Subject: vmwgfx: corruption in vmw_event_fence_action_create()
From: Dan Carpenter <[email protected]>
commit 68c4fce737c4b963e336435f225621dc21138397 upstream.
We don't allocate enough data for this struct. As soon as we start
modifying event->event on the next lines, then we're going beyond the
end of the memory we allocated.
