CVE-2025-47202Network attack vector

Out-of-bounds write via unchecked RRC input length

Published Jul 7, 2025 · Updated Jul 8, 2025

Out-of-bounds write in Samsung Exynos RRC allows remote attackers to corrupt memory via unspecified network input. The RRC component performs a write without first validating the input length, allowing data to cross the intended buffer boundary. No privileges or user interaction are required; public sources report confidentiality and availability impact but do not disclose whether exploitation causes a crash, code execution, or another concrete outcome.
