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-2026-111140 exists.\n\nAffected product: libyal libregf. 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-2026-111140/ (Markdown: https://insights.sbomify.com/CVE-2026-111140/index.md)","id":"CVE-2026-111140","markdown":"https://insights.sbomify.com/CVE-2026-111140/index.md","name":"CVE-2026-111140","record":{"aliases":["DEBIAN-CVE-2026-111140","GHSA-4g68-6f29-pjf8","UBUNTU-CVE-2026-111140"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Registry file parsing library","requires_auth":"none","summary":"Attackers can leak heap memory or crash parsers by supplying a crafted REGF hive file to the libregf library.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"libregf through 20260526 contains a heap out-of-bounds read in libregf_value_item_read_value_data() because it bounds value data size without subtracting the 4-byte old-format cell offset.
