CVE-2022-27813— Unconfigured memory protection modules in Motorola MTM5000

Quick assessment

Affected
Motorola Mobile Radio
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Motorola MTM5000是美国摩托罗拉（Motorola）公司的一种移动收音机。 Motorola MTM5000 存在安全漏洞，该漏洞源于缺乏对 OMAP-L138 ARM 和 DSP 内核之间共享页面的正确配置的内存保护，SoC 提供两个内存保护单元 MPU1 和 MPU2，以强制执行两个内核之间的信任边界，攻击者利用该漏洞可以控制其中一个核心，通过覆盖共享 RAM 或 DDR2 内存区域中的代码轻松获得另一个核心的代码执行权限。

Vulnerability Title
Unconfigured memory protection modules in Motorola MTM5000
Source: CVE Program / CVE List V5
Vulnerability Description
Motorola MTM5000 series firmwares lack properly configured memory protection of pages shared between the OMAP-L138 ARM and DSP cores. The SoC provides two memory protection units, MPU1 and MPU2, to enforce the trust boundary between the two cores. Since both units are left unconfigured by the firmwares, an adversary with control over either core can trivially gain code execution on the other, by overwriting code located in shared RAM or DDR2 memory regions.
