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-2024-43835 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-2024-43835/ (Markdown: https://insights.sbomify.com/CVE-2024-43835/index.md)","id":"CVE-2024-43835","markdown":"https://insights.sbomify.com/CVE-2024-43835/index.md","name":"CVE-2024-43835","record":{"aliases":["AZL-51969","AZL-51995","BELL-CVE-2024-43835","DEBIAN-CVE-2024-43835","GHSA-vgj5-hqjj-6hcj","UBUNTU-CVE-2024-43835"],"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 bug in the Linux kernel's virtio_net driver causes a warning and potential instability when handling network packets outside of NAPI context.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nvirtio_net: Fix napi_skb_cache_put warning\n\nAfter the commit bdacf3e34945 (\"net: Use nested-BH locking for\nnapi_alloc_cache.\") was merged, the following warning began to appear:\n\n\t WARNING: CPU: 5 PID: 1 at net/core/skbuff.c:1451 napi_skb_cache_put+0x82/0x4b0\n\n\t  __warn+0x12f/0x340\n\t  napi_skb_cache_put+0x82/0x4b0\n\t  napi_skb_cache_put+0x82/0x4b0\n\t  report_bug+0x165/0x370\n\t  handle_bug+0x3d/0x80\n\t  exc_invalid_op+0x1a/0x50\n\t  asm_exc_invalid_op+0x1a/0x20\n\t  __free_old_xmit+0x1c8/0x510\n\t  napi_skb_cache_put+0x82/0x4b0\n\t  __free_old_xmit+0x1c8/0x510\n\t  __free_old_xmit+0x1c8/0x510\n\t  __pfx___free_old_xmit+0x10/0x10\n\nThe issue arises because virtio is assuming it's running in NAPI context\neven when it's not, such as in the netpoll case.\n\nTo resolve this, modify virtnet_poll_tx() to only set NAPI when budget\nis available.
