CVE-2025-48653: 
NixOS vulnerability analysis and mitigation

CVE-2025-48653 is a local privilege escalation vulnerability in Google Android affecting the loadDataAndPostValue function across multiple files. A logic error in the code allows a malicious application to obscure its permission usage, enabling local escalation of privilege. Affected versions include Android 14, 15, 16, and 16 QPR2 (including beta releases). The vulnerability was disclosed on March 2, 2026, as part of Google's March 2026 Android Security Bulletin. It carries a CVSS v3.1 base score of 7.8 (High) (Android Security Bulletin, Red Hat CVE).

The root cause is classified as CWE-693 (Protection Mechanism Failure), stemming from a logic error in the loadDataAndPostValue function present in multiple Android framework files. This flaw allows an attacker to obscure how permissions are being used by an application, effectively bypassing Android's permission enforcement mechanisms. The attack vector is local, requires only low privileges (e.g., a standard installed app), and does not require any user interaction, making it particularly stealthy. No public proof-of-concept code has been identified at this time (Android Security Bulletin, Red Hat CVE).

Successful exploitation grants an attacker high confidentiality, integrity, and availability impact on the affected device, effectively achieving full local privilege escalation without requiring elevated starting privileges or user interaction. A malicious app could silently access sensitive data, modify system state, or disrupt device availability while hiding its permission usage from the user and the system. This could facilitate further lateral movement within the device ecosystem or serve as a stepping stone in a broader attack chain (Android Security Bulletin).

There is no known public exploit code or evidence of in-the-wild exploitation for CVE-2025-48653 at this time. The EPSS score is extremely low at approximately 0.009%, indicating a low near-term probability of exploitation (Feedly). The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Qualys scanners have detection signatures for this CVE (detection IDs 610761 and 610767), indicating it is being tracked by vulnerability management platforms (Feedly).

Google addressed CVE-2025-48653 in the March 2026 Android Security Bulletin (patch level 2026-03-01). Users and administrators should apply the March 2026 security patch to all affected Android 14, 15, and 16 devices as soon as it is available from their device manufacturer. Samsung has also incorporated this fix in its March 2026 security patch (Android Security Bulletin, SammyFans). No configuration-based workarounds have been published; patching is the recommended remediation.

The CIS published an advisory noting multiple vulnerabilities in the March 2026 Android OS update, including CVE-2025-48653, highlighting the potential for privilege escalation (CIS Advisory). GrapheneOS incorporated the relevant fixes in its December 2025 and subsequent releases, reflecting the project's proactive security patching approach (GrapheneOS). Community and media coverage has been routine, with no exceptional researcher commentary or widespread alarm noted.
