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-2023-54105 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-2023-54105/ (Markdown: https://insights.sbomify.com/CVE-2023-54105/index.md)","id":"CVE-2023-54105","markdown":"https://insights.sbomify.com/CVE-2023-54105/index.md","name":"CVE-2023-54105","record":{"aliases":["BELL-CVE-2023-54105","DEBIAN-CVE-2023-54105","GHSA-pg9h-x33j-cfq7","ROOT-OS-UBUNTU-2204-CVE-2023-54105","ROOT-OS-UBUNTU-2404-CVE-2023-54105","UBUNTU-CVE-2023-54105"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel CAN","requires_auth":"low_privilege","summary":"A missing check in the Linux kernel CAN ISOTP module allows binding with incorrect address families, potentially leading to unexpected behavior or information leakage.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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\ncan: isotp: check CAN address family in isotp_bind()\n\nAdd missing check to block non-AF_CAN binds.\n\nSyzbot created some code which matched the right sockaddr struct size\nbut used AF_XDP (0x2C) instead of AF_CAN (0x1D) in the address family\nfield:\n\nbind$xdp(r2, \u0026(0x7f0000000540)={0x2c, 0x0, r4, 0x0, r2}, 0x10)\n                                ^^^^\nThis has no funtional impact but the userspace should be notified about\nthe wrong address family field content.","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":"can: isotp: check CAN address family in isotp_bind()","id":"CVE-2023-54105","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2023"},"n_packages":0,"n_references":5,"next":{"headline":"net/mlx5: fix potential memory leak in mlx5e_init_rep_rx","id":"CVE-2023-54106"},"packages":[],"prev":{"headline":"mtd: rawnand: fsl_upm: Fix an off-by one test in fun_exec_op()","id":"CVE-2023-54104"},"products":["Linux"],"published":"2025-12-24","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 check in the Linux kernel CAN ISOTP module allows binding with incorrect address families, potentially leading to unexpected behavior or information leakage.","url":"https://insights.sbomify.com/CVE-2023-54105/"}
