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. Starting in version 3.10.0 and prior to version 4.11.0, an unbounded recursion can crash the PKCS#11 TA. Version 4.11.0 contains a patch. No known workarounds are available.
