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-2025-38530 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-2025-38530/ (Markdown: https://insights.sbomify.com/CVE-2025-38530/index.md)","id":"CVE-2025-38530","markdown":"https://insights.sbomify.com/CVE-2025-38530/index.md","name":"CVE-2025-38530","record":{"aliases":["AZL-66389","BELL-CVE-2025-38530","DEBIAN-CVE-2025-38530","GHSA-j2mv-rj6m-hq85","ROOT-OS-DEBIAN-11-CVE-2025-38530","ROOT-OS-DEBIAN-12-CVE-2025-38530","ROOT-OS-DEBIAN-13-CVE-2025-38530","ROOT-OS-UBUNTU-2204-CVE-2025-38530","ROOT-OS-UBUNTU-2404-CVE-2025-38530","UBUNTU-CVE-2025-38530"],"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":"low_privilege","summary":"A local attacker can trigger an out-of-bounds bit shift in the PCL812 driver, potentially causing a kernel crash or denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncomedi: pcl812: Fix bit shift out of bounds\n\nWhen checking for a supported IRQ number, the following test is used:\n\n\tif ((1 \u003c\u003c it-\u003eoptions[1]) \u0026 board-\u003eirq_bits) {\n\nHowever, `it-\u003eoptions[i]` is an unchecked `int` value from userspace, so\nthe shift amount could be negative or out of bounds.
