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-2024-26813 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-2024-26813/ (Markdown: https://insights.sbomify.com/CVE-2024-26813/index.md)","id":"CVE-2024-26813","markdown":"https://insights.sbomify.com/CVE-2024-26813/index.md","name":"CVE-2024-26813","record":{"aliases":["BELL-CVE-2024-26813","DEBIAN-CVE-2024-26813","GHSA-69h6-fpm9-fc3r","UBUNTU-CVE-2024-26813"],"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 NULL pointer dereference in the Linux kernel vfio-platform driver allows local attackers to cause a denial of service via loopback triggering.","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":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nvfio/platform: Create persistent IRQ handlers\n\nThe vfio-platform SET_IRQS ioctl currently allows loopback triggering of\nan interrupt before a signaling eventfd has been configured by the user,\nwhich thereby allows a NULL pointer dereference.\n\nRather than register the IRQ relative to a valid trigger, register all\nIRQs in a disabled state in the device open path.
