It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-4647 in the wild and no public exploit code.\n\nAffected product: Gnu Binutils. 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-2026-4647/ (Markdown: https://insights.sbomify.com/CVE-2026-4647/index.md)","id":"CVE-2026-4647","markdown":"https://insights.sbomify.com/CVE-2026-4647/index.md","name":"CVE-2026-4647","record":{"aliases":["AZL-80877","AZL-80895","AZL-80904","DEBIAN-CVE-2026-4647","ECHO-6de7-bed5-044a","GHSA-v858-p3pc-hqjh","MINI-8gj9-8g26-8www","UBUNTU-CVE-2026-4647"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU Binutils BFD library","requires_auth":"none","summary":"Attackers can cause crashes or leak memory by providing crafted XCOFF files to tools using the GNU Binutils BFD library.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"binutils","vendor":"gnu"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"openshift_container_platform","vendor":"redhat"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables. The issue occurs when processing specially crafted XCOFF object files, where a relocation type value is not properly validated before being used. This can cause the program to read memory outside of intended bounds. As a result, affected tools may crash or expose unintended memory contents, leading to denial-of-service or limited information disclosure risks.","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":"Binutils: out-of-bounds read in xcoff relocation processing in gnu binutils bfd library","id":"CVE-2026-4647","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:binutils","products":["gnu:binutils","redhat:enterprise_linux","redhat:openshift_container_platform"],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Insufficient Encryption Level in CasfID Servicios Tecnológicos NFC Wristbands","id":"CVE-2026-4648"},"packages":[],"prev":{"headline":"Insufficient input validation in GitHub plugin API causes denial of service","id":"CVE-2026-4646"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 6","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9","Red Hat Hardened Images","Red Hat OpenShift Container Platform 4"],"published":"2026-03-23","related":[{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2017-7614","kev_date_added":null,"published":"2017-04-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2014-9939","kev_date_added":null,"published":"2017-03-21"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2017-7226","kev_date_added":null,"published":"2017-03-22"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2017-6969","kev_date_added":null,"published":"2017-03-17"},{"cvss_score":8.8,"headline":"Denial of service in n/a","id":"CVE-2020-19726","kev_date_added":null,"published":"2023-08-22"},{"cvss_score":7.8,"headline":"Binutils: binutils: arbitrary code execution via malformed xcoff object file processing","id":"CVE-2026-6846","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2022-44840","kev_date_added":null,"published":"2023-08-22"}],"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":"2026-09-01","vendors":["Red Hat"]},"summary":"Attackers can cause crashes or leak memory by providing crafted XCOFF files to tools using the GNU Binutils BFD library.","url":"https://insights.sbomify.com/CVE-2026-4647/"}
