CVE-2024-26768

CVE-2024-26768 affects the Linux kernel LoongArch path: the patch changes the ACPI core PIC array from [NR_CPUS] to [MAX_CORE_PIC] to match the MADT max physical CPUs. With NR_CPUS defaulting to 64, platforms with more than 64 CPUs could overflow acpi_core_pic when parsing MADT, risking a boot cr...

CVE-2024-26768 LoongArch: Change acpi_core_pic[NR_CPUS] to acpi_core_pic[MAX_CORE_PIC]

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Change acpicorepicNRCPUS to acpicorepicMAXCOREPIC With default config, the value of NRCPUS is 64. When HW platform has more then 64 cpus, system will crash on these platforms. MAXCOREPIC is the maximum cpu number in MA...
