Description

The vulnerability allows a malicious application to escalate privileges on the system.

The vulnerability exists due to a boundary error in MCS. A malicious application can pass a specially crafted number of GPIOs configured in an internal parameters array, trigger a stack-based buffer overflow and execute arbitrary code.

Mitigation
Install updates from vendor's website.
