Race condition detection in concurrent processing identifies read-modify-write conflicts and TOCTOU issues across databases, file systems, and in-memory counters. Scanning flags non-atomic operations and missing transactional safeguards like SELECT FOR UPDATE that cause inconsistent states under concurrent access.

To scan web services for race conditions, analyze concurrent request paths targeting databases, file systems, and in-memory stores. The scan identifies read-modify-write races and TOCTOU issues, reporting CWE-362 vulnerabilities and providing remediation guidance using atomic operations and SELECT FOR UPDATE transactions.

Fixing a TOCTOU vulnerability requires implementing atomic operations, proper locking, and database transactions with SELECT FOR UPDATE. These safeguards ensure concurrent requests modify shared data safely, eliminating read-modify-write races and resolving reported CWE-362 vulnerability findings.

Race condition scanning applies to in-memory counters, file systems, and databases. It detects non-atomic counters and missing transactional safeguards across these systems under concurrent access, identifying exploitable TOCTOU issues and read-modify-write races for remediation.

Limitations of race condition scanning include the difficulty of detecting timing-dependent errors without concurrent load. While static analysis identifies missing locks and non-atomic counters, verifying exploitable states and confirming fixes requires dynamic testing of concurrent requests.
