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-2026-74624 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-2026-74624/ (Markdown: https://insights.sbomify.com/CVE-2026-74624/index.md)","id":"CVE-2026-74624","markdown":"https://insights.sbomify.com/CVE-2026-74624/index.md","name":"CVE-2026-74624","record":{"aliases":["AZL-97152","BELL-CVE-2026-74624","DEBIAN-CVE-2026-74624","GHSA-3q82-j896-jqw7","UBUNTU-CVE-2026-74624"],"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":"A deadlock in the Linux kernel netfilter subsystem can cause a denial of service when invalid packet logging is enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_conntrack: defer invalid log until after unlock\n\nTCP and SCTP conntrack paths can emit invalid-packet logs while ct-\u003elock\nis still held.\n\nWhen invalid logging is routed to nfnetlink_log and conntrack export is\nenabled, the log path can re-enter conntrack netlink glue and dump the\nsame conntrack again.
