Local code execution via HDCP trustlet overflow
Published Oct 4, 2023 · Updated Aug 2, 2024
Stack-based buffer overflow in the HDCP trustlet in Samsung Mobile Devices Android 12 and 13 allows local privileged attackers to execute code. The trustlet performs an insufficient size check on supplied input, allowing data to overflow a stack buffer. Exploitation requires privileged local access on an affected Samsung device and can execute attacker-controlled code in the trustlet context.
