Memory Race Condition
Overview
Memory race conditions occur when two threads access shared memory simultaneously without synchronization, and at least one access is a write. This leads to:
- Data corruption (non-deterministic results)
- Security bypass (auth state race)
- Potential exploitation via crafted timing
Remediation
- Use mutex/lock primitives for all shared data access
- Use atomic operations for simple counters and flags
- Design for lock-free or copy-on-write patterns where performance matters
- Use Go race detector:
go test -race
