An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-52558 in the wild and no public exploit code.\n\nAffected product: Openbsd Openbsd. 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-2023-52558/ (Markdown: https://insights.sbomify.com/CVE-2023-52558/index.md)","id":"CVE-2023-52558","markdown":"https://insights.sbomify.com/CVE-2023-52558/index.md","name":"CVE-2023-52558","record":{"aliases":["GHSA-4cg8-w873-pfqx"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenBSD kernel","requires_auth":"none","summary":"A remote attacker can crash the OpenBSD kernel by sending specially crafted network packets, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisa-cg","cpe":[{"product":"openbsd","vendor":"openbsd"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-131","name":"Incorrect Calculation of Buffer Size"}],"description":"In OpenBSD 7.4 before errata 002 and OpenBSD 7.3 before errata 019, a network buffer that had to be split at certain length that could crash the kernel after receiving specially crafted escape sequences.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"OpenBSD 7.4 and 7.3 m_split() network buffer kernel crash","id":"CVE-2023-52558","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openbsd:openbsd","products":["openbsd:openbsd"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"iommu/vt-d: Avoid memory allocation in iommu_suspend()","id":"CVE-2023-52559"},"packages":[],"prev":{"headline":"OpenBSD 7.3 invalid l2tp message npppd crash","id":"CVE-2023-52557"},"products":["OpenBSD"],"published":"2024-03-01","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-1365","kev_date_added":null,"published":"2007-03-10"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2004-0220","kev_date_added":null,"published":"2004-03-25"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0083","kev_date_added":null,"published":"2004-02-14"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0084","kev_date_added":null,"published":"2004-02-14"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2001-0284","kev_date_added":null,"published":"2001-05-07"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2000-1010","kev_date_added":null,"published":"2001-01-22"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2020-16088","kev_date_added":null,"published":"2020-07-28"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-19","vendors":["OpenBSD"]},"summary":"A remote attacker can crash the OpenBSD kernel by sending specially crafted network packets, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2023-52558/"}
