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-2026-93080 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-2026-93080/ (Markdown: https://insights.sbomify.com/CVE-2026-93080/index.md)","id":"CVE-2026-93080","markdown":"https://insights.sbomify.com/CVE-2026-93080/index.md","name":"CVE-2026-93080","record":{"aliases":["BELL-CVE-2026-93080","DEBIAN-CVE-2026-93080","GHSA-mj5f-93r8-jjjp","UBUNTU-CVE-2026-93080"],"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":"A flaw in the Linux kernel SCMI driver allows malformed firmware to cause a denial of service during device teardown.","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\nfirmware: arm_scmi: Fix transport device teardown lookup\n\nSCMI transport devices are deliberately excluded from normal SCMI bus\nmatching so protocol drivers cannot bind to the internal transport\nchildren. However, scmi_device_destroy() uses the same protocol/name\nlookup to find devices that must be unregistered during channel teardown.\n\nSplit the match helper so driver matching still skips transport devices,\nwhile explicit child lookup can find them for teardown.
