Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-98485 in the wild and no public exploit code.\n\nAffected product: 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-2026-98485/ (Markdown: https://insights.sbomify.com/CVE-2026-98485/index.md)","id":"CVE-2026-98485","markdown":"https://insights.sbomify.com/CVE-2026-98485/index.md","name":"CVE-2026-98485","record":{"aliases":["AZL-108650","BELL-CVE-2026-98485","DEBIAN-CVE-2026-98485","GHSA-mhfj-849g-frgh","UBUNTU-CVE-2026-98485"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel netfilter","requires_auth":"low_privilege","summary":"A crafted IPv6 packet can trigger an out-of-bounds read in the Linux kernel netfilter module, causing a kernel panic or information disclosure.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: ip6t_rt: fix zero-address non-strict match out-of-bounds read\n\nrt_mt6_check() permits rules to be configured with rtinfo-\u003eaddrnr == 0\neven when address matching (IP6T_RT_FST_MASK) is requested.\n\nIn the IP6T_RT_FST_NSTRICT path, rt_mt6() evaluates packet routing\naddresses against rtinfo-\u003eaddrs[i] and terminates backwards at the bottom\nof the loop:\n\n    if (ipv6_addr_equal(ap, \u0026rtinfo-\u003eaddrs[i])) {\n        i++;\n    }\n    if (i == rtinfo-\u003eaddrnr)\n        break;\n\nWhen addrnr is 0, if the first packet address matches rtinfo-\u003eaddrs[0],\ni is incremented to 1.
