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-2026-72477 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-2026-72477/ (Markdown: https://insights.sbomify.com/CVE-2026-72477/index.md)","id":"CVE-2026-72477","markdown":"https://insights.sbomify.com/CVE-2026-72477/index.md","name":"CVE-2026-72477","record":{"aliases":["BELL-CVE-2026-72477","DEBIAN-CVE-2026-72477","GHSA-9679-5mjr-46x9","UBUNTU-CVE-2026-72477"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A flaw in the Linux kernel NTFS3 driver causes a kernel warning and potential instability when rename operations fail, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfs/ntfs3: call _ntfs_bad_inode() when failing to rename\n\nIt is safe to call _ntfs_bad_inode on live inodes since:\n  commit 519b078998ce (\"fs/ntfs3: Exclude call make_bad_inode for live nodes.\")\n\nThe WARN_ON was added when it wasn't safe by:\n  commit d99208b91933 (\"fs/ntfs3: cancle set bad inode after removing name fails\")\n\nReplace the WARN_ON with a call to _ntfs_bad_inode() to prevent further\noperations on the inconsistent inode.","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":"fs/ntfs3: call _ntfs_bad_inode() when failing to rename","id":"CVE-2026-72477","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"fs/ntfs3: add bounds check to run_get_highest_vcn()","id":"CVE-2026-72478"},"packages":[],"prev":{"headline":"dmaengine: Fix possible use after free","id":"CVE-2026-72476"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A flaw in the Linux kernel NTFS3 driver causes a kernel warning and potential instability when rename operations fail, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2026-72477/"}
