Description

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