CVE-2025-21076
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.

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 confidenceThis is a local privilege escalation vulnerability in Samsung Account where improper permission handling allows a local attacker to access data in the Samsung Account application. The vulnerability requires user interaction to trigger, indicating it likely involves social engineering or tricking the user into performing an action that exposes data due to the flawed permission check.

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 if Samsung Account is installedNavigate to Settings > Apps on your Android device and search for Samsung Account, or check the app drawer for the Samsung Account iconAffected if Samsung Account app is present on the device
-
Determine the installed version of Samsung AccountIn Settings > Apps > Samsung Account, tap on App Info or About to view the version number (typically displayed as something like XX.XX.XX.XX)Affected if The version shown is less than 15.5.00.18 (for example, 15.5.00.17 or any earlier version)
-
Verify app permissions granted to Samsung AccountIn Settings > Apps > Samsung Account > Permissions, review which permissions are enabled. Check for any unusual or excessive permissions that were not intentionally grantedAffected if The app holds permissions that appear unnecessary for normal operation or were not explicitly authorized by you
You are affected if Samsung Account is installed and its version number is lower than 15.5.00.18, as this indicates the vulnerable version with the improper permission handling flaw.
