OP-TEE is a Trusted Execution Environment (TEE) designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. In version 4.5.0, using a specially crafted tee-supplicant binary running in REE userspace, an attacker can trigger a panic in a TA that uses the libutee Secure Storage API. Many functions in libutee, specifically those which make up the Secure Storage API, will panic if a system call returns an unexpected return code. This behavior is mandated by the TEE Internal Core API specification. However, in OP-TEE’s implementation, return cod
