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-2024-35973 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2024-35973/ (Markdown: https://insights.sbomify.com/CVE-2024-35973/index.md)","id":"CVE-2024-35973","markdown":"https://insights.sbomify.com/CVE-2024-35973/index.md","name":"CVE-2024-35973","record":{"aliases":["BELL-CVE-2024-35973","DEBIAN-CVE-2024-35973","GHSA-hv5r-r2vq-gcrh","UBUNTU-CVE-2024-35973"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can trigger an uninitialized value read in the Linux kernel's GENEVE tunnel implementation, potentially leaking sensitive kernel memory.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","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-908","name":"Use of Uninitialized Resource"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ngeneve: fix header validation in geneve[6]_xmit_skb\n\nsyzbot is able to trigger an uninit-value in geneve_xmit() [1]\n\nProblem : While most ip tunnel helpers (like ip_tunnel_get_dsfield())\nuses skb_protocol(skb, true), pskb_inet_may_pull() is only using\nskb-\u003eprotocol.\n\nIf anything else than ETH_P_IPV6 or ETH_P_IP is found in skb-\u003eprotocol,\npskb_inet_may_pull() does nothing at all.\n\nIf a vlan tag was provided by the caller (af_packet in the syzbot case),\nthe network header might not point to the correct location, and skb\nlinear part could be smaller than expected.\n\nAdd skb_vlan_inet_prepare() to perform a complete mac validation.\n\nUse this in geneve for the moment, I suspect we need to adopt this\nmore broadly.\n\nv4 -
