Name of the Vulnerable Software and Affected Versions
vLLM versions prior to 0.29.1
Description
A denial of service issue exists in P2P KV offloading when the OffloadingConnector is configured with TieringOffloadingSpec and a peer-to-peer secondary tier. An attacker can provide arbitrary remote host and port values via the
kv transfer params parameter to create unreachable peer sessions. These sessions retain ZeroMQ sockets until the context quota is exhausted, leading to an uncaught ZMQError that crashes EngineCore and halts all inference operations.Recommendations
Update vLLM to a version later than 0.29.0.
