Summary
A flaw was found in the Linux kernel's hwmon (nzxt-smart2) component. A race condition exists when the `hid_hw_stop()` function is called without first stopping device input/output (IO).
If a device probe operation fails after IO has been initiated, this race condition can lead to a use-after-free (UAF) vulnerability. This could allow a local attacker to potentially cause a system crash (denial of service) or achieve arbitrary code execution.
Red Hat severity: not rated. Weakness: CWE-825.
Red Hat lists Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected.
