Title

Trusted Firmware M存在未明漏洞

Description

ARM Trusted Firmware M（TFM）是英国ARM公司的一个开源软件。提供了一组高度可配置的软件组件，以创建受信任的执行环境。 Trusted Firmware OP-TEE Trusted OS 3.15.0之前版本中存在安全漏洞，该漏洞源于NXP i.MX6UL SoC设备的OPTEE-OS CSU驱动程序缺少唤醒相关寄存器的安全访问配置，导致 TrustZone 绕过，攻击者可利用该漏洞通过NonSecure World可以对Secure World内存执行任意内存读/写操作。

CVE-2021-44149 (GCVE-0-2021-44149)

Vulnerability from cvelistv5 – Published: 2021-12-07 20:59 – Updated: 2024-08-04 04:17

Summary

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.

Severity
