Name of the Vulnerable Software and Affected Versions: Samsung Notes versions prior to 4.3.02.61

Description: The issue is related to a lack of boundary checking of a buffer in the libSPenBase library, which allows an out-of-bounds (OOB) read. This can potentially lead to information disclosure or other security issues.

Recommendations: For versions prior to 4.3.02.61, update to version 4.3.02.61 or later to resolve the issue. As a temporary workaround, consider restricting access to the libSPenBase library until a patch is applied.
