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-2026-89949 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-2026-89949/ (Markdown: https://insights.sbomify.com/CVE-2026-89949/index.md)","id":"CVE-2026-89949","markdown":"https://insights.sbomify.com/CVE-2026-89949/index.md","name":"CVE-2026-89949","record":{"aliases":["AZL-101319","BELL-CVE-2026-89949","DEBIAN-CVE-2026-89949","GHSA-95x9-5832-jchc","UBUNTU-CVE-2026-89949"],"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":"An unaligned memory access in the batman-adv kernel module can cause a system crash, requiring a kernel patch to fix.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nbatman-adv: dat: avoid unaligned fault in IP extraction\n\nIndependent of the alignment of the ARP packet in the SKB, either the\nbatadv_arp_ip_src or the batadv_arp_ip_dst will have an unaligned access\n(on HW without native unaligned read support).\n\nUse get_unaligned() to handle this properly on all architectures.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"batman-adv: dat: avoid unaligned fault in IP extraction","id":"CVE-2026-89949","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"batman-adv: mcast: linearize skbuff for packet generation","id":"CVE-2026-89950"},"packages":[],"prev":{"headline":"batman-adv: bla: fix freeing of claims on meshif deletion","id":"CVE-2026-89948"},"products":["Linux"],"published":"2026-09-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"An unaligned memory access in the batman-adv kernel module can cause a system crash, requiring a kernel patch to fix.","url":"https://insights.sbomify.com/CVE-2026-89949/"}
