CVE-2026-116175

vLLM 0.19.0 before 0.24.0 Audio Decompression Bomb DoS via Chat Completions

State: Published
Severity: 7.1 High
Published: Oct 25, 2026
Updated: Oct 26, 2026
Reserved: Oct 25, 2026

Description

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.
