{"id":"CVE-2026-111163","summary":"WildMIDI through 0.5.0 Heap Out-of-Bounds Read via _WM_ParseNewHmi","details":"WildMIDI through 0.5.0 contains a heap out-of-bounds read vulnerability in _WM_ParseNewHmi() in src/f_hmi.c that reads past buffers when handling 0xfe sub-events. Attackers can supply a crafted HMI file placing a 0xfe 0x10 sub-event near the buffer end to read up to four bytes past the allocation, crashing the decoding application.","modified":"2026-10-17T02:48:20.283382855Z","published":"2026-10-15T18:57:50.508Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111163.json"},"references":[{"type":"WEB","url":"https://github.com"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111163.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111163"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/wildmidi-through-0.5.0-heap-out-of-bounds-read-via-wm-parsenewhmi"},{"type":"PACKAGE","url":"https://github.com/Mindwerks/wildmidi"},{"type":"ARTICLE","url":"https://github.com/Mindwerks/wildmidi/blob/340472ed4633d139d30c660b90eca03c1320e593/src/f_hmi.c#L268-L290"},{"type":"ARTICLE","url":"https://hackmd.io/@haind-pwn/wildmidi-hmp-chunk-length-underflow-oob-read"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mindwerks/wildmidi","events":[{"introduced":"0"},{"fixed":"340472ed4633d139d30c660b90eca03c1320e593"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"0.5.0"},{"fixed":"0.5.0"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["wildmidi-0.4.6","wildmidi-0.4.5","wildmidi-0.4.4","wildmidi-0.4.3","wildmidi-0.4.2","wildmidi-0.4.1","wildmidi-0.4.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111163.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"}]}
