CVE-2024-56427Network attack vector

Memory corruption via unchecked RRC packet length

Published May 14, 2025 · Updated May 27, 2025

Out-of-bounds access in Samsung Exynos processors and modems allows remote attackers to corrupt memory via malformed RRC packets. The undisclosed RRC packet-processing path performs a write without checking the supplied packet length, reaching memory beyond the intended bounds. No authentication or user interaction is required, but the affected chipset must receive crafted radio-control traffic; public sources do not specify the resulting device behavior.
