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-2023-54264 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-2023-54264/ (Markdown: https://insights.sbomify.com/CVE-2023-54264/index.md)","id":"CVE-2023-54264","markdown":"https://insights.sbomify.com/CVE-2023-54264/index.md","name":"CVE-2023-54264","record":{"aliases":["BELL-CVE-2023-54264","DEBIAN-CVE-2023-54264","GHSA-vrgf-cf4x-v6w6","UBUNTU-CVE-2023-54264"],"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":"low_privilege","summary":"A null pointer dereference in the Linux kernel SysV filesystem allows local attackers to cause a denial of service.","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/sysv: Null check to prevent null-ptr-deref bug\n\nsb_getblk(inode-\u003ei_sb, parent) return a null ptr and taking lock on\nthat leads to the null-ptr-deref bug.","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/sysv: Null check to prevent null-ptr-deref bug","id":"CVE-2023-54264","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":8,"next":{"headline":"ipv6: Fix an uninit variable access bug in __ip6_make_skb()","id":"CVE-2023-54265"},"packages":[],"prev":{"headline":"drm/nouveau/kms/nv50-: init hpd_irq_lock for PIOR DP","id":"CVE-2023-54263"},"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 SysV filesystem allows local attackers to cause a denial of service.","url":"https://insights.sbomify.com/CVE-2023-54264/"}
