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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-129"],"references":["https://github.com/vllm-project/vllm/security/advisories/GHSA-25q3-v2hm-8vpf","https://www.vulncheck.com/advisories/vllm-before-0.28.0-denial-of-service-via-negative-token-id","https://github.com/vllm-project/vllm/security/advisories/GHSA-25q3-v2hm-8vpf"],"products":["vllm:vllm"],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-93592","score":0.00544,"percentile":0.45707,"date":"2026-10-31"},"kev":null,"osv":[{"id":"PYSEC-2026-3997","url":"https://osv.dev/vulnerability/PYSEC-2026-3997","summary":"","modified":"2026-09-29T09:00:03.002511196Z","packages":[{"ecosystem":"PyPI","name":"vllm","purl":"pkg:pypi/vllm","ranges":["<0.28.0"],"fixed":["0.28.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
