In the Linux kernel, the following vulnerability has been resolved: dm-verity: fix a possible NULL pointer dereference Fix a possible NULL pointer dereference dm_verity_loadpin_is_bdev_trusted if the device has no table.

A flaw was found in the Linux kernel's dm-verity component. A possible NULL pointer dereference can occur in the `dm_verity_loadpin_is_bdev_trusted` function if a device lacks a table. This vulnerability could allow a local attacker to cause a system crash, leading to a Denial of Service (DoS).
