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-2026-98105 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-2026-98105/ (Markdown: https://insights.sbomify.com/CVE-2026-98105/index.md)","id":"CVE-2026-98105","markdown":"https://insights.sbomify.com/CVE-2026-98105/index.md","name":"CVE-2026-98105","record":{"aliases":["BELL-CVE-2026-98105","DEBIAN-CVE-2026-98105","GHSA-f226-mgwm-5x89","UBUNTU-CVE-2026-98105"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A flaw in the Linux kernel oa_tc6 ethernet driver allows remote attackers to cause a denial of service via buffer overflow errors during traffic oversubscription.","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\nnet: ethernet: oa_tc6: Improve the error recovery\n\nWhen oversubscribed traffic causes lot of buffer overflow errors,\nprobably due to loss of data chunks, driver fails to find a\ndata chunk with end_valid bit set, before it runs out of sk buffer\nspace.
