Technical description

In the Linux kernel, the following vulnerability has been resolved:

RDMA/hns: Fix soft lockup during bt pages loop

Driver runs a for-loop when allocating bt pages and mapping them with

buffer pages. When a large buffer (e.g. MR over 100GB) is being allocated,

it may require a considerable loop count. This will lead to soft lockup:
