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: There is no known exploitation of CVE-2026-17572 in the wild and no public exploit code.\n\nAffected product: Hdfgroup 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-2026-17572/ (Markdown: https://insights.sbomify.com/CVE-2026-17572/index.md)","id":"CVE-2026-17572","markdown":"https://insights.sbomify.com/CVE-2026-17572/index.md","name":"CVE-2026-17572","record":{"aliases":["AZL-94016","DEBIAN-CVE-2026-17572","ECHO-94c1-7eed-d5a9","GHSA-9mx5-fj64-m52r","JLSEC-2026-1384","UBUNTU-CVE-2026-17572"],"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 a denial of service via a crafted HDF5 file triggering a heap buffer overflow in the SOHM list-index deserialization code.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HDFG","cpe":[{"product":"hdf5","vendor":"hdfgroup"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:H/SC:N/SI:L/SA:H/E:U","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Heap-based buffer overflow in the SOHM list-index deserialization code in HDF5 through 2.1.1 on all platforms allows attackers to cause a denial of service (crash) via a crafted HDF5 file whose shared-message list index declares a num_messages count exceeding list_max, triggering out-of-bounds heap reads and writes in H5SM__cache_list_deserialize and H5SM__cache_list_verify_chksum.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"HDF5 SOHM List Index Heap Buffer Overflow","id":"CVE-2026-17572","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"hdfgroup:hdf5","products":["hdfgroup:hdf5"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Double Free in H5D__chunk_copy() in HDF5 via a Crafted Chunk-Index Size Field","id":"CVE-2026-17573"},"packages":[],"prev":{"headline":"Fluent Forms \u003c= 6.2.8 - Reflected Cross-Site Scripting via 'param'","id":"CVE-2026-17571"},"products":["HDF5"],"published":"2026-07-27","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-32608","kev_date_added":null,"published":"2024-10-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-29157","kev_date_added":null,"published":"2024-05-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-29159","kev_date_added":null,"published":"2024-05-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-29164","kev_date_added":null,"published":"2024-05-09"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2024-32611","kev_date_added":null,"published":"2024-05-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-32615","kev_date_added":null,"published":"2024-05-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-32621","kev_date_added":null,"published":"2024-05-09"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-27","vendors":["The HDF Group"]},"summary":"Attackers can cause a denial of service via a crafted HDF5 file triggering a heap buffer overflow in the SOHM list-index deserialization code.","url":"https://insights.sbomify.com/CVE-2026-17572/"}
