Concurrency Investigator Investigation

Investigate concurrency issues including race conditions, deadlocks, and thread safety violations.

Investigation Checklist

Race Condition Detection

• Identify shared mutable state accessed without synchronization
• Check for check-then-act patterns that allow interleaving
• Look for time-of-check to time-of-use (TOCTOU) vulnerabilities
• Verify atomic operations are used where required
• Detect read-modify-write sequences lacking proper guards

Deadlock Analysis

• Map lock acquisition order across all code paths
• Identify circular wait conditions between threads or resources
• Check for nested lock acquisitions that invert ordering
• Verify timeout mechanisms exist for lock acquisition
• Look for resource starvation caused by unfair scheduling
