Title
HID: hyperv: streamline driver probe to avoid devres issues
Summary
In the Linux kernel, the following vulnerability has been resolved: HID: hyperv: streamline driver probe to avoid devres issues It was found that unloading 'hid_hyperv' module results in a devres complaint: ... hv_vmbus: unregistering driver hid_hyperv ------------[ cut here ]------------ WARNING: CPU: 2 PID: 3983 at drivers/base/devres.c:691 devres_release_group+0x1f2/0x2c0 ... Call Trace: <TASK> ? devres_release_group+0x1f2/0x2c0 ? __warn+0xd1/0x1c0 ? devres_release_group+0x1f2/0x2c0 ? report_bug+0x32a/0x3c0 ? handle_bug+0x53/0xa0 ? exc_invalid_op+0x18/0x50 ? asm_exc_invalid_op+0x1a/0x20 ? devres_release_group+0x1f2/0x2c0 ? devres_release_group+0x90/0x2c0 ? rcu_is_watching+0x15/0xb0 ? __pfx_devres_release_group+0x10/0x10 hid_device_remove+0xf5/0x220 device_release_driver_internal+0x371/0x540 ? klist_put+0xf3/0x170 bus_remove_device+0x1f1/0x3f0 device_del+0x33f/0x8c0 ? __pfx_device_del+0x10/0x10 ? cleanup_srcu_struct+0x337/0x500 hid_destroy_device+0xc8/0x130 mousevsc_remove+0xd2/0x1d0 [hid_hyperv] device_release_driver_internal+0x371/0x540 driver_detach+0xc5/0x180 bus_remove_driver+0x11e/0x2a0 ? __mutex_unlock_slowpath+0x160/0x5e0 vmbus_driver_unregister+0x62/0x2b0 [hv_vmbus] ... And the issue seems to be that the corresponding devres group is not allocated. Normally, devres_open_group() is called from __hid_device_probe() but Hyper-V HID driver overrides 'hid_dev->driver' with 'mousevsc_hid_driver' stub and basically re-implements __hid_device_probe() by calling hid_parse() and hid_hw_start() but not devres_open_group(). hid_device_probe() does not call __hid_device_probe() for it. Later, when the driver is removed, hid_device_remove() calls devres_release_group() as it doesn't check whether hdev->driver was initially overridden or not. The issue seems to be related to the commit 62c68e7cee33 ("HID: ensure timely release of driver-allocated resources") but the commit itself seems to be correct. Fix the issue by dropping the 'hid_dev->driver' override and using hid_register_driver()/hid_unregister_driver() instead. Alternatively, it would have been possible to rely on the default handling but HID_CONNECT_DEFAULT implies HID_CONNECT_HIDRAW and it doesn't seem to work for mousevsc as-is.

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 \u0027hid_dev-\u0026gt;driver\u0027 con el stub \u0027mousevsc_hid_driver\u0027 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-\u0026gt;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 \u0027hid_dev-\u0026gt;driver\u0027 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.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":5.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"NVD-CWE-noinfo\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.5\",\"versionEndExcluding\":\"6.6.64\",\"matchCriteriaId\":\"54B7846B-C7F0-4910-8749-C0C31DCDDFD7\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.7\",\"versionEndExcluding\":\"6.11.11\",\"matchCriteriaId\":\"21434379-192D-472F-9B54-D45E3650E893\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.12\",\"versionEndExcluding\":\"6.12.2\",\"matchCriteriaId\":\"D8882B1B-2ABC-4838-AC1D-DBDBB5764776\"}]}]}],\"references\":[{\"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\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]}]}}"
