{"id":"CVE-2026-105758","summary":"vLLM: Qwen2-VL / Qwen3-VL video samplers bound on request-controlled max_frames, which the num_frames ceiling does not reach","details":"vLLM is an inference and serving engine for large language models. From 0.24.0 until 0.30.0, the Qwen2VLVideoBackend and Qwen3VLVideoBackend classes accept request-level values for the media_io_kwargs.video.max_frames and media_io_kwargs.video.fps fields without enforcing server-side ceilings. An unauthenticated caller can submit these values to the /tokenize endpoint, causing the sampler to decode every frame selected from attacker-controlled video input, consume disproportionate frontend memory, and potentially terminate the API process before scheduling or admission control. The Rust frontend is not affected because it rejects the media_io_kwargs field. This issue is fixed in version 0.30.0.","aliases":["GHSA-x6mc-67gf-chw4"],"modified":"2026-10-07T02:47:27.515199204Z","published":"2026-10-05T22:54:53.846Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105758.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-770"]},"references":[{"type":"WEB","url":"https://github.com/vllm-project/vllm/releases/tag/v0.30.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105758.json"},{"type":"ADVISORY","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-x6mc-67gf-chw4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105758"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/commit/ea723c81c3ea26425cb69503a5d5e90822a04a45"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/pull/56729"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/vllm-project/vllm","events":[{"introduced":"217c64a976869883fcf0c52a8cf8bc3c954d285b"},{"fixed":"ea723c81c3ea26425cb69503a5d5e90822a04a45"},{"fixed":"9ed533eb4adfe48aef7e569a08daeccd2a773fed"}],"database_specific":{"extracted_events":[{"introduced":"0.24.0"},{"fixed":"0.30.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-105758.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
