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.","state":0,"publishedAt":"2026-10-06T20:01:36.34+00:00","modifiedAt":"2026-10-07T16:05:28.833+00:00","affected":[{"ecosystem":"Vendor product","name":"HDF5","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"The HDF Group\",\n                    \"product\": \"HDF5\",\n                    \"modules\": [\n                        \"H5Z__filter_scaleoffset\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"< 2.2.0\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":6.8,"severity":"MEDIUM"}],"references":["https://github.com/HDFGroup/hdf5/pull/6718"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-19029","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-19029","identifiers":["CVE-2026-19029"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
