Completion requests containing multiple prompts of varying lengths trigger an assertion failure in NixlBaseConnectorWorker._apply_prefix_caching, because block counts are not properly validated. The resulting crash makes the decode worker unavailable until it is restarted.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-94623","publishedAt":"2026-09-21T22:17:01.123Z","cveId":"CVE-2026-94623","cweIds":["CWE-617"],"cvssScore":"7.5","cvssSeverity":"high","severity":"high","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 through NIXL connector prefix caching","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","attackVector":"network","attackComplexity":"low","privilegesRequired":"none","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00627,"epssCheckedAt":"2026-11-10T00:11:22.945Z","kevDateAdded":null,"advisoryAliases":["GHSA-g3cp-v4cp-9xfq"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-08T06:09:40.011Z","patchAvailable":null,"disclosureDate":"2026-09-21T22:17:01.123Z","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":[]}}
