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-2023-54248 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-2023-54248/ (Markdown: https://insights.sbomify.com/CVE-2023-54248/index.md)","id":"CVE-2023-54248","markdown":"https://insights.sbomify.com/CVE-2023-54248/index.md","name":"CVE-2023-54248","record":{"aliases":["BELL-CVE-2023-54248","DEBIAN-CVE-2023-54248","GHSA-jf6q-v9m6-wc7j","UBUNTU-CVE-2023-54248"],"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 missing null check in the Linux kernel NTFS3 driver allows local attackers to cause a denial of service via null pointer dereference.","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: Add check for kmemdup\n\nSince the kmemdup may return NULL pointer,\nit should be better to add check for the return value\nin order to avoid NULL pointer dereference.","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: Add check for kmemdup","id":"CVE-2023-54248","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":5,"next":{"headline":"bus: mhi: ep: Only send -ENOTCONN status if client driver is available","id":"CVE-2023-54249"},"packages":[],"prev":{"headline":"bpf: Silence a warning in btf_type_id_size()","id":"CVE-2023-54247"},"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 missing null check in the Linux kernel NTFS3 driver allows local attackers to cause a denial of service via null pointer dereference.","url":"https://insights.sbomify.com/CVE-2023-54248/"}
