CVE-2025-48544: 
NixOS vulnerability analysis and mitigation

CVE-2025-48544 is a SQL injection vulnerability in Android's MediaProvider component that allows a local attacker to read files belonging to other apps, leading to local escalation of privilege. It affects Android versions 13.0, 14.0, 15.0, and 16.0. The vulnerability was disclosed in the Android September 2025 Security Bulletin (published September 4, 2025) and carries a CVSS v3.1 base score of 7.8 (High) (Android Security Bulletin). No user interaction is required for exploitation, and no additional execution privileges beyond low-level local access are needed.

The vulnerability is classified as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command — SQL Injection), residing in multiple locations within Android's MediaProvider package. An attacker with local, low-privilege access can craft malicious SQL input that is not properly sanitized, enabling unauthorized access to files owned by other applications (Android Security Bulletin, Android Source Patch). The attack vector is local with low attack complexity, and the fix is available in the referenced MediaProvider commit. The advisory also notes the most severe vulnerability in the same section could lead to remote (proximal/adjacent) code execution, though CVE-2025-48544 itself is specifically described as a local privilege escalation via file read.

Successful exploitation allows a local attacker with low privileges to read files belonging to other applications on the affected Android device, resulting in high confidentiality, integrity, and availability impact per the CVSS scoring (Android Security Bulletin). This could expose sensitive user data stored by other apps, such as credentials, personal documents, or application-specific files. In the broader context of the September 2025 bulletin, the vulnerability class is associated with potential remote (proximal/adjacent) code execution scenarios (CIS Advisory).

There is no public proof-of-concept exploit and no evidence of in-the-wild exploitation at this time (Android Security Bulletin). The EPSS score is approximately 0.006%, reflecting a very low probability of exploitation in the near term. CVE-2025-48544 is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Exploitation requires local access with low privileges and no user interaction, making it more accessible to malicious apps already installed on a device.

Apply the Android September 2025 Security Bulletin patches (security patch level 2025-09-01 or later) for Android 13, 14, 15, and 16, which include the fix for CVE-2025-48544 (Android Security Bulletin). Additional follow-up patches were included in the March 2026 Android Security Bulletin (Android March 2026 Bulletin). Device manufacturers such as Samsung have incorporated these fixes into their September 2025 and March 2026 security updates. Users should ensure their devices are updated to the latest available security patch level from their device vendor.

The CIS (Center for Internet Security) issued an advisory noting that multiple vulnerabilities in the September 2025 Android OS update, including CVE-2025-48544, could allow for remote code execution (CIS Advisory). Samsung and other OEMs incorporated the patch into their September 2025 security updates, with coverage noted by device-focused outlets (SammyFans). The vulnerability appeared in community CVE tracking discussions on Reddit's r/CVEWatch as part of trending CVE roundups in September 2025, indicating moderate community awareness.
