An attacker can exploit it over the internet without logging in, 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-2026-110712 exists.\n\nAffected product: sahlberg libsmb2. 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-2026-110712/ (Markdown: https://insights.sbomify.com/CVE-2026-110712/index.md)","id":"CVE-2026-110712","markdown":"https://insights.sbomify.com/CVE-2026-110712/index.md","name":"CVE-2026-110712","record":{"aliases":["DEBIAN-CVE-2026-110712","GHSA-r4h5-4wv2-c8cj","UBUNTU-CVE-2026-110712"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SMB client library","requires_auth":"none","summary":"A heap out-of-bounds read in libsmb2 allows malicious SMB servers to crash clients via crafted file information replies.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"libsmb2 through 6.2 contains a heap out-of-bounds read vulnerability in smb2_decode_file_all_info that allows malicious SMB servers to crash clients by sending an unchecked FileNameLength.
