Op-Tee CVE Vulnerabilities

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 double free. `shdr_verify_signature` used to verify

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 via electromagnetic fault injections.

OP-TEE Trusted OS is the secure side implementation of OP-TEE project, a Trusted Execution Environment. Versions prior to 3.19.0, contain an Improper Validation of Array Index vulnerability. The function `cleanup_shm_refs()` is called by both `entry_invoke_command()` and `entry_open_session()`. The

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 World can perform arbitrary memory read/write operat

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 involves a DMA capable peripheral.

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.

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: Buffer Overflow. The impact is: Code execution in the context of TEE core (kernel). 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: Execution of code in TEE core (kernel) context. 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: Code execution in context of TEE core (kernel). 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.

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: 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.

The rsa_verify_hash_ex function in rsa_verify_hash.c in LibTomCrypt, as used in OP-TEE before 2.2.0, does not validate that the message length is equal to the ASN.1 encoded data length, which makes it easier for remote attackers to forge RSA signatures or public certificates by leveraging a Bleichen
