CVE-2026-78684

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...

Allocation of Resources Without Limits or Throttling

Overview vllm is an A high-throughput and memory-efficient inference and serving engine for LLMs Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the VideoMediaIO.mergekwargs and DeepStream video decoding paths in...

CVE-2026-78684 vLLM before 0.27.0 Denial of Service via DeepStream Backend

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, causin...

CVE-2026-78684

vLLM versions prior to 0.27.0 are susceptible to a denial-of-service condition through improper handling of the DeepStream backend. The root cause is a failure to classify DeepStream as a GPU backend combined with missing pixel-limit enforcement in the decode path. An unauthenticated attacker can...
