NVD Description

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

vLLM through 0.29.0 fails to properly validate bad_words token indices against the model's generation output width in SamplingParams.update_from_tokenizer(). Attackers can supply out-of-bounds token indices that corrupt logits memory of concurrent requests, causing different in-flight HTTP requests to return incorrect tokens.
