CVE-2022-33730

Arbitrary code execution via missing boundary checks

Published Aug 5, 2022 · Updated Aug 3, 2024

A heap-based buffer overflow in Samsung DeX for PC on Android 12 allows physically proximate attackers to execute arbitrary code. The DeX for PC component processes attacker-controlled input without adequate boundary checks or input validation, causing a heap write beyond the allocated buffer. Physical access to a compatible Galaxy device and a DeX for PC connection are required; successful exploitation executes code on the device.
