Y el problema parece ser que el grupo devres correspondiente no est\u00e1 asignado. Normalmente, devres_open_group() se llama desde __hid_device_probe() pero el controlador HID de Hyper-V anula 'hid_dev-&gt;driver' con el stub 'mousevsc_hid_driver' y b\u00e1sicamente vuelve a implementar __hid_device_probe() llamando a hid_parse() y hid_hw_start() pero no a devres_open_group(). hid_device_probe() no llama a __hid_device_probe() para ello. M\u00e1s tarde, cuando se elimina el controlador, hid_device_remove() llama a devres_release_group() ya que no verifica si hdev-&gt;driver se anul\u00f3 inicialmente o no. El problema parece estar relacionado con el commit 62c68e7cee33 (\"HID: garantizar la liberaci\u00f3n oportuna de los recursos asignados al controlador\") pero el commit en s\u00ed parece ser correcta. Solucione el problema eliminando la anulaci\u00f3n de 'hid_dev-&gt;driver' y utilizando hid_register_driver()/hid_unregister_driver() en su lugar. Como alternativa, habr\u00eda sido posible confiar en la gesti\u00f3n predeterminado, pero HID_CONNECT_DEFAULT implica HID_CONNECT_HIDRAW y no parece funcionar para mousevsc tal como est\u00e1."}], "id": "CVE-2024-56545", "lastModified": "2025-10-08T13:48:33.013", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 5.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "version": "3.1"}, "exploitabilityScore": 1.8, "impactScore": 3.6, "source": "nvd@nist.gov", "type": "Primary"}]}, "published": "2024-12-27T14:15:34.270", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/19a9457e5e210e408c1f8865b5d93c5a2c90409d"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/3d48d0fbaaa74a04fb9092780a3f83dc4f3f8160"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/66ef47faa90d838cda131fe1f7776456cc3b59f2"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/b03e713a400aeb5f969bab4daf47a7402d0df814"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "NVD-CWE-noinfo"}], "source": "nvd@nist.gov", "type": "Primary"}]}
