Overview
vllm is an A high-throughput and memory-efficient inference and serving engine for LLMs
Affected versions of this package are vulnerable to Improper Handling of Exceptional Conditions in mooncake_connector.py, the Mooncake KV connector's receiver loop fails to report remote KV load failures back to the scheduler. When a remote KV cache transfer returns an error or raises an exception, the failure is only logged and the affected request's block IDs are never marked invalid, leaving the scheduler unaware that the transfer did not complete. This causes the scheduler to stall waiting for results that will never arrive, resulting in a crash or hang that denies service to all pending requests.
