Summary
In the Linux kernel, the following vulnerability has been resolved: hwmon: (nzxt-kraken3) Stop device IO before calling hid_hw_stop Calling hid_hw_stop() does not stop the device IO. This results in a race condition between hid_input_report() and the point immediately following the execution of hid_device_io_start() within the driver probe function.
If the probe operation fails after "io start" has been initiated, this race condition will result in a UAF vulnerability. Fix the problem by calling hid_device_io_stop() before calling hid_hw_stop().
A race condition exists where the `hid_hw_stop()` function does not stop device input/output (IO). This can lead to a use-after-free (UAF) vulnerability if a device probe operation fails after IO has been initiated.
This vulnerability could allow a local attacker to potentially cause a denial of service or escalate privileges. Red Hat severity: Moderate — CVSS 4.1 (CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H).
