CVE-2025-20925
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 · uneditedOut-of-bounds read in applying binary of text data in Samsung Notes prior to version 4.4.26.71 allows local attackers to potentially read memory.
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 confidenceOut-of-bounds read vulnerability in Samsung Notes when processing binary text data allows a local attacker to read arbitrary memory contents due to insufficient bounds checking. The vulnerability exists in versions prior to 4.4.26.71.

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.
-
Verify Samsung Notes is installedCheck the device for the Samsung Notes app. On Android, this can be done via Settings > Apps > Samsung Notes, or by querying the package manager: `adb shell pm list packages | grep samsung.notes`Affected if Samsung Notes app is present on the device
-
Retrieve the installed version numberAccess the app info screen in Settings > Apps > Samsung Notes > App info, or use ADB: `adb shell dumpsys package com.samsung.android.app.notes | grep versionName`Affected if The command returns a versionName value that can be compared
-
Compare version against the vulnerable rangeIf the version number is available, compare the first three numeric components (4.4.26) against 4.4.26. Any version below 4.4.26.71 is within the vulnerable range. For example, 4.4.26.70, 4.4.25.x, or any earlier version is affectedAffected if The installed version is less than 4.4.26.71 (for example, 4.4.26.70, 4.4.25.10, 4.3.x, etc.)
If Samsung Notes is installed and the version is lower than 4.4.26.71, the device is vulnerable to the out-of-bounds read flaw when processing binary text data.
