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-2026-68359 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/hwmon/nzxt-smart2.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/185c0880397aee9def0af5a59ea65f22f37ad658 https://git.kernel.org/stable/c/a2a15de020597efbff84b4281dd472e5860b7e3e https://git.kernel.org/stable/c/205cff797a94757ec88ba299c8e2bf2e1e3f4bbf https://git.kernel.org/stable/c/18d7c523891004226bccdba39dd681eca22ceb8a https://git.kernel.org/stable/c/59d104b54b0b42e30fd2a68d24ee5c49dcc54d1e
