Attackers can supply a crafted .sf2 file with out-of-range pgen/igen operator values to write chosen 16-bit values near the stack Layer object, causing crashes and stack memory corruption.","categories":["Unclassified"],"product":"libtimidity","vendor":"sezero","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-111154","source_modified_at":"2026-10-15T18:57:42.295Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"libtimidity","vendor":"sezero","versions":[{"version":"0.2.8","lessThanOrEqual":"0.2.8","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.0013,"percentile":0.02361,"score_date":"2026-10-23"},"published_at":"2026-10-15T18:57:42.295Z","modified_at":"2026-10-15T18:57:42.295Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-111154","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T18:57:42.295Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-111154","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/@haind-pwn/libtimidity-soundfont-generator-oper-oob-write","tags":["technical-description","exploit"]},{"source":"CVE List","url":"https://github.com/sezero/libtimidity/blob/a52adf6aee2635e2a16797213a089c2180e67757/src/sndfont.c#L468-L480","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/sezero/libtimidity","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/libtimidity-through-0.2.8-stack-out-of-bounds-write-via-parse-gen-in-soundfont-loader","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T18:57:42.295Z","content_hash":"0322b19d053ca60d5f1cffb9ac0708bb02a17a2abf632d761c4fc90921e8d585"}}
