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-2024-47703 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-2024-47703/ (Markdown: https://insights.sbomify.com/CVE-2024-47703/index.md)","id":"CVE-2024-47703","markdown":"https://insights.sbomify.com/CVE-2024-47703/index.md","name":"CVE-2024-47703","record":{"aliases":["AZL-51182","AZL-51275","BELL-CVE-2024-47703","DEBIAN-CVE-2024-47703","GHSA-h5ph-x8j2-r7vg","ROOT-OS-DEBIAN-11-CVE-2024-47703","ROOT-OS-DEBIAN-12-CVE-2024-47703","ROOT-OS-UBUNTU-2204-CVE-2024-47703","UBUNTU-CVE-2024-47703"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A BPF LSM program returning a positive value causes a kernel panic, leading to denial of service.","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":7.8,"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf, lsm: Add check for BPF LSM return value\n\nA bpf prog returning a positive number attached to file_alloc_security\nhook makes kernel panic.\n\nThis happens because file system can not filter out the positive number\nreturned by the LSM prog using IS_ERR, and misinterprets this positive\nnumber as a file pointer.\n\nGiven that hook file_alloc_security never returned positive number\nbefore the introduction of BPF LSM, and other BPF LSM hooks may\nencounter similar issues, this patch adds LSM return value check\nin verifier, to ensure no unexpected value is returned.","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":"bpf, lsm: Add check for BPF LSM return value","id":"CVE-2024-47703","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":3,"next":{"headline":"drm/amd/display: Check link_res-\u003ehpo_dp_link_enc before using it","id":"CVE-2024-47704"},"packages":[],"prev":{"headline":"bpf: Fail verification for sign-extension of packet data/data_end/data_meta","id":"CVE-2024-47702"},"products":["Linux"],"published":"2024-10-21","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A BPF LSM program returning a positive value causes a kernel panic, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2024-47703/"}
