  3. CVE-2026-43079
In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: Skip discovery table for offline dies This warning can be triggered if NUMA is disabled and the system boots with fewer CPUs than the number of CPUs in die 0. WARNING: CPU: 9 PID: 7257 at uncore.c:1157 uncore_pci_pmu_register+0x136/0x160 [intel_uncore] Currently, the discovery table continues to be parsed even if all CPUs in the associated die are offline. This can lead to an array overflow at "pmu->boxes[die] = box" in uncore_pci_pmu_register(), which may trigger the warning above or cause other issues.
