A use-after-free vulnerability in the Linux kernel's fsl-mc bus driver was fixed by ensuring proper locking in the driver_override_show() function. The issue arises because driver_override_show() reads a string without holding the device_lock, while driver_override_store() modifies and frees the string under the device_lock, potentially causing concurrent use-after-free. This vulnerability is part of a broader set of Linux kernel security fixes addressing multiple subsystems. A patch is available and users should update to the fixed kernel versions and reboot to apply the changes.
