In the Linux kernel, the following vulnerability has been resolved:
ipmi: Check event message buffer response for bad data
The event message buffer response data size got checked later when
processing, but check it right after the response comes back. It
appears some BMCs may return an empty message instead of an error
when fetching events.
There are apparently some new BMCs that make this error, so we need to
compensate.
