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

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

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

nftunregisterexpr() can concurrent with __nftexprtype_get(), and there is not any protection when iterate over nftablesexpressions list in _nftexprtypeget(). Therefore, there is potential data-race of nftablesexpressions list entry.

Use listforeachentryrcu() to iterate over nftablesexpressions list in __nftexprtypeget(), and use rcureadlock() in the caller nftexprtypeget() to protect the entire type query process.
