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...

CVE-2023-53496 x86/platform/uv: Use alternate source for socket to node data

In the Linux kernel, the following vulnerability has been resolved: x86/platform/uv: Use alternate source for socket to node data The UV code attempts to build a set of tables to allow it to do bidirectional socketnode lookups. But when nrcpus is set to a smaller number than actually present, the...
