CVE-2023-42557

Local code execution via out-of-bounds write

Published Dec 5, 2023 · Updated Aug 2, 2024

Out-of-bounds write in libIfaaCa in Samsung Mobile Devices on Android 12 through 14 allows local system attackers to execute arbitrary code. Samsung identifies libIfaaCa as the faulty locus but has not published the input path, function, or incorrect bounds operation that causes the write. Exploitation requires local access with system privileges and no user interaction; successful exploitation runs code and can alter data or interrupt the device.
