CyberRota Analysis

AI-Generated

vLLM versions prior to 0.27.0 are vulnerable due to improper classification of DeepStream as a GPU backend, which leads to a lack of pixel-limit enforcement in the decoding process. This flaw allows unauthenticated attackers to exploit the system by initializing the GPU decode pool and submitting video that can overwhelm resources, potentially causing partial denial of service for legitimate requests. Organizations using vLLM should prioritize updating to the latest version to mitigate this risk.

Original NVD Description

vLLM before 0.27.0 fails to properly classify DeepStream as a GPU backend and omits pixel-limit enforcement in its decode path. Unauthenticated attackers can activate DeepStream at request time to initialize the process-wide GPU decode pool and submit video that bypasses resource controls, causing partial denial of service for concurrent requests.
