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-2026-45860 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-45860/ (Markdown: https://insights.sbomify.com/CVE-2026-45860/index.md)","id":"CVE-2026-45860","markdown":"https://insights.sbomify.com/CVE-2026-45860/index.md","name":"CVE-2026-45860","record":{"aliases":["BELL-CVE-2026-45860","DEBIAN-CVE-2026-45860","GHSA-xwf3-wjqg-p85x","ROOT-OS-DEBIAN-11-CVE-2026-45860","ROOT-OS-UBUNTU-2204-CVE-2026-45860","ROOT-OS-UBUNTU-2404-CVE-2026-45860","UBUNTU-CVE-2026-45860"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Linux kernel netfilter","requires_auth":"none","summary":"Attackers can cause connection tracking limits to be reached prematurely, leading to service unavailability in Linux kernel netfilter configurations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_conncount: increase the connection clean up limit to 64\n\nAfter the optimization to only perform one GC per jiffy, a new problem\nwas introduced.
