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-2025-39685 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-2025-39685/ (Markdown: https://insights.sbomify.com/CVE-2025-39685/index.md)","id":"CVE-2025-39685","markdown":"https://insights.sbomify.com/CVE-2025-39685/index.md","name":"CVE-2025-39685","record":{"aliases":["AZL-66935","BELL-CVE-2025-39685","DEBIAN-CVE-2025-39685","GHSA-jx84-vrfm-c347","ROOT-OS-DEBIAN-11-CVE-2025-39685","ROOT-OS-DEBIAN-12-CVE-2025-39685","ROOT-OS-DEBIAN-13-CVE-2025-39685","ROOT-OS-UBUNTU-2204-CVE-2025-39685","ROOT-OS-UBUNTU-2404-CVE-2025-39685","UBUNTU-CVE-2025-39685"],"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 access in the pcl726 driver by passing an invalid IRQ number, causing a 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: pcl726: Prevent invalid irq number\n\nThe reproducer passed in an irq number(0x80008000) that was too large,\nwhich triggered the oob.\n\nAdded an interrupt number check to prevent users from passing in an irq\nnumber that was too large.\n\nIf `it-\u003eoptions[1]` is 31, then `1 \u003c\u003c it-\u003eoptions[1]` is still invalid\nbecause it shifts a 1-bit into the sign bit (which is UB in C).\nPossible solutions include reducing the upper bound on the\n`it-\u003eoptions[1]` value to 30 or lower, or using `1U \u003c\u003c it-\u003eoptions[1]`.\n\nThe old code would just not attempt to request the IRQ if the\n`options[1]` value were invalid.
