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-2026-98089 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-2026-98089/ (Markdown: https://insights.sbomify.com/CVE-2026-98089/index.md)","id":"CVE-2026-98089","markdown":"https://insights.sbomify.com/CVE-2026-98089/index.md","name":"CVE-2026-98089","record":{"aliases":["AZL-104669","BELL-CVE-2026-98089","DEBIAN-CVE-2026-98089","GHSA-3x47-v429-xjvw","UBUNTU-CVE-2026-98089"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An attacker can trigger out-of-bounds memory access in the Linux kernel bonding driver via crafted ICMPv6 packets, potentially causing a crash or code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbonding: alb: fix uninitialized transport header access in alb_determine_nd()\n\nalb_determine_nd() uses icmp6_hdr(skb) to inspect ICMPv6 headers.\nHowever, in xmit paths (e.g. packets sent via AF_PACKET / raw sockets\nor forwarded packets), skb-\u003etransport_header is not guaranteed to be\ninitialized.
