Kerentanan Memory Allocation with Excessive Size Value pada vllm. Skor CVSS 3.1 7.5 (High) menurut vulncheck.com.

Deskripsi (NVD)

vLLM through 0.29.0 fails to validate the tp_size parameter in kv_transfer_params on OpenAI-compatible completion endpoints, allowing attackers to allocate unbounded memory. Attackers can supply arbitrary tp_size values in prefill/decode disaggregated deployments to exhaust memory and trigger kernel OOM-kill of the decode worker process.
