CVE-2026-46128 Details
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.
A vulnerability in the Linux kernel's IPMI (Intelligent Platform Management Interface) implementation has been addressed. The issue arose because the response data size from the event message buffer was not properly validated immediately after the response was received. Some Baseboard Management Controllers (BMCs) may return an empty message instead of an error when events are fetched. This vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed.
