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-2024-50130 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-2024-50130/ (Markdown: https://insights.sbomify.com/CVE-2024-50130/index.md)","id":"CVE-2024-50130","markdown":"https://insights.sbomify.com/CVE-2024-50130/index.md","name":"CVE-2024-50130","record":{"aliases":["AZL-52332","BELL-CVE-2024-50130","DEBIAN-CVE-2024-50130","GHSA-wqmj-2mp9-xqmr","UBUNTU-CVE-2024-50130"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel's netfilter BPF subsystem allows attackers to potentially execute code or escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: bpf: must hold reference on net namespace\n\nBUG: KASAN: slab-use-after-free in __nf_unregister_net_hook+0x640/0x6b0\nRead of size 8 at addr ffff8880106fe400 by task repro/72=\nbpf_nf_link_release+0xda/0x1e0\nbpf_link_free+0x139/0x2d0\nbpf_link_release+0x68/0x80\n__fput+0x414/0xb60\n\nEric says:\n It seems that bpf was able to defer the __nf_unregister_net_hook()\n after exit()/close() time.\n Perhaps a netns reference is missing, because the netns has been\n dismantled/freed already.\n bpf_nf_link_attach() does :\n link-\u003enet = net;\n But I do not see a reference being taken on net.\n\nAdd such a reference and release it after hook unreg.\nNote that I was unable to get syzbot reproducer to work, so I\ndo not know if this resolves this splat.","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":"netfilter: bpf: must hold reference on net namespace","id":"CVE-2024-50130","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"use_after_free","year":"2024"},"n_packages":0,"n_references":3,"next":{"headline":"tracing: Consider the NULL character when validating the event length","id":"CVE-2024-50131"},"packages":[],"prev":{"headline":"net: pse-pd: Fix out of bound for loop","id":"CVE-2024-50129"},"products":["Linux"],"published":"2024-11-05","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel's netfilter BPF subsystem allows attackers to potentially execute code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2024-50130/"}
