Details

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

RDMA/mlx5: Initialize obj_event->obj_sub_list before xa_insert

The obj_event may be loaded immediately after inserted, then if the list_head is not initialized then we may get a poisonous pointer. This fixes the crash below:
