{"id":"CVE-2026-112009","summary":"smpeg through 2.0.0 Heap Out-of-Bounds Read via MPEGsystem::FillBuffer","details":"smpeg through 2.0.0 contains a heap out-of-bounds read vulnerability in MPEGsystem::FillBuffer() that allows attackers to read past the 16384-byte buffer by supplying a crafted system header stream table. 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.","modified":"2026-10-19T02:45:45.597369166Z","published":"2026-10-18T11:38:31.991Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112009.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112009.json"},{"type":"PACKAGE","url":"https://github.com/icculus/smpeg"},{"type":"ARTICLE","url":"https://github.com/icculus/smpeg/blob/d188dc111f4817288718705e4a84e248803ccfdc/MPEGsystem.cpp#L803-L823"},{"type":"EVIDENCE","url":"https://hackmd.io/@haindpwn/smpeg-system-header-stream-table-oob-read"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112009"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/smpeg-through-2.0.0-heap-out-of-bounds-read-via-mpegsystem-fillbuffer"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/icculus/smpeg","events":[{"introduced":"0"},{"last_affected":"62aafbc4ee032c1e9ef02ac8bf98b908c5af62ea"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"2.0.0"}],"source":"AFFECTED_FIELD"}}],"versions":["release_2_0_0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-112009.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
