It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-19024 exists.\n\nAffected product: The HDF Group HDF5. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-19024/ (Markdown: https://insights.sbomify.com/CVE-2026-19024/index.md)","id":"CVE-2026-19024","markdown":"https://insights.sbomify.com/CVE-2026-19024/index.md","name":"CVE-2026-19024","record":{"aliases":["AZL-94505","DEBIAN-CVE-2026-19024","ECHO-15c1-bb78-dbe9","GHSA-c7cf-qx8c-5ph7","RHSA-2026:79131","UBUNTU-CVE-2026-19024"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"HDF5 data library","requires_auth":"none","summary":"Attackers can cause denial of service in HDF5 by providing a malformed fill value message with a negative size field.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HDFG","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","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:H","version":"4.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"NULL pointer dereference in H5Pget_fill_value in HDF5 before 2.3.0 allows attackers to cause a denial of service via a dataset whose version 1 or 2 fill value message has the \"defined\" flag set together with a negative size field, which is not normalized to the library's \"undefined\" sentinel and reaches H5T_path_find with a NULL datatype.","ecosystems":["Red Hat:hummingbird:1"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"HDF5 H5Pget_fill_value NULL Pointer Dereference via Malformed Fill Value Message","id":"CVE-2026-19024","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":10,"n_references":1,"next":{"headline":"HDF5 divide-by-zero (SIGFPE) via mismatched chunk-layout dimensionality and dataspace rank on dataset open","id":"CVE-2026-19025"},"packages":[{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.2.0-0.1.3.hum1"],"introduced":["0"],"last_affected":[],"package":"hdf5","purl":"pkg:rpm/redhat/hdf5","source":"RHSA-2026:79131"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.2.0-0.1.3.hum1"],"introduced":["0"],"last_affected":[],"package":"hdf5-devel","purl":"pkg:rpm/redhat/hdf5-devel","source":"RHSA-2026:79131"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.2.0-0.1.3.hum1"],"introduced":["0"],"last_affected":[],"package":"hdf5-mpich","purl":"pkg:rpm/redhat/hdf5-mpich","source":"RHSA-2026:79131"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.2.0-0.1.3.hum1"],"introduced":["0"],"last_affected":[],"package":"hdf5-mpich-devel","purl":"pkg:rpm/redhat/hdf5-mpich-devel","source":"RHSA-2026:79131"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.2.0-0.1.3.hum1"],"introduced":["0"],"last_affected":[],"package":"hdf5-mpich-static","purl":"pkg:rpm/redhat/hdf5-mpich-static","source":"RHSA-2026:79131"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.2.0-0.1.3.hum1"],"introduced":["0"],"last_affected":[],"package":"hdf5-openmpi","purl":"pkg:rpm/redhat/hdf5-openmpi","source":"RHSA-2026:79131"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.2.0-0.1.3.hum1"],"introduced":["0"],"last_affected":[],"package":"hdf5-openmpi-devel","purl":"pkg:rpm/redhat/hdf5-openmpi-devel","source":"RHSA-2026:79131"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.2.0-0.1.3.hum1"],"introduced":["0"],"last_affected":[],"package":"hdf5-openmpi-static","purl":"pkg:rpm/redhat/hdf5-openmpi-static","source":"RHSA-2026:79131"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.2.0-0.1.3.hum1"],"introduced":["0"],"last_affected":[],"package":"hdf5-static","purl":"pkg:rpm/redhat/hdf5-static","source":"RHSA-2026:79131"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:2.2.0-0.1.3.hum1"],"introduced":["0"],"last_affected":[],"package":"java-hdf5","purl":"pkg:rpm/redhat/java-hdf5","source":"RHSA-2026:79131"}],"prev":{"headline":"HDF5 h5dump Untrusted Pointer Dereference in Binary Output of Variable-Length String Datasets","id":"CVE-2026-19023"},"products":["HDF5"],"published":"2026-08-05","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-06","vendors":["The HDF Group"]},"summary":"Attackers can cause denial of service in HDF5 by providing a malformed fill value message with a negative size field.","url":"https://insights.sbomify.com/CVE-2026-19024/"}
