CVE-2026-46128
CVE-2026-46128
Description
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.
