Versions Affected : All verisons prior to FreeNAS 11.3-U3.2


Description

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.


Workaround

No workaround is available.


Mitigation

  • Upgrade to FreeNAS 11.3-U4.1 or later.
