Description

A flaw was found in the Linux kernel's device mapper (dm) component. The `dm_blk_report_zones` function performs a check for the device's suspended state without proper locking. This allows the device to enter a suspended state immediately after the check, leading to an inconsistent state. This inconsistency could potentially result in unexpected system behavior or a denial of service (DoS) condition.
