Duplicate Advisory: vllm p2p never connected zmq_exhaustion
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-frvg-qw88-hww9. This link is maintained to preserve external references.

Original Description

vLLM through 0.29.0 contains a denial of service vulnerability in P2P KV offloading when OffloadingConnector is configured with TieringOffloadingSpec and a peer-to-peer secondary tier. Attackers can supply arbitrary remote host and port values in kv_transfer_params to create unreachable peer sessions that retain ZeroMQ sockets until the context quota is exhausted, causing an uncaught ZMQError that crashes EngineCore and stops all inference.
