Attackers can provide an MPEG file whose stream table bytes all set the high bit, which crashes applications opening it through SMPEG_new, SMPEG_new_rwops, or SMPEG_new_data.","categories":["Unclassified"],"product":"smpeg","vendor":"icculus","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112009","source_modified_at":"2026-10-18T12:23:31.861Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"smpeg","vendor":"icculus","versions":[{"version":"0","lessThanOrEqual":"2.0.0","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.0013,"percentile":0.02358,"score_date":"2026-10-23"},"published_at":"2026-10-18T11:38:31.991Z","modified_at":"2026-10-18T12:23:31.861Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-112009","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-18T12:23:31.861Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-112009","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://hackmd.io/@haindpwn/smpeg-system-header-stream-table-oob-read","tags":["technical-description","exploit"]},{"source":"CVE List","url":"https://github.com/icculus/smpeg/blob/d188dc111f4817288718705e4a84e248803ccfdc/MPEGsystem.cpp#L803-L823","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/icculus/smpeg","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/smpeg-through-2.0.0-heap-out-of-bounds-read-via-mpegsystem-fillbuffer","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-18T12:17:03.445754Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-18T12:23:31.861Z","content_hash":"fa501298b88c215eb6d5f4fd6bd6511ac492a62795adfd06e5630fcd6aeb3e5b"}}
