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-2026-68161 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-2026-68161/ (Markdown: https://insights.sbomify.com/CVE-2026-68161/index.md)","id":"CVE-2026-68161","markdown":"https://insights.sbomify.com/CVE-2026-68161/index.md","name":"CVE-2026-68161","record":{"aliases":["AZL-94950","BELL-CVE-2026-68161","DEBIAN-CVE-2026-68161","GHSA-9g3f-gj9q-hqjj","UBUNTU-CVE-2026-68161"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Linux kernel","requires_auth":"none","summary":"Attackers can cause a denial of service by tearing down network namespaces while SCTP UDP tunnel sockets remain active, requiring specific sysctl configuration.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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":[{"id":"CWE-404","name":"Improper Resource Shutdown or Release"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: close UDP tunnel sockets during netns teardown\n\nproc_sctp_do_udp_port() starts per-net SCTP UDP tunneling sockets when\nnet.sctp.udp_port is set, and stops/restarts them when the sysctl value\nchanges.
