Op Tee

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. Rated high severity (CVSS 7.4), this vulnerability is low attack complexity. Public exploit code available.

An unprotected memory-access operation in optee_os in TrustedFirmware Open Portable Trusted Execution Environment (OP-TEE) before 3.20 allows a physically proximate adversary to bypass signature. Rated medium severity (CVSS 6.4), this vulnerability is no authentication required. Public exploit code available and no vendor patch available.

OP-TEE Trusted OS is the secure side implementation of OP-TEE project, a Trusted Execution Environment. Rated high severity (CVSS 8.2), this vulnerability is low attack complexity. Public exploit code available.

An issue was discovered in Trusted Firmware OP-TEE Trusted OS through 3.15.0. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.

The OPTEE-OS CSU driver for NXP i.MX SoC devices lacks security access configuration for several models, resulting in TrustZone bypass because the NonSecure World can perform arbitrary memory. Rated high severity (CVSS 7.1), this vulnerability is low attack complexity. No vendor patch available.

In Linaro OP-TEE before 3.7.0, by using inconsistent or malformed data, it is possible to call update and final cryptographic functions directly, causing a crash that could leak sensitive information. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity.

Western Digital has identified a security vulnerability in the Replay Protected Memory Block (RPMB) protocol as specified in multiple standards for storage device interfaces, including all versions. Rated medium severity (CVSS 6.8), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
