## Overview

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.

## Affected

- `Linux >= fb0987682c629c1d2c476f35f6fde405a5e304a4 < f7989286175f32db8605e767a1a2efc62e894dc8`
- `Linux >= fb0987682c629c1d2c476f35f6fde405a5e304a4 < aa5113e7155f4ea81d2c0303ab5cb272d4b32627`
- `Linux >= fb0987682c629c1d2c476f35f6fde405a5e304a4 < 3d1afaa074622859678b1a1e7c1b9c0af74c89b0`
- `Linux >= fb0987682c629c1d2c476f35f6fde405a5e304a4 < 5a266764fadaff8b5c1fe37a186ebf9b09cb953e`
- `Linux 6.11`
