How to fix?

Upgrade Minimos:latest vllm-cu130-wheels to version 0.29.0-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream vllm-cu130-wheels package and not the vllm-cu130-wheels package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

vLLM before 0.29.0 validates allowed_token_ids against tokenizer length instead of model output logits width in SamplingParams._validate_allowed_token_ids(). Attackers can supply token IDs above the output vocabulary that pass validation, causing LogitBiasState to corrupt GPU logits state and allow concurrent requests to sample tokens outside their allowlists.
