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