{"id":"CVE-2026-90554","summary":"vLLM before 0.28.0 Denial of Service via audio extraction","details":"vLLM versions \u003e=0.10.2 and \u003c0.28.0 do not apply any audio decode-size or duration limit when extracting audio from video input for NanoNemotronVL models. In nano_nemotron_vl.py, _extract_audio_from_videos calls load_audio_pyav(BytesIO(video_bytes)) without the max_duration_s or max_decode_bytes parameters, so neither VLLM_MAX_AUDIO_DECODE_DURATION_S nor VLLM_MAX_AUDIO_DECODE_BYTES is enforced (unlike the direct audio upload path in AudioMediaIO). When a NanoNemotronVL model is served with use_audio_in_video=True, an attacker who supplies a small, highly compressed video as multimodal input can force the server to allocate gigabytes of memory during audio decoding, resulting in a denial of service. Fixed in vLLM 0.28.0.","aliases":["GHSA-936p-m5pv-vvjf"],"modified":"2026-09-13T03:47:24.997567170Z","published":"2026-09-12T12:08:57.508Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90554.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-400"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90554.json"},{"type":"ADVISORY","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-936p-m5pv-vvjf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90554"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/vllm-before-0.28.0-denial-of-service-via-audio-extraction"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/vllm-project/vllm","events":[{"introduced":"01efc7ef781391e744ed08c3292817a773d654e6"},{"fixed":"2cf0a6915ce544dc493a0990f2ea38d81601128a"}],"database_specific":{"extracted_events":[{"introduced":"0.10.2"},{"fixed":"0.28.0"}],"source":"AFFECTED_FIELD"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90554.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
