Description
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.
