When min_tokens is greater than 0, an out-of-range id reaches a CUDA index_put_ operation and triggers a device-side assertion. An authenticated API user can send one malformed request that returns 500 Internal Server Error and leaves EngineCore in a fatal state, so later requests fail until the service restarts (denial of service).","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-100654","publishedAt":"2026-09-26T14:16:48.100Z","cveId":"CVE-2026-100654","cweIds":["CWE-129"],"cvssScore":"6.5","cvssSeverity":"medium","severity":"medium","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["vLLM"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"vLLM denial of service via stop_token_ids in completion endpoints","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","attackVector":"network","attackComplexity":"low","privilegesRequired":"low","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00314,"epssCheckedAt":"2026-11-11T18:11:47.759Z","kevDateAdded":null,"advisoryAliases":["GHSA-9fp6-6v59-w2jx"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-08T00:10:17.686Z","patchAvailable":null,"disclosureDate":"2026-09-26T14:16:48.100Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["availability"],"aiComponentTargeted":"inference","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null,"fixes":[]}}
