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-2026-68476 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-68476/ (Markdown: https://insights.sbomify.com/CVE-2026-68476/index.md)","id":"CVE-2026-68476","markdown":"https://insights.sbomify.com/CVE-2026-68476/index.md","name":"CVE-2026-68476","record":{"aliases":["BELL-CVE-2026-68476","DEBIAN-CVE-2026-68476","GHSA-3fqj-wv67-hq22","UBUNTU-CVE-2026-68476"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel IPVS","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel IPVS module allows attackers to execute arbitrary code or cause a denial of service.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nipvs: reload ip header after head reallocation\n\n__ip_vs_get_out_rt() calls skb_ensure_writable() which may\nreallocate skb-\u003ehead.","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":"ipvs: reload ip header after head reallocation","id":"CVE-2026-68476","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"ipvs: fix more places with wrong ipv6 transport offsets","id":"CVE-2026-68477"},"packages":[],"prev":{"headline":"reset: sunxi: fix memory region leak on ioremap failure","id":"CVE-2026-68475"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-09-02","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel IPVS module allows attackers to execute arbitrary code or cause a denial of service.","url":"https://insights.sbomify.com/CVE-2026-68476/"}
