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(). The Linux kernel CVE team has assigned CVE-2026-68443 to this issue.

Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-68443 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/hwmon/gigabyte_waterforce.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/a855f678ba37ef82c4dd22926ad740ecfb8dbedf https://git.kernel.org/stable/c/f36e12cc8cfe996d627b8a82bd9df9e43270f6e2 https://git.kernel.org/stable/c/0842e9faab04f784d01125085195031252ff9695 https://git.kernel.org/stable/c/ff0c5c53d08274e200b48a4d53aa078265e873cb
