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-2024-26723 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-2024-26723/ (Markdown: https://insights.sbomify.com/CVE-2024-26723/index.md)","id":"CVE-2024-26723","markdown":"https://insights.sbomify.com/CVE-2024-26723/index.md","name":"CVE-2024-26723","record":{"aliases":["BELL-CVE-2024-26723","DEBIAN-CVE-2024-26723","GHSA-68q2-g7rv-mr2f","UBUNTU-CVE-2024-26723"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A null pointer dereference in the lan966x driver causes a kernel crash when adding an interface to a LAG, 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":7.8,"severity":"high","source":"cisa-adp","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-400","name":"Uncontrolled Resource Consumption"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nlan966x: Fix crash when adding interface under a lag\n\nThere is a crash when adding one of the lan966x interfaces under a lag\ninterface. The issue can be reproduced like this:\nip link add name bond0 type bond miimon 100 mode balance-xor\nip link set dev eth0 master bond0\n\nThe reason is because when adding a interface under the lag it would go\nthrough all the ports and try to figure out which other ports are under\nthat lag interface. And the issue is that lan966x can have ports that are\nNULL pointer as they are not probed. So then iterating over these ports\nit would just crash as they are NULL pointers.\nThe fix consists in actually checking for NULL pointers before accessing\nsomething from the ports.
