In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: Fix potential data-race in __nftobjtypeget() nftunregister_obj() can concurrent with __nftobjtypeget(), and there is not any protection when iterate over nftables_objects list in __nftobjtypeget(). Therefore, there is potential data-race of nftablesobjects list entry. Use listforeachentryrcu() to iterate over nftables_objects list in __nftobjtypeget(), and use rcureadlock() in the caller nftobjtypeget() to protect the entire type query process.
