It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-40085 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-2025-40085/ (Markdown: https://insights.sbomify.com/CVE-2025-40085/index.md)","id":"CVE-2025-40085","markdown":"https://insights.sbomify.com/CVE-2025-40085/index.md","name":"CVE-2025-40085","record":{"aliases":["AZL-69030","BELL-CVE-2025-40085","DEBIAN-CVE-2025-40085","GHSA-2cjq-ppmx-48x5","ROOT-OS-DEBIAN-12-CVE-2025-40085","ROOT-OS-DEBIAN-13-CVE-2025-40085","ROOT-OS-UBUNTU-2204-CVE-2025-40085","ROOT-OS-UBUNTU-2404-CVE-2025-40085","UBUNTU-CVE-2025-40085"],"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 local attacker with physical access can cause a kernel crash by connecting a malicious USB audio device, leading to denial of service.","user_interaction":"required","vuln_class":"null_dereference"},"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-audio: Fix NULL pointer deference in try_to_register_card\n\nIn try_to_register_card(), the return value of usb_ifnum_to_if() is\npassed directly to usb_interface_claimed() without a NULL check, which\nwill lead to a NULL pointer dereference when creating an invalid\nUSB audio device.
