Description
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.
