| Doc Text: |
A flaw was found in vLLM. An unauthenticated attacker can exploit an input validation vulnerability by submitting negative token IDs to the /v1/embeddings and /pooling endpoints. This action triggers a CUDA device-side assertion, which poisons the GPU context and causes the engine to crash. Consequently, all subsequent requests will fail until the process is restarted, leading to a Denial of Service (DoS).
