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 own binary with textbox in Samsung Notes prior to version 4.4.21.62 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 confidenceAn out-of-bounds read vulnerability exists in Samsung Notes versions prior to 4.4.21.62. The vulnerability is triggered when processing a maliciously crafted note containing a textbox with specially constructed binary data, allowing a local attacker to read arbitrary memory contents.

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 Samsung Notes versionOpen the Google Play Store app, search for Samsung Notes, and view the version number in the app listing. Alternatively, go to Settings > Apps > Samsung Notes to see the installed version.Affected if The installed version is lower than 4.4.21.62 (e.g., 4.4.21.50, 4.4.20.15, etc.)
-
Confirm note editing feature is usedVerify that Samsung Notes is actively used for creating or editing notes, particularly notes containing textboxes or embedded objects.Affected if Samsung Notes is used to edit notes with textbox elements, as this is the vulnerable code path
-
Check for suspicious notesReview existing notes in Samsung Notes for any unexpected or unfamiliar notes containing textboxes with binary content, which could indicate exploitation attempts.Affected if Unknown or suspicious notes with textboxes containing unusual binary data are present on the device
A user is affected if their Samsung Notes version is below 4.4.21.62 and they create or edit notes with textboxes, as the vulnerability is triggered during processing of maliciously crafted note content.
