CVE-2026-46327

   
Software afectado LINUX KERNEL
 
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.
