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-2024-40917 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-2024-40917/ (Markdown: https://insights.sbomify.com/CVE-2024-40917/index.md)","id":"CVE-2024-40917","markdown":"https://insights.sbomify.com/CVE-2024-40917/index.md","name":"CVE-2024-40917","record":{"aliases":["BELL-CVE-2024-40917","DEBIAN-CVE-2024-40917","GHSA-pc8x-jh6x-8jfr","UBUNTU-CVE-2024-40917"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A null pointer dereference in the Linux kernel memblock subsystem can cause a system crash on specific NUMA configurations.","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\nmemblock: make memblock_set_node() also warn about use of MAX_NUMNODES\n\nOn an (old) x86 system with SRAT just covering space above 4Gb:\n\n    ACPI: SRAT: Node 0 PXM 0 [mem 0x100000000-0xfffffffff] hotplug\n\nthe commit referenced below leads to this NUMA configuration no longer\nbeing refused by a CONFIG_NUMA=y kernel (previously\n\n    NUMA: nodes only cover 6144MB of your 8185MB e820 RAM.
