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.", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "e6ea3de7abef998aaab9f04a7a11a7c5f56bbe57", "status": "affected", "versionType": "git", "lessThan": "b7c074d21fe8a8ee3b4f866a12c72cad6a5826eb" }, { "version": "ac0d8318082f549419104cfe9cb6a9deb2df9853", "status": "affected", "versionType": "git", "lessThan": "4c419126cf71ca1f358ec0b8ccc448928719d502" }, { "version": "4d1617e40713a6202b6165ca137b09aaf35637f5", "status": "affected", "versionType": "git", "lessThan": "a216f6dc0444c3bd900bca66b9f21467d08e3ed3" }, { "version": "62c68e7cee332e08e625af3bca3318814086490d", "status": "affected", "versionType": "git", "lessThan": "b03e713a400aeb5f969bab4daf47a7402d0df814" }, { "version": "62c68e7cee332e08e625af3bca3318814086490d", "status": "affected", "versionType": "git", "lessThan": "19a9457e5e210e408c1f8865b5d93c5a2c90409d" }, { "version": "62c68e7cee332e08e625af3bca3318814086490d", "status": "affected", "versionType": "git", "lessThan": "3d48d0fbaaa74a04fb9092780a3f83dc4f3f8160" }, { "version": "62c68e7cee332e08e625af3bca3318814086490d", "status": "affected", "versionType": "git", "lessThan": "66ef47faa90d838cda131fe1f7776456cc3b59f2" }, { "version": "5.10.270", "status": "affected", "versionType": "semver", "lessThan": "5.10.271" }, { "version": "5.15.221", "status": "affected", "versionType": "semver", "lessThan": "5.15.222" }, { "version": "6.1.188", "status": "affected", "versionType": "semver", "lessThan": "6.1.189" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "6.5", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "6.5" }, { "version": "5.10.271", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.10.*" }, { "version": "5.15.222", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.15.*" }, { "version": "6.1.189", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.1.*" }, { "version": "6.6.64", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.6.*" }, { "version": "6.11.11", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.11.*" }, { "version": "6.12.2", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.12.*" }, { "version": "6.13", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
