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-2022-48785 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-2022-48785/ (Markdown: https://insights.sbomify.com/CVE-2022-48785/index.md)","id":"CVE-2022-48785","markdown":"https://insights.sbomify.com/CVE-2022-48785/index.md","name":"CVE-2022-48785","record":{"aliases":["DEBIAN-CVE-2022-48785","GHSA-j7cj-9mpv-gjcc","UBUNTU-CVE-2022-48785"],"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":"none","summary":"A race condition in the Linux kernel IPv6 multicast code can cause a general protection fault, leading to system crashes or stalls.","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":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-667","name":"Improper Locking"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nipv6: mcast: use rcu-safe version of ipv6_get_lladdr()\n\nSome time ago 8965779d2c0e (\"ipv6,mcast: always hold idev-\u003elock before mca_lock\")\nswitched ipv6_get_lladdr() to __ipv6_get_lladdr(), which is rcu-unsafe\nversion.
