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.","published":"2026-09-21T22:04:13.172Z","modified":"2026-09-21T22:04:13.172Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/vllm-project/vllm/pull/51504","label":"vllm-project/vllm#51504"},"references":[{"type":"FIX","url":"https://github.com/vllm-project/vllm/pull/51504"},{"type":"WEB","url":"https://github.com/vllm-project/vllm/blob/v0.29.0/vllm/v1/kv_offload/tiering/p2p/control/zmq.py#L240-L260"},{"type":"WEB","url":"https://github.com/vllm-project/vllm/blob/v0.29.0/vllm/v1/kv_offload/tiering/p2p/manager.py#L667-L677"},{"type":"WEB","url":"https://github.com/vllm-project/vllm"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/vllm-through-0.29.0-denial-of-service-via-unbounded-p2p-kv-offloading-sessions"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-21T22:04:13.172Z"}}
