CVE-2026-43344

A flaw was found in the Linux kernel's performance monitoring unit perf/x86/intel/uncore subsystem. This vulnerability arises from incorrect die ID initialization and lookup, particularly when certain CPUs are offline or when Non-Uniform Memory Access NUMA is disabled. As a consequence, performan...
