An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-39293 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-2024-39293/ (Markdown: https://insights.sbomify.com/CVE-2024-39293/index.md)","id":"CVE-2024-39293","markdown":"https://insights.sbomify.com/CVE-2024-39293/index.md","name":"CVE-2024-39293","record":{"aliases":["BELL-CVE-2024-39293","DEBIAN-CVE-2024-39293","GHSA-vhxr-pcmq-x8rc","ROOT-OS-UBUNTU-2204-CVE-2024-39293","ROOT-OS-UBUNTU-2404-CVE-2024-39293","UBUNTU-CVE-2024-39293"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A race condition in the Linux kernel's AF_XDP implementation allows concurrent access to Rx rings, leading to state corruption and kernel crashes.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nRevert \"xsk: Support redirect to any socket bound to the same umem\"\n\nThis reverts commit 2863d665ea41282379f108e4da6c8a2366ba66db.\n\nThis patch introduced a potential kernel crash when multiple napi instances\nredirect to the same AF_XDP socket.
