{"schema":"threatline.record/2","record":{"id":"CVE-2026-19029","aliases":[],"summary":"HDF5 scale-offset filter heap buffer over-read via crafted chunk","details":"A heap-based buffer over-read in H5Z__filter_scaleoffset() in src/H5Zscaleoffset.c in HDF5 through 2.2.0 lets an attacker cause a denial of service (application crash) with a crafted HDF5 file. When the stored minimum bits equal the full precision of the datatype, the decoder copies d_nelmts * size bytes from the compressed chunk without checking that the chunk holds that many bytes. Both values come from attacker-controlled scale-offset filter parameters in the dataset's filter pipeline message.","categories":["Unclassified"],"product":"HDF5","vendor":"The HDF Group","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-19029","source_modified_at":"2026-10-07T16:05:28.833Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"HDF5","vendor":"The HDF Group","versions":[{"status":"affected","version":"< 2.2.0"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00118,"percentile":0.01616,"score_date":"2026-10-23"},"published_at":"2026-10-06T20:01:36.340Z","modified_at":"2026-10-07T16:05:28.833Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-19029","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-07T16:05:28.833Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-19029","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/HDFGroup/hdf5/pull/6718"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-07T16:04:23.864171Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-07T16:05:28.833Z","content_hash":"94aaa2da0ab27d274e34e63e8e1175ac79954133003d6bc1908c93499245bd69"}}
