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-2025-54351 in the wild and no public exploit code.\n\nAffected product: ES iperf3. 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-2025-54351/ (Markdown: https://insights.sbomify.com/CVE-2025-54351/index.md)","id":"CVE-2025-54351","markdown":"https://insights.sbomify.com/CVE-2025-54351/index.md","name":"CVE-2025-54351","record":{"aliases":["ALPINE-CVE-2025-54351","BELL-CVE-2025-54351","GHSA-xjwm-4pfw-49g2","UBUNTU-CVE-2025-54351"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Network performance tool","requires_auth":"none","summary":"A buffer overflow in iperf3 allows attackers to execute code or cause denial of service when the skip-rx-copy option is enabled.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"iperf3","vendor":"es"}],"cvss":{"score":8.9,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-420","name":"Unprotected Alternate Channel"}],"description":"In iperf before 3.19.1, net.c has a buffer overflow when --skip-rx-copy is used (for MSG_TRUNC in recv).","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":"Memory corruption in iperf3","id":"CVE-2025-54351","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in WordPress","id":"CVE-2025-54352"},"packages":[],"prev":{"headline":"Denial of service in iperf3","id":"CVE-2025-54350"},"products":["iperf3"],"published":"2025-08-03","related":[{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2024-53580","kev_date_added":null,"published":"2024-12-18"},{"cvss_score":6.5,"headline":"Memory corruption in iperf3","id":"CVE-2025-54349","kev_date_added":null,"published":"2025-08-03"},{"cvss_score":5.9,"headline":"Information disclosure in n/a","id":"CVE-2024-26306","kev_date_added":null,"published":"2024-05-13"},{"cvss_score":5.3,"headline":"Iperf3: possible denial of service","id":"CVE-2023-7250","kev_date_added":null,"published":"2024-03-18"},{"cvss_score":3.7,"headline":"Denial of service in iperf3","id":"CVE-2025-54350","kev_date_added":null,"published":"2025-08-03"}],"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":"total"},"state":"PUBLISHED","updated":"2025-08-04","vendors":["ES"]},"summary":"A buffer overflow in iperf3 allows attackers to execute code or cause denial of service when the skip-rx-copy option is enabled.","url":"https://insights.sbomify.com/CVE-2025-54351/"}
