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-2025-38136 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-2025-38136/ (Markdown: https://insights.sbomify.com/CVE-2025-38136/index.md)","id":"CVE-2025-38136","markdown":"https://insights.sbomify.com/CVE-2025-38136/index.md","name":"CVE-2025-38136","record":{"aliases":["AZL-64601","BELL-CVE-2025-38136","DEBIAN-CVE-2025-38136","GHSA-4xq6-m26v-vqpr","ROOT-OS-DEBIAN-11-CVE-2025-38136","ROOT-OS-DEBIAN-12-CVE-2025-38136","ROOT-OS-UBUNTU-2204-CVE-2025-38136","ROOT-OS-UBUNTU-2404-CVE-2025-38136","UBUNTU-CVE-2025-38136"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB driver","requires_auth":"low_privilege","summary":"A flaw in the Renesas USBHS driver causes a kernel crash during probe due to uninitialized clock access, leading to denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"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":[{"id":"CWE-908","name":"Use of Uninitialized Resource"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: renesas_usbhs: Reorder clock handling and power management in probe\n\nReorder the initialization sequence in `usbhs_probe()` to enable runtime\nPM before accessing registers, preventing potential crashes due to\nuninitialized clocks.\n\nCurrently, in the probe path, registers are accessed before enabling the\nclocks, leading to a synchronous external abort on the RZ/V2H SoC.\nThe problematic call flow is as follows:\n\n    usbhs_probe()\n        usbhs_sys_clock_ctrl()\n            usbhs_bset()\n                usbhs_write()\n                    iowrite16()  \u003c-- Register access before enabling clocks\n\nSince `iowrite16()` is performed without ensuring the required clocks are\nenabled, this can lead to access errors.
