Summary
netfilter: nf_tables: Fix potential data-race in __nft_flowtable_type_get()
Details

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

netfilter: nf_tables: Fix potential data-race in _nftflowtabletypeget()

nftunregisterflowtabletype() within nfflowinetmodule_exit() can concurrent with __nftflowtabletypeget() within nftablesnewflowtable(). And thhere is not any protection when iterate over nftables_flowtables list in _nftflowtabletypeget(). Therefore, there is pertential data-race of nftablesflowtables list entry.

Use listforeachentryrcu() to iterate over nftablesflowtables list in __nftflowtabletypeget(), and use rcureadlock() in the caller nftflowtabletypeget() to protect the entire type query process.
