CVE-2025-54328Public exploitNetwork attack vector

Memory corruption via SMS RP-DATA parsing

Published Apr 6, 2026 · Updated Apr 6, 2026

Stack-based buffer overflow in Samsung Exynos SMS parsing allows remote attackers to corrupt memory through RP-DATA messages. The SMS component writes RP-DATA input beyond a stack buffer, but Samsung has not disclosed the affected function or malformed field. Network delivery requires no privileges or user interaction and can compromise data integrity and interrupt cellular service.
