Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In multiple locations, there is a possible lockscreen bypass due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A race condition in multiple locations allows bypassing the lockscreen authentication mechanism, enabling local privilege escalation without requiring user interaction or elevated privileges. The vulnerability stems from insufficient synchronization in the authentication flow that can be exploited by manipulating timing between operations.

MitigationApply proper synchronization primitives (locks, atomic operations, or mutexes) around all lockscreen authentication code paths identified as vulnerable to the race condition. Ensure all authentication state transitions are atomic and cannot be interrupted.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check Android version installed
    Navigate to Settings > About Phone > Android version, or run 'adb shell getprop ro.build.version.release'
    Affected if The device is running Android 14.0 or Android 15.0 exactly as listed in affected versions
  2. Verify lockscreen authentication is configured
    Check if a PIN, password, pattern, or biometric is set on the device via Settings > Security > Screen lock type
    Affected if A lockscreen authentication method is enabled - the race condition exploits the authentication flow when lockscreen protection is active
  3. Confirm device is not patched
    Check for the latest Android security patch level at Settings > About Phone > Security Patch Level, or run 'adb shell getprop ro.build.version.security_patch'
    Affected if The installed security patch level predates the fix for CVE-2025-48568 (patch date not specified in provided data, but version 14.0 and 15.0 are listed as affected)

The device is affected if it runs Android 14.0 or 15.0 and has any lockscreen authentication method enabled, as the race condition bypasses this protection mechanism.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply proper synchronization primitives (locks, atomic operations, or mutexes) around all lockscreen authentication code paths identified as vulnerable to the race condition. Ensure all authentication state transitions are atomic and cannot be interrupted.

Recommended fix High confidence

Android 16 (latest stable release) or May 2025 Android Security Patch Level

  1. Check for and install the latest Android security update for your device. Go to Settings > Security & privacy > Security update > Google Security Patch level (or similar path depending on device)
  2. Verify the installed patch level matches or exceeds the May 2025 Android Security Bulletin (or the latest available)
  3. If no update is available from your device manufacturer, consider upgrading to Android 16 if supported by your device, as it contains the fix for this vulnerability
  4. After updating, verify the lockscreen properly secures the device by testing that authentication is required to access the device
Caveat Android 16 may have UI/behavior changes compared to Android 14/15; verify app compatibility before full deployment in enterprise environments
