Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix page_size variable overflow Change all variables storing mlx5_umem_mkc_find_best_pgsz() result to unsigned long to support values larger than 31 and avoid overflow. For example: If we try to register 4GB of memory that is contiguous in physical memory, the driver will optimize the page_size and try to use an mkey with 4GB entity size. The 'unsigned int' page_size variable will overflow to '0' and we'll hit the WARN_ON() in alloc_cacheable_mr().
