In the Linux kernel, the following vulnerability has been resolved:

dm: fix unlocked test for dm suspended md

The function dm blk report zones tests if the device is suspended with the "dm suspended md" call. However, this function is called without holding any locks, so the device may be suspended just after it.

Move the call to dm suspended md after dm get live table, so that the device can't be suspended after the suspended state was tested.
