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.","published":"2026-09-18T13:20:05.365Z","modified":"2026-09-18T13:20:05.365Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-25q3-v2hm-8vpf"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/vllm-before-0.28.0-denial-of-service-via-negative-token-id"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-18T13:20:05.365Z"}}
