{"schemaVersion":3,"id":"GHSA-78FP-CF4H-G36P","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Duplicate Advisory: vLLM introduced enhanced protection for CVE-2025-62164\n\n### Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-mcmc-2m55-j8jj. This link is maintained to preserve external references.\n\n### Original Description\n\nvLLM versions >= 0.10.2 and < 0.13.0 are missing sparse tensor validation in multimodal embeddings processing. Because PyTorch disables sparse tensor invariant checks by default, an attacker can submit crafted embedding requests with malformed (negative or out-of-bounds) tensor indices, when the prompt-embeds feature is enabled, to trigger crashes or resource exhaustion (denial of service), with potential for out-of-bounds/write-what-where memory corruption. This continues CVE-2025-62164, whose prior fix only disabled the feature by default rather than addressing the root cause.","dates":{"published":"2026-06-20T21:31:21.000Z","modified":"2026-09-11T19:30:05.032Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.7,"severity":"high","version":"4.0","versionLabel":"v4.0","source":"OSV · Pypi","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","computed":true,"selection":"version-preference"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"OSV · Pypi","score":8.7,"severity":"high","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","exploitability":null,"impact":null,"computed":true},{"version":"3.1","versionLabel":"v3.1","source":"OSV · Pypi","score":8.8,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":7.2,"impact":9.8,"computed":true}]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"PyPI","product":"vllm","name":"vllm","label":"vllm","ecosystem":"PyPI","cpePart":null,"purl":"pkg:pypi/vllm","purlType":"pypi","versions":[{"text":"≥ 0.10.2, < 0.13.0","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 0.10.2, < 0.13.0","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-mcmc-2m55-j8jj","label":"github.com/vllm-project/vllm/security/advisories/GHSA-mcmc-2m55-j8jj","hostname":"github.com","tags":["WEB"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-56340","label":"nvd.nist.gov/vuln/detail/CVE-2026-56340","hostname":"nvd.nist.gov","tags":["Advisory"]},{"url":"https://access.redhat.com/security/cve/CVE-2026-56340","label":"access.redhat.com/security/cve/CVE-2026-56340","hostname":"access.redhat.com","tags":["WEB"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2491060","label":"bugzilla.redhat.com/show_bug.cgi?id=2491060","hostname":"bugzilla.redhat.com","tags":["WEB"]},{"url":"https://github.com/vllm-project/vllm","label":"github.com/vllm-project/vllm","hostname":"github.com","tags":["PACKAGE"]},{"url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-56340.json","label":"security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-56340.json","hostname":"security.access.redhat.com","tags":["WEB"]},{"url":"https://www.vulncheck.com/advisories/vllm-denial-of-service-via-unvalidated-multimodal-embeddings","label":"www.vulncheck.com/advisories/vllm-denial-of-service-via-unvalidated-multimodal-embeddings","hostname":"www.vulncheck.com","tags":["WEB"]}],"lineage":{"upstream":[],"downstream":["CVE-2026-56340"],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-06-20T21:31:21.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-09-11T19:30:05.032Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":35,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-21T18:14:42.480Z","stale":false,"partial":false}}
