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-2023-54272 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-2023-54272/ (Markdown: https://insights.sbomify.com/CVE-2023-54272/index.md)","id":"CVE-2023-54272","markdown":"https://insights.sbomify.com/CVE-2023-54272/index.md","name":"CVE-2023-54272","record":{"aliases":["BELL-CVE-2023-54272","DEBIAN-CVE-2023-54272","GHSA-jm7j-xgrw-fv67","UBUNTU-CVE-2023-54272"],"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 null-pointer dereference in the Linux kernel NTFS3 driver allows local attackers to cause a system crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\nfs/ntfs3: Fix a possible null-pointer dereference in ni_clear()\n\nIn a previous commit c1006bd13146, ni-\u003emi.mrec in ni_write_inode()\ncould be NULL, and thus a NULL check is added for this variable.\n\nHowever, in the same call stack, ni-\u003emi.mrec can be also dereferenced\nin ni_clear():\n\nntfs_evict_inode(inode)\n  ni_write_inode(inode, ...)\n    ni = ntfs_i(inode);\n    is_rec_inuse(ni-\u003emi.mrec) -\u003e Add a NULL check by previous commit\n  ni_clear(ntfs_i(inode))\n    is_rec_inuse(ni-\u003emi.mrec) -\u003e No check\n\nThus, a possible null-pointer dereference may exist in ni_clear().\nTo fix it, a NULL check is added in this function.","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: Fix a possible null-pointer dereference in ni_clear()","id":"CVE-2023-54272","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"xfrm: Fix leak of dev tracker","id":"CVE-2023-54273"},"packages":[],"prev":{"headline":"blk-cgroup: Fix NULL deref caused by blkg_policy_data being installed before init","id":"CVE-2023-54271"},"products":["Linux"],"published":"2025-12-30","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 null-pointer dereference in the Linux kernel NTFS3 driver allows local attackers to cause a system crash.","url":"https://insights.sbomify.com/CVE-2023-54272/"}
