CVE-2026-43143

In the Linux kernel, CVE-2026-43143 fixes a concurrency issue in the multi-function device (mfd) core: access/modification of the mfd_of_node_list was not mutex-protected, risking unsafe list manipulation and potential crashes. The fix adds a mutex to guard this list, reducing crash likelihood. P...
