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-2025-40107 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-2025-40107/ (Markdown: https://insights.sbomify.com/CVE-2025-40107/index.md)","id":"CVE-2025-40107","markdown":"https://insights.sbomify.com/CVE-2025-40107/index.md","name":"CVE-2025-40107","record":{"aliases":["AZL-69586","BELL-CVE-2025-40107","DEBIAN-CVE-2025-40107","GHSA-394x-fq64-jqf6","ROOT-OS-DEBIAN-11-CVE-2025-40107","ROOT-OS-DEBIAN-12-CVE-2025-40107","ROOT-OS-DEBIAN-13-CVE-2025-40107","ROOT-OS-UBUNTU-2204-CVE-2025-40107","ROOT-OS-UBUNTU-2404-CVE-2025-40107","UBUNTU-CVE-2025-40107"],"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":"none","summary":"A null pointer dereference in the Linux kernel hi311x CAN driver causes a denial of service when resuming from sleep before the interface is enabled.","user_interaction":"not_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\ncan: hi311x: fix null pointer dereference when resuming from sleep before interface was enabled\n\nThis issue is similar to the vulnerability in the `mcp251x` driver,\nwhich was fixed in commit 03c427147b2d (\"can: mcp251x: fix resume from\nsleep before interface was brought up\").\n\nIn the `hi311x` driver, when the device resumes from sleep, the driver\nschedules `priv-\u003erestart_work`. However, if the network interface was\nnot previously enabled, the `priv-\u003ewq` (workqueue) is not allocated and\ninitialized, leading to a null pointer dereference.\n\nTo fix this, we move the allocation and initialization of the workqueue\nfrom the `hi3110_open` function to the `hi3110_can_probe` function.\nThis ensures that the workqueue is properly initialized before it is\nused during device resume.
