CVE-2024-56545

Estado: ModificadaMedia (5.5)—

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:

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 está 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 básicamente 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. Más tarde, cuando se elimina el controlador, hid_device_remove() llama a devres_release_group() ya que no verifica si hdev-&gt;driver se anuló inicialmente o no. El problema parece estar relacionado con el commit 62c68e7cee33 (\"HID: garantizar la liberación oportuna de los recursos asignados al controlador\") pero el commit en sí parece ser correcta. Solucione el problema eliminando la anulación de 'hid_dev-&gt;driver' y utilizando hid_register_driver()/hid_unregister_driver() en su lugar. Como alternativa, habría sido posible confiar en la gestión predeterminado, pero HID_CONNECT_DEFAULT implica HID_CONNECT_HIDRAW y no parece funcionar para mousevsc tal como está."
