It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-26634 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-2024-26634/ (Markdown: https://insights.sbomify.com/CVE-2024-26634/index.md)","id":"CVE-2024-26634","markdown":"https://insights.sbomify.com/CVE-2024-26634/index.md","name":"CVE-2024-26634","record":{"aliases":["BELL-CVE-2024-26634","DEBIAN-CVE-2024-26634","GHSA-7rx6-7rmx-f3hf","UBUNTU-CVE-2024-26634"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel networking","requires_auth":"low_privilege","summary":"A bug in Linux kernel networking causes a crash when removing a network namespace with conflicting interface altnames, leading to denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/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\nnet: fix removing a namespace with conflicting altnames\n\nMark reports a BUG() when a net namespace is removed.\n\n    kernel BUG at net/core/dev.c:11520!\n\nPhysical interfaces moved outside of init_net get \"refunded\"\nto init_net when that namespace disappears.
