medium Tenable Cloud Security Plugin ID 470260

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2026-46128)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.224.7 or later.
