Summary
In the Linux kernel, the following vulnerability has been resolved: LoongArch: Change acpi_core_pic[NR_CPUS] to acpi_core_pic[MAX_CORE_PIC] With default config, the value of NR_CPUS is 64. When HW platform has more then 64 cpus, system will crash on these platforms. MAX_CORE_PIC is the maximum cpu number in MADT table (max physical number) which can exceed the supported maximum cpu number (NR_CPUS, max logical number), but kernel should not crash. Kernel should boot cpus with NR_CPUS, let the remainder cpus stay in BIOS. The potential crash reason is that the array acpi_core_pic[NR_CPUS] can be overflowed when parsing MADT table, and it is obvious that CORE_PIC should be corresponding to physical core rather than logical core, so it is better to define the array as acpi_core_pic[MAX_CORE_PIC]. With the patch, system can boot up 64 vcpus with qemu parameter -smp 128, otherwise system will crash with the following message.

Cuando la plataforma HW tiene m\u00e1s de 64 cpus, el SYSTEM fallar\u00e1 en estas plataformas . MAX_CORE_PIC es el n\u00famero m\u00e1ximo de CPU en la tabla MADT (n\u00famero f\u00edsico m\u00e1ximo) que puede exceder el n\u00famero m\u00e1ximo de CPU admitido (NR_CPUS, n\u00famero l\u00f3gico m\u00e1ximo), pero el kernel no deber\u00eda fallar. El kernel debe arrancar los procesadores con NR_CPUS y dejar que los procesadores restantes permanezcan en el BIOS. La posible raz\u00f3n del fallo es que la matriz acpi_core_pic[NR_CPUS] puede desbordarse al analizar la tabla MADT, y es obvio que CORE_PIC debe corresponder al n\u00facleo f\u00edsico en lugar del n\u00facleo l\u00f3gico, por lo que es mejor definir la matriz como acpi_core_pic[MAX_CORE_PIC] . Con el parche, el SYSTEM puede iniciar 64 vcpus con el par\u00e1metro qemu -smp 128; de lo contrario, el SYSTEM fallar\u00e1 con el siguiente mensaje.
