In the Linux kernel, the following vulnerability has been resolved: dm: fix NULL pointer dereference in dmsuspend There is a race condition between dm device suspend and table load that can lead to null pointer dereference. The issue occurs when suspend is invoked before table load completes: BUG...

Vulnerability of the __dm_internal_suspend() function in the drivers/md/dm.c module – The driver for supporting multiple devices (RAID and LVM) in the Linux kernel allows an attacker to compromise the confidentiality, integrity, and accessibility of protected information.
