In the Linux kernel, the following vulnerability has been resolved:
bus: fsl-mc: fix use-after-free in driver_override_show()
The driver_override_show() function reads the driver_override string without holding the device_lock. However, driver_override_store() uses driver_set_override(), which modifies and frees the string while holding the device_lock.
This can result in a concurrent use-after-free if the string is freed by the store function while being read by the show function.
Fix this by holding the device_lock around the read operation.
