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-2025-40136 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-2025-40136/ (Markdown: https://insights.sbomify.com/CVE-2025-40136/index.md)","id":"CVE-2025-40136","markdown":"https://insights.sbomify.com/CVE-2025-40136/index.md","name":"CVE-2025-40136","record":{"aliases":["BELL-CVE-2025-40136","DEBIAN-CVE-2025-40136","GHSA-p5f2-4xpv-wwqj","ROOT-OS-DEBIAN-12-CVE-2025-40136","ROOT-OS-DEBIAN-13-CVE-2025-40136","ROOT-OS-UBUNTU-2404-CVE-2025-40136","UBUNTU-CVE-2025-40136"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A missing interrupt registration in the Hisilicon QM driver causes a kernel warning and potential instability when virtual functions are passed through to VMs with GICv4 enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\ncrypto: hisilicon/qm - request reserved interrupt for virtual function\n\nThe device interrupt vector 3 is an error interrupt for\nphysical function and a reserved interrupt for virtual function.\nHowever, the driver has not registered the reserved interrupt for\nvirtual function.
