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-2026-98428 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-2026-98428/ (Markdown: https://insights.sbomify.com/CVE-2026-98428/index.md)","id":"CVE-2026-98428","markdown":"https://insights.sbomify.com/CVE-2026-98428/index.md","name":"CVE-2026-98428","record":{"aliases":["AZL-108123","BELL-CVE-2026-98428","DEBIAN-CVE-2026-98428","GHSA-xcw2-5vfj-h3fm","UBUNTU-CVE-2026-98428"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel USB 6fire driver allows local attackers to execute arbitrary code or escalate privileges via physical USB access.","user_interaction":"not_required","vuln_class":"use_after_free"},"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\nALSA: usb: 6fire: Avoid embedded URBs\n\nThe USB 6fire driver uses URBs embedded in different structs for PCM,\nMIDI and communication, and this is basically a buggy implementation\nnowadays; since a URB is managed with a refcount, this may lead to a\nUAF when the URB is released asynchronously.\n\nFor addressing the problem, this patch converts those embedded URBs to\nones that are properly allocated via usb_alloc_urb().
