Security Summary
CVE-2025-20917 is an out-of-bounds read vulnerability (CWE-125) in the Samsung Notes application, affecting versions prior to 4.4.26.71. The flaw occurs when applying binary data from PDF content, enabling attackers to access memory outside intended bounds. It carries a CVSS v3.1 base score of 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), rated as medium severity due to its local attack vector and high confidentiality impact.
A local attacker with low privileges on the device can exploit this vulnerability without user interaction or high complexity. Successful exploitation allows reading sensitive out-of-bounds memory, potentially exposing confidential information such as other processes' data or user credentials stored in memory.
