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-2026-98285 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-2026-98285/ (Markdown: https://insights.sbomify.com/CVE-2026-98285/index.md)","id":"CVE-2026-98285","markdown":"https://insights.sbomify.com/CVE-2026-98285/index.md","name":"CVE-2026-98285","record":{"aliases":["AZL-106155","BELL-CVE-2026-98285","DEBIAN-CVE-2026-98285","GHSA-9v49-jvp7-mg86","UBUNTU-CVE-2026-98285"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel bridge","requires_auth":"high_privilege","summary":"A null pointer dereference in the Linux kernel bridge VLAN code can cause a system crash when switchdev deletion errors occur.","user_interaction":"not_required","vuln_class":"null_dereference"},"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: bridge: vlan: fix bugs caused by switchdev deletion errors\n\nAllowing switchdev to prevent vlan deletion and error out in __vlan_del\ncould cause multiple different issues - inconsistent state, memory leaks\nwhen flushing, NULL pointer dereference on bridge error when flushing.\nIt doesn't make sense to allow it to stop __vlan_del, so log the error\nand continue with software vlan deletion.
