CVE-2026-116175: vLLM audio decompression bomb in chat completions

CVE-2026-116175 · Severity: medium · CVSS 6.5 · Published 2026-10-25

vLLM is a large language model inference engine that supports multimodal inputs including audio. Authenticated attackers can submit chat requests containing small compressed audio files that expand to enormous decoded audio data, exhausting server memory and degrading service availability. An attacker needs only valid credentials and can exploit the vulnerability either by uploading audio directly or referencing an audio file via URL.

Technical details

A decompression bomb vulnerability in the AudioMediaIO multimodal audio processing path fails to apply the max_duration_s decoded-duration limit when loading audio from input_audio or audio_url parameters in /v1/chat/completions requests. The load_audio() function supports duration limiting, but the chat path invokes it without passing the limit, allowing attackers to provide small compressed audio that expands to exhaustive decoded PCM samples. This is a sibling vulnerability to a prior audio decompression-bomb fix that addressed the speech-to-text path but left the chat multimodal path unpatched.

Affected products
