CVE-2026-55646

Описание

vLLM is an inference and serving engine for large language models. From 0.22.0 to 0.23.0, the /v1/audio/transcriptions and /v1/audio/translations routes call request.file.read() to fully materialize an uploaded audio file into memory before vLLM checks the documented VLLM_MAX_AUDIO_CLIP_FILESIZE_MB compressed upload size limit (default 25 MB) later in the speech-to-text preprocessing step, so an API caller who can reach those routes can submit an oversized multipart upload and cause vLLM to allocate memory proportional to the uploaded file size before the request is rejected as too large, creating memory pressure or terminating the process depending on deployment resource limits. This issue is fixed in version 0.24.0.

A flaw was found in vLLM, an inference and serving engine for large language models. A remote attacker, by submitting an oversized audio file to the /v1/audio/transcriptions or /v1/audio/translations routes, can cause the system to allocate excessive memory. This occurs before the configured file size limit is checked, leading to memory pressure or process termination, resulting in a Denial of Service (DoS).

Отчет

This Moderate denial of service flaw in vLLM, which could lead to excessive memory allocation when processing oversized audio files, does not affect Red Hat products. The vulnerable code is not present in Red Hat's supported offerings.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
