Unconfigured memory protection modules in Motorola MTM5000

CVE-2022-27813

Summary

Motorola MTM5000 series firmware is affected by a significant memory protection vulnerability where the configuration of memory protection units between the OMAP-L138 ARM and DSP cores is incomplete. This oversight allows an adversary who gains control over one core to exploit shared RAM or DDR2 memory regions, ultimately leading to unauthorized code execution on the other core. Proper configuration of these protections is essential to maintaining the integrity and security of the system against potential breaches.
