race-conditions

What problem does it solve?

Race conditions occur when multiple processes access and manipulate shared data concurrently, leading to security vulnerabilities such as data corruption, privilege escalation, or bypass of security controls. This skill covers detection, mitigation, and testing methodologies for TOCTOU and other race conditions.

Core Features & Use Cases

• Detection & Mitigation: Identify timing windows and non-atomic code paths; implement atomic operations and locking.
• Testing Scenarios: Validate resilience with concurrent requests and simulated races across critical paths.
• Use Case: For a multi-service system, ensure user privilege checks and shared resources are updated atomically to prevent privilege escalation.

Quick Start

Run a lightweight assessment against concurrent code paths to reveal TOCTOU or race-condition vulnerabilities.
