execution in a sandboxed process (reachable via browser exploitation, malicious application, or message-based zero-click attack chains depending on the access method used to deliver the initial payload).
Scale of the June Bulletin
The 124 total vulnerabilities patched in June 2026 span:
- Framework: 18 vulnerabilities including CVE-2025-48595
- System: 28 vulnerabilities
- Kernel: 22 vulnerabilities
- Vendor components: 56 vulnerabilities across Qualcomm, MediaTek, ARM, and other chipset vendor components
The breadth reflects Android’s complex supply chain: vulnerabilities in vendor components require patches from chipset manufacturers in addition to Google’s own code. Samsung, Pixel, and AOSP builds receive the core Android patches; OEM-specific patches require OEM update releases.
Enterprise Patching Considerations
Pixel devices: Google Pixel devices receive June 2026 security updates through the standard over-the-air update mechanism. Enterprise Pixel fleets managed through Android Enterprise should receive the update through the management console within 1–2 days of publication.
Samsung Galaxy: Samsung typically releases its monthly security update 1–2 weeks after the Android Security Bulletin. Enterprise Galaxy fleets managed through Samsung Knox or a third-party EMM should track the Samsung update timeline separately.
Other Android OEMs: Update timelines vary significantly. Enterprise fleets running devices from OEMs with longer update timelines (some Motorola, TCL, or other OEMs) may not receive June 2026 patches for several weeks or may not receive them at all for older device models.
Android Enterprise management: For enterprise Android fleets managed through Microsoft Intune, VMware Workspace ONE, or other EMMs, configure automatic deployment of the June 2026 security update with a compliance deadline of 7 days from availability.
Recommended actions:
- Apply the June 2026 Android Security Update to all enterprise Android devices as a priority update (containing an actively exploited zero-day)
- For devices that cannot receive the update within 7 days due to OEM delays: assess whether they should be removed from enterprise access until updated
- Mobile Threat Defence (MTD) tools (CrowdStrike Falcon for Mobile, Lookout, Zimperium) should be queried for any detections consistent with CVE-2025-48595 exploitation targeting in the period before the patch was published
