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.

Text
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.
