Doc Text:
A flaw was found in vLLM. This vulnerability allows a remote authenticated attacker to cause a Denial of Service (DoS) by exhausting system memory. The multimodal chat processing component fails to enforce duration limits when decompressing audio inputs. By submitting a chat completion request containing a small, highly compressed audio file or URL, an attacker can trigger massive data expansion that crashes or severely degrades the service.

Description OSIDB Bzimport 2026-10-25 13:33:21 UTC 
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.
