A specially crafted EXR file containing an unknown-type attribute with dataSize set to zero causes the parser to create an opaque attribute with a NULL packed_data pointer. The OpaqueAttribute constructor passes the NULL pointer to memcpy() without validating the zero-size condition, resulting in undefined behavior and process termination, leading to 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-2026-88384","source_modified_at":"2026-09-24T18:18:33.846Z","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":0.00193,"percentile":0.08485,"score_date":"2026-10-23"},"published_at":"2026-09-24T00:00:00.000Z","modified_at":"2026-09-24T18:18:33.846Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-88384","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-24T18:18:33.846Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-88384","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/AcademySoftwareFoundation/openexr/issues/2612","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/AcademySoftwareFoundation/openexr/pull/2615"},{"source":"CVE List","url":"https://github.com/AcademySoftwareFoundation/openexr/pull/2615/changes/70ddecfe82d2566f3776b8ed923939afd47baca2"}],"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":"2026-09-24T18:17:56.727213Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-24T18:18:33.846Z","content_hash":"a749971e858c9701bd8d508fa62a1bed47d4279c4d96e846fb1b267c7bbc7b3e"}}
