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-2023-54312 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-2023-54312/ (Markdown: https://insights.sbomify.com/CVE-2023-54312/index.md)","id":"CVE-2023-54312","markdown":"https://insights.sbomify.com/CVE-2023-54312/index.md","name":"CVE-2023-54312","record":{"aliases":["BELL-CVE-2023-54312","DEBIAN-CVE-2023-54312","GHSA-p36c-jp35-qgrh","UBUNTU-CVE-2023-54312"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel sample","requires_auth":"none","summary":"A buffer overflow in the Linux kernel's tcp_basertt sample allows local attackers to execute arbitrary code or cause a denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nsamples/bpf: Fix buffer overflow in tcp_basertt\n\nUsing sizeof(nv) or strlen(nv)+1 is correct.","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":"samples/bpf: Fix buffer overflow in tcp_basertt","id":"CVE-2023-54312","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":8,"next":{"headline":"ovl: fix null pointer dereference in ovl_get_acl_rcu()","id":"CVE-2023-54313"},"packages":[],"prev":{"headline":"ext4: fix deadlock when converting an inline directory in nojournal mode","id":"CVE-2023-54311"},"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 buffer overflow in the Linux kernel's tcp_basertt sample allows local attackers to execute arbitrary code or cause a denial of service.","url":"https://insights.sbomify.com/CVE-2023-54312/"}
