Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> dm: fix unlocked test for dm_suspended_md<br /> <br /> The function dm_blk_report_zones tests if the device is suspended with<br /> the "dm_suspended_md" call. However, this function is called without<br /> holding any locks, so the device may be suspended just after it.<br /> <br /> Move the call to dm_suspended_md after dm_get_live_table, so that the<br /> device can&amp;#39;t be suspended after the suspended state was tested.
