| CRE-2025-0032 Low Impact: 2/10 Mitigation: 4/10 | Loki generates excessive logs when memcached service port name is incorrect | Loki instances using memcached for caching may emit excessive warning or error logs when the configured`memcached_client` service port name does not match the actual Kubernetes service port. This does not cause a crash or failure, but it results in noisy logs and ineffective caching behavior. | Observability Problems | loki | LokiMemcachedConfigurationServiceCacheKnown IssueKubernetesPublic |
| CRE-2025-0038 Low Impact: 5/10 Mitigation: 3/10 | Loki fails to cache entries due to Memcached out-of-memory error | Grafana Loki may emit errors when attempting to write to a Memcached backend that has run out of available memory. This results in dropped index or query cache entries, which can degrade query performance but does not interrupt ingestion. | Observability Problems | loki | LokiMemcachedCacheMemoryInfrastructureKnown IssuePublic |
