CVE-2026-43150

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> perf/arm-cmn: Reject unsupported hardware configurations<br /> <br /> So far we&amp;#39;ve been fairly lax about accepting both unknown CMN models<br /> (at least with a warning), and unknown revisions of those which we<br /> do know, as although things do frequently change between releases,<br /> typically enough remains the same to be somewhat useful for at least<br /> some basic bringup checks. However, we also make assumptions of the<br /> maximum supported sizes and numbers of things in various places, and<br /> there&amp;#39;s no guarantee that something new might not be bigger and lead<br /> to nasty array overflows. Make sure we only try to run on things that<br /> actually match our assumptions and so will not risk memory corruption.<br /> <br /> We have at least always failed on completely unknown node types, so<br /> update that error message for clarity and consistency too.
