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

netfilter: nf_tables: make nft_object rhltable per table

The nft_object rhltable is global, this allows for accessing objects

that are being dismangled from lookup path by other existing netns.

Given the nft_obj_destroy() releases the object inmediately, this might

lead to use-after-free of these objects that are being released.

Make the existing rhltable per table to address this issue to deal with

with the nft_rcv_nl_event() path too.

Update nft_obj_lookup() to take the table as non-const, otherwise,

compiler complains when passing the objname_ht to rhltable_lookup(). (NVD)
