Summary
In the Linux kernel, the dm-integrity module has a bug that can lead to a deadlock. When dm_integrity_check_limits fails, the code exits with DM_MAPIO_KILL, but the range is already locked and not unlocked. The fix moves the limit check earlier to avoid resource leaks.
Risk Assessment
The risk includes the possibility of system deadlock, which could lead to unresponsiveness and disruption of services.
Recommendation
It is recommended to apply the Linux kernel patch that moves the limit check before locking the range to prevent deadlocks.
Original NVD description (English source)
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.
