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-2026-90116 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-2026-90116/ (Markdown: https://insights.sbomify.com/CVE-2026-90116/index.md)","id":"CVE-2026-90116","markdown":"https://insights.sbomify.com/CVE-2026-90116/index.md","name":"CVE-2026-90116","record":{"aliases":["AZL-102968","BELL-CVE-2026-90116","DEBIAN-CVE-2026-90116","GHSA-f6xw-5hrw-vj32","UBUNTU-CVE-2026-90116"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A race condition in the ALSA mtpav driver allows a use-after-free during card teardown, potentially causing a kernel crash.","user_interaction":"not_required","vuln_class":"race_condition"},"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: mtpav: shut down output timer before card teardown\n\nsnd_mtpav_output_timer() rearms chip-\u003etimer while holding\nchip-\u003espinlock and accesses the card-private mtpav state.\n\nsnd_mtpav_free() currently takes the same lock and calls\ntimer_delete() when the timer is active.
