From 2.2.7 until 2.2.11, ServiceSentinel.worker in service\/singleton\/servicesentinel.go checked an owned service under servicesLock and later dereferenced pointer-valued serviceStatusToday and serviceCurrentStatusData entries under serviceResponseDataStoreLock without revalidating that ServiceSentinel.Delete had not removed them. A RoleMember could concurrently report TCP or ICMP results through the member&#8217;s own agent and delete the same owned service, causing a nil pointer dereference. Because the gRPC server had no recovery interceptor, the worker panic terminated the whole dashboard process and disrupted every tenant&#8217;s web interface, REST API, and agent connections. The issue affects availability only and does not disclose or modify data.
