Vulnerability from github – Published: 2026-08-12 00:31 – Updated: 2026-08-12 00:31

Details

In the Linux kernel, the following vulnerability has been resolved:

hwmon: (gigabyte_waterforce) 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().

Title

hwmon: (gigabyte_waterforce) Stop device IO before calling hid_hw_stop

Summary

In the Linux kernel, the following vulnerability has been resolved: hwmon: (gigabyte_waterforce) 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().
