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-2025-38481 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2025-38481/ (Markdown: https://insights.sbomify.com/CVE-2025-38481/index.md)","id":"CVE-2025-38481","markdown":"https://insights.sbomify.com/CVE-2025-38481/index.md","name":"CVE-2025-38481","record":{"aliases":["AZL-65922","BELL-CVE-2025-38481","DEBIAN-CVE-2025-38481","GHSA-wm2g-6m3r-4fx9","ROOT-OS-DEBIAN-11-CVE-2025-38481","ROOT-OS-DEBIAN-12-CVE-2025-38481","ROOT-OS-UBUNTU-2204-CVE-2025-38481","ROOT-OS-UBUNTU-2404-CVE-2025-38481","UBUNTU-CVE-2025-38481"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel comedi","requires_auth":"low_privilege","summary":"A local attacker can trigger a kernel warning and stack dump by supplying an excessively large instruction count to the comedi ioctl, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncomedi: Fail COMEDI_INSNLIST ioctl if n_insns is too large\n\nThe handling of the `COMEDI_INSNLIST` ioctl allocates a kernel buffer to\nhold the array of `struct comedi_insn`, getting the length from the\n`n_insns` member of the `struct comedi_insnlist` supplied by the user.\nThe allocation will fail with a WARNING and a stack dump if it is too\nlarge.\n\nAvoid that by failing with an `-EINVAL` error if the supplied `n_insns`\nvalue is unreasonable.\n\nDefine the limit on the `n_insns` value in the `MAX_INSNS` macro.
