CVE-2026-68361
Description
A flaw was found in the Linux kernel's hwmon (corsair-psu) module. A race condition exists where the hid_hw_stop() function fails to stop device input/output (I/O) operations before memory is deallocated. This can occur during the corsairpsu_probe() failure path, allowing the hid_input_report() function to access memory that has already been freed. This use-after-free vulnerability could allow a local attacker to cause a system crash (denial of service) or potentially execute arbitrary code.
Understanding the Weakness (CWE)
Integrity,Availability,Confidentiality
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; Execute Unauthorized Code or Commands
This weakness may result in the corruption of memory, and perhaps instructions, possibly leading to a crash. If the corrupted memory can be effectively controlled, it may be possible to execute arbitrary code.
