It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-40313 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-2025-40313/ (Markdown: https://insights.sbomify.com/CVE-2025-40313/index.md)","id":"CVE-2025-40313","markdown":"https://insights.sbomify.com/CVE-2025-40313/index.md","name":"CVE-2025-40313","record":{"aliases":["BELL-CVE-2025-40313","DEBIAN-CVE-2025-40313","GHSA-2c7r-cgw2-h422","ROOT-OS-DEBIAN-12-CVE-2025-40313","ROOT-OS-DEBIAN-13-CVE-2025-40313","ROOT-OS-UBUNTU-2204-CVE-2025-40313","ROOT-OS-UBUNTU-2404-CVE-2025-40313","UBUNTU-CVE-2025-40313"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A flaw in the Linux kernel ntfs3 driver mishandles $Extend records, potentially causing system instability or crashes when accessing specific NTFS structures.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nntfs3: pretend $Extend records as regular files\n\nSince commit af153bb63a33 (\"vfs: catch invalid modes in may_open()\")\nrequires any inode be one of S_IFDIR/S_IFLNK/S_IFREG/S_IFCHR/S_IFBLK/\nS_IFIFO/S_IFSOCK type, use S_IFREG for $Extend records.","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":"ntfs3: pretend $Extend records as regular files","id":"CVE-2025-40313","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2025"},"n_packages":0,"n_references":6,"next":{"headline":"usb: cdns3: gadget: Use-after-free during failed initialization and exit of cdnsp gadget","id":"CVE-2025-40314"},"packages":[],"prev":{"headline":"jfs: Verify inode mode when loading from disk","id":"CVE-2025-40312"},"products":["Linux"],"published":"2025-12-08","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A flaw in the Linux kernel ntfs3 driver mishandles $Extend records, potentially causing system instability or crashes when accessing specific NTFS structures.","url":"https://insights.sbomify.com/CVE-2025-40313/"}
