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-2024-26783 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-2024-26783/ (Markdown: https://insights.sbomify.com/CVE-2024-26783/index.md)","id":"CVE-2024-26783","markdown":"https://insights.sbomify.com/CVE-2024-26783/index.md","name":"CVE-2024-26783","record":{"aliases":["BELL-CVE-2024-26783","DEBIAN-CVE-2024-26783","GHSA-2pv2-gg54-r8f4","ROOT-OS-DEBIAN-12-CVE-2024-26783","UBUNTU-CVE-2024-26783"],"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 local attacker can trigger a kernel crash by exploiting a null pointer dereference in the memory management subsystem when NUMA balancing is enabled on systems with nodes lacking local memory.","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\nmm/vmscan: fix a bug calling wakeup_kswapd() with a wrong zone index\n\nWith numa balancing on, when a numa system is running where a numa node\ndoesn't have its local memory so it has no managed zones, the following\noops has been observed.
