CVE-2026-68359

Description

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.

Understanding the Weakness (CWE)

Confidentiality

Technical Impact: Read Memory

If the expired pointer is used in a read operation, an attacker might be able to control data read in by the application.

Availability

Technical Impact: DoS: Crash, Exit, or Restart

If the expired pointer references a memory location that is not accessible to the product, or points to a location that is "malformed" (such as NULL) or larger than expected by a read or write operation, then a crash may occur.

Integrity,Confidentiality,Availability

Technical Impact: Execute Unauthorized Code or Commands

If the expired pointer is used in a function call, or points to unexpected data in a write operation, then code execution may be possible.
