The device is left started.\n\nThe HID core does not unwind on the driver's behalf. __hid_device_probe()\nreleases the devres group, closes the report and clears hdev->driver:\n\n\tif (ret) {\n\t\tdevres_release_group(&hdev->dev, hdev->devres_group_id);\n\t\thid_close_report(hdev);\n\t\thdev->driver = NULL;\n\t}\n\nThe hidraw character device that hid_hw_start() registered through\nhid_connect() is allocated with kzalloc() and added with cdev_device_add(),\nso it is not devres-managed and survives that. With hdev->driver NULL,\nhid_device_remove() skips hid_hw_stop() as well, because it only unwinds\nwhile a driver is still attached. The registration therefore outlives the\ndevice on both paths.\n\nOpening the surviving /dev/hidrawX writes into freed memory. KASAN reports\na use-after-free write from hidraw_open() -> hid_hw_open() -> the\ntransport's open callback, which takes a spinlock inside the freed object.\nA descriptor that carries a PID usage page and no input reports is enough:\nhidraw claims the device so hid_hw_start() succeeds, while hid->inputs\nstays empty so force-feedback init fails. The other failure returns in\nhid_pidff_init_with_quirks() - no output reports, an allocation failure,\npidff_init_fields(), pidff_check_autocenter(), an unusable effect count,\ninput_ff_create() - all reach the same label.\n\nStop the device on that path. hid-dr.c and hid-emsff.c, which start the\ndevice with the same HID_CONNECT_DEFAULT & ~HID_CONNECT_FF mask, already do\nthis. The two earlier gotos must keep returning without hid_hw_stop(),\nsince neither has a started device, so give the path that fails after the\nstart its own label.\n\nDiscovered by XBOW, triaged by Baul Lee ", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "c1fde337b317f0a226de92803288741c30799eb0", "status": "affected", "versionType": "git", "lessThan": "66358f5789c9a7e28809985a83c01e6ad933849e" }, { "version": "f45f26a6b3e7260c129c7c6bb0ace63aeb7b3868", "status": "affected", "versionType": "git", "lessThan": "519fa26695b02870022fcdc651efb3d379abe54e" }, { "version": "f06bf8d94fffbb544b1cb5402c92e0a075f0d420", "status": "affected", "versionType": "git", "lessThan": "01d9874e84d3ab78fd212ad822412eb3af84497f" }, { "version": "f06bf8d94fffbb544b1cb5402c92e0a075f0d420", "status": "affected", "versionType": "git", "lessThan": "c457bb516b61edeab940235a011928e26925381e" }, { "version": "f06bf8d94fffbb544b1cb5402c92e0a075f0d420", "status": "affected", "versionType": "git", "lessThan": "ce08c5555cabcd444d8b77fa69a7cb68bb05f611" }, { "version": "af9f2471dfe5a48384f5b7f021a673fbc741465e", "status": "affected", "versionType": "git" }, { "version": "b797352954eee6dc084cfaed0659dea60adfb484", "status": "affected", "versionType": "git" }, { "version": "6.6.88", "status": "affected", "versionType": "semver", "lessThan": "6.6.160" }, { "version": "6.12.24", "status": "affected", "versionType": "semver", "lessThan": "6.12.111" }, { "version": "6.13.12", "status": "affected", "versionType": "semver", "lessThan": "6.14" }, { "version": "6.14.3", "status": "affected", "versionType": "semver", "lessThan": "6.15" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "6.15", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "6.15" }, { "version": "6.6.160", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.6.*" }, { "version": "6.12.111", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.12.*" }, { "version": "6.18.50", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.18.*" }, { "version": "7.2.4", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "7.2.*" }, { "version": "7.3", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
