CVE-2025-48568: 
NixOS vulnerability analysis and mitigation

CVE-2025-48568 is a lockscreen bypass vulnerability in Google Android caused by a race condition in multiple locations within the OS. It affects Android versions 14.0 and 15.0, and allows a local attacker to bypass the device lockscreen without requiring any additional privileges or user interaction. The vulnerability was published on March 2, 2026, with a patch included in the Android March 2026 security bulletin. It carries a CVSS v3.1 base score of 7.4 (High) (Android Bulletin, Red Hat CVE).

The root cause is classified as CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization — Race Condition). The vulnerability exists in multiple locations within the Android lockscreen implementation, where a timing window allows an attacker to bypass the lock mechanism by exploiting a race condition between concurrent operations. Exploitation requires local (physical) access to the device but no privileges, and no user interaction is needed. The attack complexity is rated High, reflecting the need to win a specific timing race (Android Bulletin, Red Hat CVE).

Successful exploitation allows a local, unprivileged attacker to bypass the Android lockscreen and gain full control of the affected device. This results in high confidentiality, integrity, and availability impact — the attacker can read, modify, or delete all user data, install malicious applications, and access sensitive accounts and credentials stored on the device. The scope is limited to the compromised device, but the data exposure risk is significant given the personal and potentially corporate data typically stored on Android devices (Android Bulletin).

There is no public proof-of-concept exploit available, and no evidence of in-the-wild exploitation has been reported as of the time of publication (Red Hat CVE). The EPSS score is extremely low at 0.00002, reflecting minimal current exploitation probability. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Exploitation requires physical access to the device and the ability to reliably trigger a race condition, which limits the practical attacker pool.

1. Physical Access: Obtain physical access to a target Android 14.0 or 15.0 device that is locked with a PIN, pattern, or password.
2. Trigger Race Condition: Interact with the device in a manner that triggers the race condition in the lockscreen implementation — this may involve rapidly performing specific actions (e.g., incoming calls, notifications, or other system events) that cause concurrent execution paths in the lockscreen code.
3. Win the Race: Time the interactions so that the lockscreen check and the unlock action occur in a window where the synchronization flaw allows the check to be bypassed.
4. Gain Unauthorized Access: Upon successfully exploiting the race condition, the lockscreen is bypassed and the attacker gains full access to the device and all its data without needing the correct credentials (Android Bulletin).

Google released a patch for CVE-2025-48568 in the Android Security Bulletin for March 2026 (patch level 2026-03-01), published on March 2, 2026. Users and administrators should update affected Android 14.0 and 15.0 devices to the patched security patch level as soon as possible (Android Bulletin). As a workaround until patching is possible, organizations should restrict physical access to devices and consider enabling remote device management (MDM) policies. Samsung and Huawei have also incorporated this fix into their respective security updates (CIS Advisory).

The CIS (Center for Internet Security) issued an advisory noting multiple vulnerabilities in the March 2026 Android bulletin, including CVE-2025-48568, and flagged the potential for privilege escalation (CIS Advisory). Samsung and Huawei both incorporated the fix into their own security bulletins, indicating broad OEM awareness and response (Huawei Bulletin). No significant independent researcher commentary or social media discussion has been identified for this CVE.
