A specially crafted RAW, TIFF, or DNG file can supply an attacker-controlled NewSubfileType value outside the range of a signed int. The parser converts this value and narrows it to int without performing range validation. This out-of-range conversion triggers undefined behavior, resulting in process termination and 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-2026-88387","source_modified_at":"2026-09-29T02:39:24.148Z","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":5.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00118,"percentile":0.01628,"score_date":"2026-10-23"},"published_at":"2026-09-24T00:00:00.000Z","modified_at":"2026-09-29T02:39:24.148Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-88387","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-29T02:39:24.148Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-88387","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/LibRaw/LibRaw/issues/844","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/LibRaw/LibRaw/pull/853"},{"source":"CVE List","url":"https://github.com/LibRaw/LibRaw/commit/b41cbbd61951783e0440590dae55411a16185bdf"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-29T02:38:06.086578Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-29T02:39:24.148Z","content_hash":"1e287fd66d8dd88f777941f89d765baa0744086a79f5b80ba5f171f16416bae7"}}
