## Overview

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.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
