| CVE-2023-41325 | 1 Linaro | 1 Op-tee | 2023-12-10 | N/A | 6.7 MEDIUM |
| 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 a TA binary before it is loaded. To verify a signature of it, allocate a memory for RSA key. RSA key allocate function (`sw_crypto_acipher_alloc_rsa_public_key`) will try to allocate a memory (which is optee’s heap memory). RSA key is consist of exponent and modulus (represent as variable `e`, `n`) and it allocation is not atomic way, so it may succeed in `e` but fail in `n`. In this case sw_crypto_acipher_alloc_rsa_public_key` will free on `e` and return as it is failed but variable ‘e’ is remained as already freed memory address . `shdr_verify_signature` will free again that memory (which is `e`) even it is freed when it failed allocate RSA key. A patch is available in version 3.22. No known workarounds are available. | |||||
| CVE-2022-47549 | 1 Linaro | 1 Op-tee | 2023-12-10 | N/A | 6.4 MEDIUM |
| 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. | |||||
| CVE-2021-36133 | 2 Linaro, Nxp | 7 Op-tee, I.mx6sx, I.mx 6 and 4 more | 2023-12-10 | 3.6 LOW | 7.1 HIGH |
| 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. | |||||
| CVE-2021-44149 | 2 Linaro, Nxp | 2 Op-tee, I.mx 6ultralite | 2023-12-10 | 4.6 MEDIUM | 7.8 HIGH |
| 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 operations on Secure World memory. This involves a v cycle. | |||||
| CVE-2019-25052 | 1 Linaro | 1 Op-tee | 2023-12-10 | 6.4 MEDIUM | 9.1 CRITICAL |
| 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. | |||||
| CVE-2020-13799 | 2 Linaro, Westerndigital | 7 Op-tee, Inand Cl Em132, Inand Cl Em132 Firmware and 4 more | 2023-12-10 | 4.6 MEDIUM | 6.8 MEDIUM |
| 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 specified by industry standards bodies and is implemented by storage devices from multiple vendors to assist host systems in securing trusted firmware. Several scenarios have been identified in which the RPMB state may be affected by an attacker without the knowledge of the trusted component that uses the RPMB feature. | |||||
