CVE-2025-48552: 
NixOS vulnerability analysis and mitigation

CVE-2025-48552 is a local privilege escalation vulnerability in Android's DevicePolicyManagerService.java, specifically within the saveGlobalProxyLocked method. A logic error in the code can cause desynchronization from persistence, enabling a local attacker to escalate privileges without requiring additional execution privileges or user interaction. Affected versions include Android 13, 14, 15, and 16. It carries a CVSS v3.1 base score of 7.8 (High) (Android Security Bulletin).

The root cause is a logic error (CWE-670: Always-Incorrect Control Flow Implementation) in the saveGlobalProxyLocked method of DevicePolicyManagerService.java, which can cause the device's global proxy setting to become desynced from its persisted state. This desynchronization can be leveraged by a local attacker with low privileges to manipulate device policy state in unintended ways, ultimately achieving privilege escalation. The attack vector is local, requires only low privileges, and no user interaction is needed. A patch commit is available in the Android platform frameworks/base repository (Android Security Bulletin).

Successful exploitation allows a local attacker to escalate privileges on the affected Android device, potentially gaining elevated access to sensitive system functions and data. The vulnerability impacts confidentiality, integrity, and availability — all rated High — meaning an attacker could read sensitive data, modify system settings, or disrupt device operation. Affected devices running Android 13, 14, 15, or 16 are at risk (Android Security Bulletin).

Google addressed CVE-2025-48552 in the Android Security Bulletin dated September 1, 2025. Users and administrators should apply the September 2025 Android security patch level (2025-09-01) or later to all affected devices running Android 13, 14, 15, or 16. Samsung and other OEM vendors have incorporated this fix into their September 2025 security updates. No configuration-based workaround is available; patching is the only remediation (Android Security Bulletin).

The September 2025 Android Security Bulletin received coverage from security news outlets and OEM vendors. Samsung announced its September 2025 security update incorporating this and other fixes for Galaxy devices. The CIS also issued an advisory noting multiple vulnerabilities in Google Android OS addressed in this bulletin (CIS Advisory, Samsung Coverage).
