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-2026-98526 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-2026-98526/ (Markdown: https://insights.sbomify.com/CVE-2026-98526/index.md)","id":"CVE-2026-98526","markdown":"https://insights.sbomify.com/CVE-2026-98526/index.md","name":"CVE-2026-98526","record":{"aliases":["AZL-108584","BELL-CVE-2026-98526","DEBIAN-CVE-2026-98526","GHSA-cxpq-4fh3-6276","UBUNTU-CVE-2026-98526"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A Linux kernel LLC frame allocation flaw allows attackers to cause headroom underflow, potentially leading to memory corruption or denial of service.","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\nllc: reserve device headroom for allocated frames\n\nllc_alloc_frame() reserves link-layer headroom using the device type.\nThis is insufficient for stacked Ethernet devices such as VLAN devices,\nwhere vlan_dev_hard_header() pushes a VLAN header before the lower\ndevice's Ethernet header.
