Summary
vLLM from 0.7.3 before 0.31.0 does not limit the multimodal processor parameters that remote clients set per request through mm_processor_kwargs. This is uncontrolled resource consumption (CWE-400). A remote attacker without privileges can set large image size, patch, crop or frame count values in processors such as Isaac and InternVL, exhausting memory and terminating the shared server.

Description from the CNA
vLLM from 0.7.3 before 0.31.0 contains an uncontrolled resource consumption vulnerability that allows remote clients to control multimodal processor parameters by supplying per-request mm_processor_kwargs. Attackers can set large image size, patch count, crop count, or frame count values in Isaac, InternVL, H2OVL, and other processors to exhaust memory and terminate the shared server.
