Description
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: HWS, Handle destroying table that has a miss table
If a table has a miss table that was created by
'mlx5hws_table_set_default_miss' API function, its miss_tbl
keeps the table that points to it in a list.
If such table is deleted, we need to also remove it from the
miss_tbl list, otherwise the node in miss_tbl list will contain
garbage.
