CWE-1298

Hardware Logic Contains Race Conditions

High

Description

A race condition in the hardware logic results in undermining security guarantees of the system.

Potential Impact

How to Fix

Architecture and Design

Adopting design practices that encourage designers to recognize and eliminate race conditions, such as Karnaugh maps, could result in the decrease in occurrences of race conditions.

Implementation

Logic redundancy can be implemented along security critical paths to prevent race conditions. To avoid metastability, it is a good practice in general to default to a secure state in which access is not given to untrusted agents.
