Versions Affected : All verisons prior to FreeNAS 11.3-U3.2
mps(4) implements a pass-through interface which allows privileged user processes to submit commands directly to disks behind the controller.
A bug in the code which copies command results out to the requesting process could cause a kernel panic.
No workaround is available.
- Upgrade to FreeNAS 11.3-U4.1 or later.
