CVE-2026-93592

HIGHCVSS 7.5/10

Last modified

CVE-2026-93592 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. vLLM versions before 0.28.0 fail to validate the lower bound of token IDs in the /v1/embeddings and /pooling endpoints, allowing unauthenticated attackers to crash the engine by submitting negative token IDs. A single request with a negative token ID triggers a CUDA device-side assertion that poisons the GPU context, causing all subsequent requests to fail until the process restarts..
