{"id":"CVE-2026-116730","aliases":[],"title":"Furnace through 0.6.8.3 Out-of-Bounds Read via FamiTracker Module Import","description":"Furnace through 0.6.8.3 contains an out-of-bounds heap read vulnerability in DivEngine::loadFTM() in src/engine/fileOps/ftm.cpp, triggered by an unbounded DPCM note count during FamiTracker module import. Attackers can craft a .ftm, .dnm or 0CC/E-FamiTracker module with a 2A03 instrument note count above 120 to read past the noteMap array and crash Furnace when opened.","severity":"medium","score":6.8,"published":"2026-10-26T21:52:32.251Z","modified":"2026-10-27T14:17:14.912Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://github.com/tildearrow/furnace/issues/2966","https://github.com/tildearrow/furnace","https://github.com/tildearrow/furnace/commit/c120c72391e3229fe258e5759f43427febcb8693","https://github.com/tildearrow/furnace/blob/v0.6.8.3/src/engine/fileOps/ftm.cpp#L981-L1017","https://hackmd.io/@haindpwn/furnace-ftm-import-notemap-and-groove-subsong-oob","https://www.vulncheck.com/advisories/furnace-through-0.6.8.3-out-of-bounds-read-via-famitracker-module-import"],"sources":[{"name":"CVE","id":"CVE-2026-116730","modified":"2026-10-27T14:17:14.912Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-116730"}],"assessments":[{"source":"CNA","vector":"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","score":6.8},{"source":"CNA","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":5.5}]}
