Attackers can supply a crafted .tta file declaring zero channels so decorrelation accesses cache[-1] with stream-derived values, corrupting stack memory in decoding applications.","categories":["Unclassified"],"product":"libtta","vendor":"True Audio","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112012","source_modified_at":"2026-10-19T16:38:35.225Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"libtta","vendor":"True Audio","versions":[{"version":"0","lessThanOrEqual":"2.3","status":"affected","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":4.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00125,"percentile":0.02041,"score_date":"2026-10-23"},"published_at":"2026-10-18T11:38:34.029Z","modified_at":"2026-10-19T16:38:35.225Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-112012","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T16:38:35.225Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-112012","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/libtta-seek-table-count-overflow-oob-write","tags":["technical-description","exploit"]},{"source":"CVE List","url":"https://github.com/gchudov/libtta/blob/af8dc48ce859e98842ab1a3eec98416d22a5199e/libtta.c#L618","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/gchudov/libtta/blob/af8dc48ce859e98842ab1a3eec98416d22a5199e/libtta.c#L715-L730","tags":["technical-description"]},{"source":"CVE List","url":"https://sourceforge.net/projects/tta/","tags":["product"]},{"source":"CVE List","url":"https://github.com/gchudov/libtta","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/libtta-through-2.3-stack-out-of-bounds-write-via-zero-channel-count","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":"2026-10-19T15:57:51.623269Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-19T16:38:35.225Z","content_hash":"852844cf9e97b4aaf8dd6d37febba1dd38056e1ff6aaf93b08a1444f8a2f6a34"}}
