CVE-2026-43079

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