Linaro ≫ 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. Starting in version 3.20 and prior to version 3.22, `shdr_verify_signature` can make a d...

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 verification and install malicious trusted applications...

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 read/write operations on Secure World memory. This involve...

An issue was discovered in Trusted Firmware OP-TEE Trusted OS through 3.15.0. The OPTEE-OS CSU driver for NXP i.MX6UL SoC devices lacks security access configuration for wakeup-related registers, resulting in TrustZone bypass because the NonSecure Wo...

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.

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 of eMMC, UFS, and NVMe. The RPMB protocol is specifi...

Linaro/OP-TEE OP-TEE Prior to version v3.4.0 is affected by: Boundary checks. The impact is: This could lead to corruption of any memory which the TA can access. The component is: optee_os. The fixed version is: v3.4.0.

Linaro/OP-TEE OP-TEE 3.3.0 and earlier is affected by: Boundary crossing. The impact is: Memory corruption of the TEE itself. The component is: optee_os. The fixed version is: 3.4.0 and later.

Linaro/OP-TEE OP-TEE 3.3.0 and earlier is affected by: Rounding error. The impact is: Potentially leaking code and/or data from previous Trusted Application. The component is: optee_os. The fixed version is: 3.4.0 and later.

Linaro/OP-TEE OP-TEE 3.3.0 and earlier is affected by: Buffer Overflow. The impact is: Memory corruption and disclosure of memory content. The component is: optee_os. The fixed version is: 3.4.0 and later.
