Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，以下漏洞已被修复： hwmon: (corsair-cpro) 在 probe 失败时移除 debugfs 条目 ccp_debugfs_init() 函数会注册一些 debugfs 文件，这些文件的私有数据指向通过 devm 分配的 ccp 结构体。如果紧接着调用 hwmon_device_register_with_info() 失败，ccp_probe() 函数会直接返回，而没有移除这些 debugfs 文件：随后 HID 核心会释放 ccp 资源，且由于 probe 失败，ccp_r

Vulnerability Title
hwmon: (corsair-cpro) Remove debugfs entries when probe fails
Source: CVE Program / CVE List V5
Vulnerability 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.
