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-2023-4163 in the wild and no public exploit code.\n\nAffected product: Broadcom Fabric Operating System. 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-2023-4163/ (Markdown: https://insights.sbomify.com/CVE-2023-4163/index.md)","id":"CVE-2023-4163","markdown":"https://insights.sbomify.com/CVE-2023-4163/index.md","name":"CVE-2023-4163","record":{"aliases":["GHSA-cfpg-6fr3-9x4g"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Brocade Fabric OS","requires_auth":"high_privilege","summary":"A local privileged user can cause a kernel panic via buffer overflow in the portcfgfportbuffers command, requiring an upgrade to Brocade Fabric OS.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"brocade","cpe":[{"product":"fabric_operating_system","vendor":"broadcom"}],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"In\n Brocade Fabric OS before v9.2.0a, a local authenticated privileged user\n can trigger a buffer overflow condition, leading to a kernel panic with\n large input to buffers in the portcfgfportbuffers command.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Possible buffer overflow in portcfgfportbuffers in Brocade Fabric OS","id":"CVE-2023-4163","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"broadcom:fabric_operating_system","products":["broadcom:fabric_operating_system"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"There is a possible information disclosure due to a missing permission check in Pixel Watch","id":"CVE-2023-4164"},"packages":[],"prev":{"headline":"Segmentation fault in Brocade Fabric OS after Brocade Fabric OS v9.0","id":"CVE-2023-4162"},"products":["Brocade Fabric OS"],"published":"2023-08-31","related":[{"cvss_score":8.6,"headline":"Broadcom Brocade Fabric OS Code Injection","id":"CVE-2025-1976","kev_date_added":"2025-04-28","published":"2025-04-24"},{"cvss_score":8.3,"headline":"Linux Kernel Heap Out-of-Bounds Write","id":"CVE-2021-22555","kev_date_added":"2025-10-06","published":"2021-07-07"},{"cvss_score":9.8,"headline":"Command injection in Brocade Fabric OS","id":"CVE-2022-33186","kev_date_added":null,"published":"2022-12-08"},{"cvss_score":9.8,"headline":"Hardcoded credentials in Brocade Fabric OS","id":"CVE-2021-27797","kev_date_added":null,"published":"2022-02-21"},{"cvss_score":9.8,"headline":"Code injection in Brocade Fabric OS","id":"CVE-2020-15371","kev_date_added":null,"published":"2020-09-25"},{"cvss_score":9.8,"headline":"Memory corruption in Brocade Fabric OS","id":"CVE-2020-15373","kev_date_added":null,"published":"2020-09-25"},{"cvss_score":9.8,"headline":"Cross-site scripting in Brocade Fabric OS","id":"CVE-2020-15374","kev_date_added":null,"published":"2020-09-25"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-06-26","vendors":["Brocade"]},"summary":"A local privileged user can cause a kernel panic via buffer overflow in the portcfgfportbuffers command, requiring an upgrade to Brocade Fabric OS.","url":"https://insights.sbomify.com/CVE-2023-4163/"}
