In the Linux kernel, the following vulnerability has been resolved: RDMA/umem: Be careful about boundary conditions in ib_umem_find_best_pgsz() Several corner cases, especially important on 32 bits: - umem->iova is u64, the function argument should pass in u64 or iova will be truncated - Check that the length is not too large for the iova - Check that lengths > 4G don't overflow the GENMASK
