Description
In the Linux kernel, the following vulnerability has been resolved: hwmon: (corsair-cpro) Remove debugfs entries when probe fails ccp_debugfs_init() registers debugfs files whose private data is the devm allocated ccp. If hwmon_device_register_with_info() fails right after it, ccp_probe() returns without removing them: the HID core then frees ccp, and ccp_remove() is not called for a failed probe, so the files stay behind. Reading one of them dereferences the freed pointer. Remove the debugfs entries on that error path. debugfs_remove_recursive() waits for readers already inside the show callbacks, so ccp is no longer reachable through debugfs by the time probe returns.
