CVE-2023-53496

CVE-2023-53496 – In the Linux kernel, the UV (socketnode lookup) code loops over CPUs to build socket tables; when nr_cpus is less than actual CPUs, cpu_to_node() data for unused CPUs is missing, leading to -1 entries and potential oops. The fix replaces the CPU-loop with a loop over APICIDs mapp...
