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-2026-93280 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-2026-93280/ (Markdown: https://insights.sbomify.com/CVE-2026-93280/index.md)","id":"CVE-2026-93280","markdown":"https://insights.sbomify.com/CVE-2026-93280/index.md","name":"CVE-2026-93280","record":{"aliases":["BELL-CVE-2026-93280","DEBIAN-CVE-2026-93280","GHSA-mwmc-pxhm-4fx8","UBUNTU-CVE-2026-93280"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A malicious Greybus module can trigger out-of-bounds reads in the Linux kernel audio driver by providing inconsistent topology section sizes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ngreybus: audio: bound the topology section sizes against the fetched size\n\ngb_audio_gb_get_topology() fetches a topology blob of a module-supplied\nsize, and gbaudio_tplg_parse_data() then walks it by adding the\nmodule-supplied size_dais, size_controls and size_widgets fields to\nform the control, widget and route section offsets.
