Subject: [Patch 0/2] QuarkSocPkg/QncSmmDispatcher: Fix SMI Handler ASSERTs()
Date: Wed, 5 Oct 2016 11:28:48 -0700 [thread overview]
Message-ID: <1475692130-20756-1-git-send-email-michael.d.kinney@intel.com> (raw)
This series fixes the following two issues:
QuarkSocPkg QncSmmDispatcher passes incorrect context to SMI handler
https://bugzilla.tianocore.org/show_bug.cgi?id=136
QuarkSockg Use after free in QNCSmmCoreDispatcher
https://bugzilla.tianocore.org/show_bug.cgi?id=51
These issues can be reproduced using the unit test available in the following
branch that registers a periodic SMI that is triggered every 8 seconds and
unregisters itself after the periodic SMI handler has been triggered 4 times.
