CVE-2025-48634
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 · uneditedIn relayoutWindow of WindowManagerService.java, there is a possible tapjack attack due to a missing permission check. 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 · high confidenceA missing permission check in the relayoutWindow method of Android's WindowManagerService allows a local attacker to perform a tapjacking attack, potentially overlaying windows to intercept user inputs and achieve local privilege escalation without requiring user interaction.

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 checksWork through these to decide whether this CVE applies to you.
-
Check Android versionRun 'adb shell getprop ro.build.version.release' or check Settings > About Phone > Android versionAffected if The version returned is 14.0, 15.0, or 16.0 exactly
-
Check security patch levelRun 'adb shell getprop ro.build.version.security_patch' to see if the vendor patch has been appliedAffected if The security patch level is earlier than the vendor fix date for CVE-2025-48634, or the field is empty on affected versions
-
Verify WindowManagerService accessibilityExamine the WindowManagerService binary or framework JAR in /system/framework/ for the relayoutWindow method signature and presence of permission enforcement codeAffected if The relayoutWindow method lacks permission validation checks for the FLAG_WINDOW_IS_PARTIAL/overlay window operations
-
Confirm overlay permission configurationCheck if apps can request SYSTEM_ALERT_WINDOW permission (Settings > Apps > Special access > Display over other apps). On affected versions, this combined with the missing check enables the tapjacking vector.Affected if Apps can be granted overlay permissions and the Android version is one of the affected builds
A device is affected if it runs Android 14.0, 15.0, or 16.0 and has not received the vendor security patch for CVE-2025-48634, which adds permission validation to WindowManagerService.relayoutWindow.
