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.

CVE-2026-78684 [MEDIUM] CWE-770 vllm: vLLM: Denial of Service via DeepStream backend resource control bypass.
vllm: vLLM: Denial of Service via DeepStream backend resource control bypass.
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.
A flaw was found in vLLM. Unauthenticated attackers can exploit this vulnerability by activating the DeepStream backend during a request. This allows them to initialize the process-wide GPU decode pool and submit video that bypasses resource controls, leading to a partial denial of service for concurrent requests.
