CVE-2026-90554
Description
A flaw was found in vLLM. This vulnerability allows a remote attacker to cause a denial of service by providing a specially crafted, highly compressed video as multimodal input when the NanoNemotronVL model is configured to use audio from video. The lack of proper size or duration limits during audio extraction from the video input can force the server to allocate excessive memory, leading to system instability and preventing legitimate users from accessing the service.
Statement
This vulnerability has a Moderate impact on Red Hat products. When vLLM is configured to extract audio from video input for NanoNemotronVL models with use_audio_in_video=True, a remote attacker can provide a small, highly compressed video to trigger excessive memory allocation. This can lead to a denial of service for the vLLM server, impacting the availability of AI inference services.
Mitigation
To mitigate this issue, disable the `use_audio_in_video` feature if it is not required for your deployment. This prevents the vulnerable audio extraction code path from being exercised. If disabling this feature is not feasible, 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.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
