CVE-2024-26768

The CVE-2024-26768 issue affects the Linux kernel LoongArch ACPI MADT handling. The root cause was an overflow of acpi_core_pic[NR_CPUS] when the MADT table includes more CPUs than NR_CPUS (default NR_CPUS=64). The patch defines the array as acpi_core_pic[MAX_CORE_PIC] to match physical cores, pr...
