CVE-2026-46128

ipmi: Check event message buffer response for bad data

State: Published
Severity: Not scored
Published: May 28, 2026
Updated: Oct 15, 2026
Reserved: May 13, 2026

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.
