NVD Description

In the Linux kernel, the following vulnerability has been resolved:

dm-integrity: fix a bug if the bio is out of limits

If dm_integrity_check_limits fails, the code would exit with DM_MAPIO_KILL. However, the range would be already locked at this point, and it wouldn't be unlocked, resulting in a deadlock. Let's move the limit check up, so that when it exits, no resources are leaked.
