The bundled utility allocates exactly ini_length bytes, while strip_ini_cache() unconditionally writes a NUL terminator at ini_source[ini_length], requiring an additional writable byte. Applications using the bundled allocation pattern can trigger deterministic heap memory corruption when processing any non-empty INI input, resulting in denial of service.","categories":["Unclassified"],"product":"n/a","vendor":"n/a","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-88370","source_modified_at":"2026-09-25T15:32:04.506Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"n/a","vendor":"n/a","versions":[{"version":"n/a","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00293,"percentile":0.20775,"score_date":"2026-10-23"},"published_at":"2026-09-24T00:00:00.000Z","modified_at":"2026-09-25T15:32:04.506Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-88370","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T15:32:04.506Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-88370","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/madmurphy/libconfini/issues/20","tags":["exploit"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"partial","assessed_at":"2026-09-25T15:31:19.915848Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T15:32:04.506Z","content_hash":"778ec0850d676603a350527996b6cc8059dfc0419956c732e9b771b21e54b32a"}}
