## Overview

vLLM from 0.19.0 before 0.24.0 contains a decompression bomb vulnerability because the AudioMediaIO multimodal path calls load_audio without the max_duration_s decoded-duration limit. Authenticated attackers can send small compressed audio via input_audio or audio_url in /v1/chat/completions requests that expands to huge decoded PCM, exhausting server memory.

## Affected

- `vllm >= 0.19.0 < 0.24.0`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
