An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-72318 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-72318/ (Markdown: https://insights.sbomify.com/CVE-2026-72318/index.md)","id":"CVE-2026-72318","markdown":"https://insights.sbomify.com/CVE-2026-72318/index.md","name":"CVE-2026-72318","record":{"aliases":["BELL-CVE-2026-72318","DEBIAN-CVE-2026-72318","GHSA-4cv4-fc78-7hch","UBUNTU-CVE-2026-72318"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel CIFS","requires_auth":"none","summary":"A malformed DFS referral in the Linux kernel CIFS module can cause out-of-bounds reads, potentially leading to denial of service or information disclosure.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncifs: validate DFS referral string offsets\n\nparse_dfs_referrals() validates that the response header and referral\narray fit in the received buffer, but each referral also contains string\noffsets supplied by the server.\n\nThose offsets are used to compute the DfsPath and NetworkAddress string\npointers without checking whether they still point inside the response\nbuffer.
