CRE-2025-0072 Critical Impact: 10/10 Mitigation: 7/10	Redis Out-Of-Memory → Persistence Crash → Replica/ACL Write Failures	Detects a cascade of critical Redis failure modes in a single session: - Redis refuses writes when maxmemory is exceeded (OOM). - RDB snapshot (BGSAVE) fails (MISCONF) due to simulated full-disk. - Replica refuses writes (READONLY). - ACL denies a write (NOPERM).

CRE-2025-0176 Critical Impact: 9/10 Mitigation: 7/10	Redis Persistence Failure - MISCONF Disk Write Errors	Detects Redis MISCONF errors when the server cannot persist data to disk due to RDB/AOF write failures. This critical error prevents Redis from saving snapshots and may lead to data loss on restart.	In-Memory Database Problems	redis	Redis Persistence MISCONF RDB AOF Disk
CRE-2025-0180 Critical Impact: 10/10 Mitigation: 6/10	Redis AOF File Corruption and Recovery Failure	Detects Redis Append-Only File (AOF) corruption that prevents Redis from starting or causes data loss. AOF corruption typically occurs due to unexpected shutdowns, disk errors, or incomplete writes during crashes.	In-Memory Database Problems	redis	Redis AOF Corruption Persistence Recovery
CRE-2025-0200 Critical Impact: 10/10 Mitigation: 7/10	Redis Comprehensive Troubleshooting - Multiple Common Issues Detection	Comprehensive detection rule for multiple common Redis troubleshooting scenarios including: 1. Out-of-Memory (OOM) errors when maxmemory limit exceeded 2. Connection timeouts and connectivity issues 3. Authentication failures and permission denials 4. Invalid commands and argument errors 5. Background save (BGSAVE) conflicts and persistence issues 6. Slow query performance problems 7. Read-only replica write attempts 8. Disk persistence failures (MISCONF errors) 9. Client connection limits exceeded 10.
