An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-32746 exists.\n\nAffected product: GNU inetutils. 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-2026-32746/ (Markdown: https://insights.sbomify.com/CVE-2026-32746/index.md)","id":"CVE-2026-32746","markdown":"https://insights.sbomify.com/CVE-2026-32746/index.md","name":"CVE-2026-32746","record":{"aliases":["DEBIAN-CVE-2026-32746","GHSA-qvfm-56cp-4988","MGASA-2026-0122","SUSE-SU-2026:0930-1","UBUNTU-CVE-2026-32746","openSUSE-SU-2026:10657-1","openSUSE-SU-2026:20374-1"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GNU inetutils telnetd","requires_auth":"none","summary":"An out-of-bounds write in GNU inetutils telnetd allows 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":"mitre","cpe":[{"product":"inetutils","vendor":"gnu"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"telnetd in GNU inetutils through 2.7 allows an out-of-bounds write in the LINEMODE SLC (Set Local Characters) suboption handler because add_slc does not check whether the buffer is full.","ecosystems":["SUSE:Linux Enterprise Server 12 SP5-LTSS","SUSE:Linux Enterprise Server LTSS Extended Security 12 SP5","openSUSE:Leap 16.0","openSUSE:Tumbleweed"],"exploits":{"exploitdb":1,"first_seen":"2026-03-18","github_poc":7,"max_poc_stars":30,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-03-18T12:37:30Z","kind":"github_poc","ref":"https://github.com/jeffaf/cve-2026-32746","stars":30,"title":"CVE-2026-32746 - GNU InetUtils telnetd LINEMODE SLC Buffer Overflow PoC (pre-auth RCE, CVSS 9.8)"},{"date":"2026-03-19T14:58:34Z","kind":"github_poc","ref":"https://github.com/watchtowrlabs/watchtowr-vs-telnetd-CVE-2026-32746","stars":10,"title":null},{"date":"2026-08-02T22:44:47Z","kind":"github_poc","ref":"https://github.com/MonkeySeC-sys/Kangaroo","stars":2,"title":"Kangaroo is a exploit built on CVE-2026-32746.  i made this for security researchers, IT professionals, DevOps. so they can understand it better.
