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":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/hid/hid-hyperv.c"],"versions":[{"version":"62c68e7cee332e08e625af3bca3318814086490d","lessThan":"b03e713a400aeb5f969bab4daf47a7402d0df814","status":"affected","versionType":"git"},{"version":"62c68e7cee332e08e625af3bca3318814086490d","lessThan":"19a9457e5e210e408c1f8865b5d93c5a2c90409d","status":"affected","versionType":"git"},{"version":"62c68e7cee332e08e625af3bca3318814086490d","lessThan":"3d48d0fbaaa74a04fb9092780a3f83dc4f3f8160","status":"affected","versionType":"git"},{"version":"62c68e7cee332e08e625af3bca3318814086490d","lessThan":"66ef47faa90d838cda131fe1f7776456cc3b59f2","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/hid/hid-hyperv.c"],"versions":[{"version":"6.5","status":"affected"},{"version":"0","lessThan":"6.5","status":"unaffected","versionType":"semver"},{"version":"6.6.64","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.11.11","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12.2","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.13","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5","versionEndExcluding":"6.6.64"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5","versionEndExcluding":"6.11.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5","versionEndExcluding":"6.12.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5","versionEndExcluding":"6.13"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/b03e713a400aeb5f969bab4daf47a7402d0df814"},{"url":"https://git.kernel.org/stable/c/19a9457e5e210e408c1f8865b5d93c5a2c90409d"},{"url":"https://git.kernel.org/stable/c/3d48d0fbaaa74a04fb9092780a3f83dc4f3f8160"},{"url":"https://git.kernel.org/stable/c/66ef47faa90d838cda131fe1f7776456cc3b59f2"}],"title":"HID: hyperv: streamline driver probe to avoid devres issues","x_generator":{"engine":"bippy-1.2.0"}}}}
