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-2025-6338 in the wild and no public exploit code.\n\nAffected product: Qt. 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-2025-6338/ (Markdown: https://insights.sbomify.com/CVE-2025-6338/index.md)","id":"CVE-2025-6338","markdown":"https://insights.sbomify.com/CVE-2025-6338/index.md","name":"CVE-2025-6338","record":{"aliases":["GHSA-m4hj-jpxf-jhjp"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Qt Network library","requires_auth":"none","summary":"An attacker can cause a denial of service on Windows Schannel-based servers by exploiting incomplete cleanup in Qt Network's TLS backend.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TQtC","cpe":[],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","version":"4.0"},"cwes":[{"id":"CWE-459","name":"Incomplete Cleanup"}],"description":"There is an incomplete cleanup vulnerability in Qt Network's Schannel support on Windows which can lead to a Denial of Service over a long period.\n\nThis issue affects Qt from 5.15.0 through 6.8.3, from 6.9.0 before 6.9.2.","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 denial of service with multiple incoming connections to a Schannel based server with a TLS backend","id":"CVE-2025-6338","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"ponaravindb Hospital Management System func3.php sql injection","id":"CVE-2025-6339"},"packages":[],"prev":{"headline":"TOTOLINK A3002R/A3002RU HTTP POST Request formTmultiAP buffer overflow","id":"CVE-2025-6337"},"products":["Qt"],"published":"2025-10-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-07-29","vendors":["Qt"]},"summary":"An attacker can cause a denial of service on Windows Schannel-based servers by exploiting incomplete cleanup in Qt Network's TLS backend.","url":"https://insights.sbomify.com/CVE-2025-6338/"}
