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-2025-38246 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-2025-38246/ (Markdown: https://insights.sbomify.com/CVE-2025-38246/index.md)","id":"CVE-2025-38246","markdown":"https://insights.sbomify.com/CVE-2025-38246/index.md","name":"CVE-2025-38246","record":{"aliases":["AZL-64835","BELL-CVE-2025-38246","DEBIAN-CVE-2025-38246","GHSA-26c6-3rj3-7q4h","ROOT-OS-DEBIAN-12-CVE-2025-38246","ROOT-OS-UBUNTU-2404-CVE-2025-38246","UBUNTU-CVE-2025-38246"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel network driver","requires_auth":"none","summary":"A memory corruption bug in the bnxt network driver causes a kernel crash when processing XDP redirects, leading to denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbnxt: properly flush XDP redirect lists\n\nWe encountered following crash when testing a XDP_REDIRECT feature\nin production:\n\n[56251.579676] list_add corruption. next-\u003eprev should be prev (ffff93120dd40f30), but was ffffb301ef3a6740.
